United States Statutes at Large
–
Each act and resolution of Congress is called a slip law, which is classified as either public law or private law, and designated and numbered accordingly. At the end of a Congress session, slip laws are compiled into Statutes at Large and they are part of a three-part model for publication of federal statutes consisting of slip laws, session laws, and codification. Today, large portions of slip laws denominated as public laws are now drafted as amendments to the United States Code. Once enacted into law, an Act will be published in the Statutes at Large and will add to, modify, provisions of a public law that contains only enacting clauses, effective dates, and similar matters are not generally codified. Private laws also are not generally codified, some portions of the United States Code have been enacted as positive law and other portions have not been so enacted. Publication of the United States Statutes at Large began in 1845 by the firm of Little, Brown. During Little, Brown and Companys time as publisher, Richard Peters, George Minot, in 1874, Congress transferred the authority to publish the Statutes at Large to the Government Printing Office under the direction of the Secretary of State. 633, was enacted July 30,1947 and directed the Secretary of State to compile, edit, index,980, was enacted September 23,1950 and directed the Administrator of General Services to compile, edit, index, and publish the Statutes at Large. Since 1985 the Statutes at Large have been prepared and published by the Office of the Federal Register of the National Archives, sometimes very large or long Acts of Congress are published as their own volume of the Statutes at Large. For example, the Internal Revenue Code of 1954 was published as volume 68A of the Statutes at Large. Volumes 1 to 18 of the Statutes at Large made available by the Library of Congress Volumes 1 to 64 of the Statutes at Large made available by the Congressional Data Coalition via LEGISWORKS

Militia Act of 1903
–
It also provided federal funds to the National Guard to pay for equipment and training, including annual summer encampments. During the nineteenth century, the militia in each U. S. state, under these laws, the question of state versus federal control of the militia was unresolved. As a result, the government could not rely on the militia for national defense. Because the issue of state versus federal control was not resolved and these units of United States Volunteers were not militia, though often they consisted of militia units which had volunteered en masse, nor were they part of the regular Army. This solution was employed during the Mexican–American War, and in the Union Army during the American Civil War, during the Spanish–American War some volunteer units were organized, most notably the 1st United States Volunteer Cavalry Regiment, nicknamed Rough Riders. The federal government also mobilized several National Guard units which volunteered en masse and were accepted as volunteer units. As a result of the problems identified during the Spanish–American War, Secretary of War Elihu Root and other leaders took steps to reform the Army. Roots allies included Charles Dick, Congressman from Ohio and Chairman of the House Militia Affairs Committee, Dick was a veteran of the Spanish–American War and a longtime National Guard member who attained the rank of Major General as commander of the Ohio National Guard. Dick championed the Militia Act of 1903, which known as the Dick Act. The Dick Act included $2 million for National Guard units to modernize equipment, the National Guard in each state was also required to carry out a uniform schedule of weekend or weeknight drills and annual summer training camps. In addition, the War Department agreed to fund the attendance of Guard officers at Army schools, the War Department also agreed to organize joint Army-National Guard exercises and training encampments. In return, the government gained greater control over the National Guard. The President of the United States was empowered to call up the National Guard for up to nine months to repel invasion, suppress rebellion, Guardsmen had to answer a presidential call or face court-martial. States had to organize, equip, and train their units in accordance with the policies and procedures of the regular Army, if Guard units failed to meet Army standards, they would lose federal recognition and federal funding. The Dick Act was amended several times, in 1908, The nine-month limit on federal service was dropped, and the President was empowered to set the length of federal service. In addition, the 1908 law stated that during a mobilization the National Guard had to be federalized before the Army could organize volunteer units. The 1908 law also included the creation of the Division of Militia Affairs as the Army agency responsible for overseeing federal training and administrative requirements for the National Guard. The National Defense Act of 1916 doubled the number of required drill periods from 24 to 48, in addition, the War Department was enabled to centrally plan for the National Guards authorized strength, and the number and types of National Guard units in each state

United States Army
–
The United States Armed Forces are the federal armed forces of the United States. They consist of the Army, Marine Corps, Navy, Air Force, from the time of its inception, the military played a decisive role in the history of the United States. A sense of unity and identity was forged as a result of victory in the First Barbary War. Even so, the Founders were suspicious of a permanent military force and it played an important role in the American Civil War, where leading generals on both sides were picked from members of the United States military. Not until the outbreak of World War II did a standing army become officially established. The National Security Act of 1947, adopted following World War II and during the Cold Wars onset, the U. S. military is one of the largest militaries in terms of number of personnel. It draws its personnel from a pool of paid volunteers. As of 2016, the United States spends about $580.3 billion annually to fund its military forces, put together, the United States constitutes roughly 40 percent of the worlds military expenditures. For the period 2010–14, the Stockholm International Peace Research Institute found that the United States was the worlds largest exporter of major arms, the United States was also the worlds eighth largest importer of major weapons for the same period. The history of the U. S. military dates to 1775 and these forces demobilized in 1784 after the Treaty of Paris ended the War for Independence. All three services trace their origins to the founding of the Continental Army, the Continental Navy, the United States President is the U. S. militarys commander-in-chief. Rising tensions at various times with Britain and France and the ensuing Quasi-War and War of 1812 quickened the development of the U. S. Navy, the reserve branches formed a military strategic reserve during the Cold War, to be called into service in case of war. Time magazines Mark Thompson has suggested that with the War on Terror, Command over the armed forces is established in the United States Constitution. The sole power of command is vested in the President by Article II as Commander-in-Chief, the Constitution also allows for the creation of executive Departments headed principal officers whose opinion the President can require. This allowance in the Constitution formed the basis for creation of the Department of Defense in 1947 by the National Security Act, the Defense Department is headed by the Secretary of Defense, who is a civilian and member of the Cabinet. The Defense Secretary is second in the chain of command, just below the President. Together, the President and the Secretary of Defense comprise the National Command Authority, to coordinate military strategy with political affairs, the President has a National Security Council headed by the National Security Advisor. The collective body has only power to the President

National Guard of the United States
–
All members of the National Guard of the United States are also members of the militia of the United States as defined by 10 U. S. C. National Guard units are under the control of the state. The majority of National Guard soldiers and airmen hold a civilian job full-time while serving part-time as a National Guard member, local militias were formed from the earliest English colonization of the Americas in 1607. The first colony-wide militia was formed by Massachusetts in 1636 by merging small older local units, the various colonial militias became state militias when the United States became independent. The title National Guard was used from 1824 by some New York State militia units, National Guard became a standard nationwide militia title in 1903, and specifically indicated reserve forces under mixed state and federal control from 1933. The first muster of militia forces in what is today the United States took place on September 16,1565, appropriately enough, this muster occurred in the shadow of an oncoming hurricane. This Spanish militia tradition and the English tradition that would be established to the north would provide the nucleus for Colonial defense in the New World. The militia tradition continued with the first permanent English settlements in the New World, Jamestown Colony and Plymouth Colony both had militia forces, which initially consisted of every able bodied adult male. By the mid-1600s every town had at least one militia company, as a result of the Spanish–American War, Congress was called upon to reform and regulate the training and qualification of state militias. The first national laws regulating the militia were the Militia acts of 1792, in 1903, with passage of the Dick Act, the predecessor to the modern-day National Guard was formed. It required the states to divide their militias into two sections, the law recommended the title National Guard for the first section, known as the organized militia, and Reserve Militia for all others. During World War I, Congress passed the National Defense Act of 1916, Congress also authorized the states to maintain Home Guards, which were reserve forces outside the National Guards being deployed by the Federal Government. The National Guard of the states, territories, and the District of Columbia serves as part of the first-line of defense for the United States. C. Where the National Guard operates under the President of the United States or his designee, the governors exercise control through the state adjutants general. The National Guard may be called up for duty by the governors to help respond to domestic emergencies and disasters, such as hurricanes, floods. The National Guard is administered by the National Guard Bureau, which is a joint activity of the Army, the National Guard Bureau provides a communication channel for state National Guards to the DoD. S. C. The National Guard Bureau is headed by the Chief of the National Guard Bureau, prior to 2008, the functions of Agricultural Development Teams were within Provincial Reconstruction Teams of the US Government. Today, ADTs consist of soldiers and airmen from the Army National Guard, today, ADTs bring an effective platform for enhanced dialogue, building confidence, sharing interests, and increasing cooperation amongst the disparate peoples and tribes of Afghanistan

Reserve Officers' Training Corps
–
The Reserve Officers Training Corps are a group of college-based officer training programs for training commissioned officers of the United States Armed Forces. ROTC officers serve in all branches of the U. S. armed forces, under ROTC, a student may receive a competitive, merit-based scholarship, covering all or part of college tuition, in return for an obligation of active military service after graduation. The U. S. Coast Guard offers a program to ROTC under a different name. The students participate in regular drills during the year. Some of the training that is offered to cadets in the Army ROTC program are, Airborne, Air Assault, Mountain Warfare, WHINSEC. Army ROTC units are organized as brigades, battalions, and companies, Air Force ROTC units are detachments with the students organized into wings, groups, squadrons, and flights. Army and Air Force ROTC students are referred to as cadets, Navy ROTC units are organized as battalions, and also include NROTC students under Marine Option who will eventually be commissioned as officers in the Marine Corps. Marine NROTC students may be formed in a company when the program includes sufficient numbers. All Navy ROTC students are referred to as midshipmen, the term of obligatory service varies based on the type of commission the cadet or midshipman receives, as well as any scholarship contract signed. They can serve as duty or in a reserve status. Additionally, a cadet on active duty can receive either a regular appointment or a reserve appointment and this affects the required years, as well as how many must be completed on active duty, in an active reserve capacity, or in the Individual Ready Reserve. Under federal law, graduates of an ROTC scholarship program incur an active duty service obligation. Recipients incur an eight-year MSO if they accept a commission and serve in a reserve component, finally, recipients incur at least a six-year MSO and up to an eight-year ADSO if they accept a commission and serve in a reserve component with at least two years of active duty. Army ROTC students who receive an Army ROTC scholarship or enter the Army ROTC Advanced Course must agree to complete a period of service. This can include three active duty, with the balance in the IRR. The service obligation for a Navy ROTC student is five years in the Navy, the active-duty service obligation for an Air Force ROTC student is four years, or eight years for Combat Systems Officers, or six years Air Battle Management officers, or ten years for pilots. The concept of ROTC in the United States began with the Morrill Act of 1862 which established the land-grant colleges, part of the federal governments requirement for these schools was that they include military tactics as part of their curriculum, forming what became known as ROTC. The college from which ROTC originated is Norwich University in Northfield, Norwich was founded in 1819 at Norwich, Vermont, as the American Literary, Scientific and Military Academy

President of the United States
–
The President of the United States is the head of state and head of government of the United States. The president directs the executive branch of the government and is the commander-in-chief of the United States Armed Forces. The president is considered to be one of the worlds most powerful political figures, the role includes being the commander-in-chief of the worlds most expensive military with the second largest nuclear arsenal and leading the nation with the largest economy by nominal GDP. The office of President holds significant hard and soft power both in the United States and abroad, Constitution vests the executive power of the United States in the president. The president is empowered to grant federal pardons and reprieves. The president is responsible for dictating the legislative agenda of the party to which the president is a member. The president also directs the foreign and domestic policy of the United States, since the office of President was established in 1789, its power has grown substantially, as has the power of the federal government as a whole. However, nine vice presidents have assumed the presidency without having elected to the office. The Twenty-second Amendment prohibits anyone from being elected president for a third term, in all,44 individuals have served 45 presidencies spanning 57 full four-year terms. On January 20,2017, Donald Trump was sworn in as the 45th, in 1776, the Thirteen Colonies, acting through the Second Continental Congress, declared political independence from Great Britain during the American Revolution. The new states, though independent of each other as nation states, desiring to avoid anything that remotely resembled a monarchy, Congress negotiated the Articles of Confederation to establish a weak alliance between the states. Out from under any monarchy, the states assigned some formerly royal prerogatives to Congress, only after all the states agreed to a resolution settling competing western land claims did the Articles take effect on March 1,1781, when Maryland became the final state to ratify them. In 1783, the Treaty of Paris secured independence for each of the former colonies, with peace at hand, the states each turned toward their own internal affairs. Prospects for the convention appeared bleak until James Madison and Edmund Randolph succeeded in securing George Washingtons attendance to Philadelphia as a delegate for Virginia. It was through the negotiations at Philadelphia that the presidency framed in the U. S. The first power the Constitution confers upon the president is the veto, the Presentment Clause requires any bill passed by Congress to be presented to the president before it can become law. Once the legislation has been presented, the president has three options, Sign the legislation, the bill becomes law. Veto the legislation and return it to Congress, expressing any objections, in this instance, the president neither signs nor vetoes the legislation

United States Army Aviation Branch
–
The United States Army Aviation Branch is the administrative organization within the United States Army responsible for doctrine, manning and configuration for all aviation units. The Army would develop a new concept of using the helicopter that would show promise during the Korean War. Army Aviation traces its origins back to the American Civil War, both Union and Confederate forces used hydrogen-filled balloons to direct artillery fire, marking the beginning of U. S. military aeronautics and of aerial support of Army ground forces. The Army also used balloons during the Spanish–American War and World War I, Army Aviation began in 1909 with the Army’s acquisition of its first heavier-than-air aircraft, an airplane built to Army specifications by the Wright brothers. During World War I, the Armys aircraft strength grew from a few dozen to more than 11,000 planes, the Army Air Service was created in May 1918. After World War I, General William Mitchell and other Air Service leaders spoke out forcefully in favor of an independent air force, since they envisioned aviation as a separate striking force, capable of independent operations, they opposed its remaining an arm of the ground forces. Although Congress as well as most Army leaders rejected Mitchells argument, the Air Service did become a combat arm, equal in status to the infantry, cavalry. During the 1930s, many Army Air Corps leaders became preoccupied with strategic air operations, like Billy Mitchell before them, they advocated using air power independently of the Army ground forces to destroy enemy targets behind the lines of combat. This Air Corps emphasis on strategic operations disturbed some ground forces leaders, aerial support was particularly vital for artillery fire adjustment. The Army experimented with using small aircraft for artillery fire adjustment and other functions in maneuvers at Camp Beauregard. The tests were repeated on a scale in the Army maneuvers in Louisiana, Tennessee, Texas. The Armys Grasshoppers, as these light planes came to be called, proved to be more effective than the larger Air Corps planes used for the same purposes. It was this new World War II-era phenomenon with its few small single-engine spotter planes, organic Army Aviation, Organic Army Aviation first entered into combat in November 1942 on the coast of North Africa. After the creation of the Army Air Forces, the Army Ground Forces retained the use of aircraft for artillery forward observation. First use of the helicopter in combat is credited to the USAAF 1st Air Commando Group in Burma in 1943, the 1ACG operated six Sikorsky R-4 helicopters primarily for air rescue and medical evacuation. When the United States Air Force was established as a service in 1947. The Korean War and Vietnam War proved the capabilities of these aviation assets to perform a variety of missions not covered by the Air Force. The Korean War provided new challenges and opportunities for Army Aviation, Organic Army Aviation had acquired its first helicopters, thirteen H-13 Sioux, in 1947, shortly before the U. S. Air Force became independent of the Army

Gunpowder
–
Gunpowder, also known as black powder, is the earliest known chemical explosive. It is a mixture of sulfur, charcoal, and potassium nitrate, the sulfur and charcoal act as fuels, and the saltpeter is an oxidizer. Black powder firearms are in limited use today in hunting, shooting, Black powder has been replaced for most industrial uses by high explosives such as dynamite. Black powder is assigned the UN number UN0027 and has a class of 1. 1D. It has a point of approximately 427–464 °C. The specific flash point may vary based on the composition of the gunpowder. Gunpowders specific gravity is 1. 70–1.82 or 1. 92–2.08, Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate at subsonic speeds, whereas high explosives detonate, ignition of the powder packed behind a bullet must generate enough pressure to force it from the muzzle at high speed, but not enough to rupture the gun barrel. Gunpowder thus makes a good propellant, but is suitable for shattering rock or fortifications. Gunpowder was widely used to fill artillery shells and in mining and civil engineering to blast rock until the half of the 19th century. Black powder is used as a delay element in various munitions where its slow-burning properties are valuable. The spread of gunpowder across Asia from China is widely attributed to the Mongols, the earliest record of a written formula for gunpowder appears in the 11th century Song dynasty text, Wujing Zongyao. This discovery led to the invention of fireworks and the earliest gunpowder weapons in China, in the centuries following the Chinese discovery, gunpowder weapons began appearing in the Muslim world and Europe. The technology spread from China through the Middle East or Central Asia, the earliest Western accounts of gunpowder appear in texts written by English philosopher Roger Bacon in the 13th century. The most ardent protagonists were Nathaniel Halhad, Johann Backmann, Quintin Craufurd, however, due to lack of sufficient proof, these theories have not been widely accepted. A major problem confronting the study of the history of gunpowder is ready access to sources close to the events described. The translation difficulty has led to errors or loose interpretations bordering on artistic licence, early writings potentially mentioning gunpowder are sometimes marked by a linguistic process where old words acquired new meanings. For instance, the Arabic word naft transitioned from denoting naphtha to denoting gunpowder, saltpeter was known to the Chinese by the mid-1st century AD and there is strong evidence of the use of saltpeter and sulfur in various largely medicinal combinations

Preparedness Movement
–
Wood advocated a summer training school for reserve officers to be held in Plattsburg, New York. The movement was opposed by President Woodrow Wilson, who believed the United States should be in a position of armed neutrality. Several organizations were formed around the Preparedness Movement and held parades, after the Lusitania was sunk by German U-boats on May 7,1915 and Pancho Villa launched his raid against Columbus, New Mexico, Wilsons attitude changed. Congress passed the National Defense Act of 1916 in June 1916 to authorize an increase in the size of the military. In 1915, a strong movement emerged. It argued that the United States needed to build up strong naval and land forces for defensive purposes. A representative leader was Paul D. Cravath, one of New Yorks foremost corporation lawyers, for Cravath, in his mid-fifties when the war began, the conflict served as an epiphany, sparking an interest in international affairs that dominated his remaining career. Fiercely Anglophile, he strongly supported US intervention in the war, reform to them meant UMT or universal military training, i. e. conscription. They proposed a service program under which the 600,000 men who turned 18 every year would be required to spend six months in military training. The small regular army would serve as a training agency. Antimilitarists and pacifists — strong in Protestant churches and womens groups — protested the plan would make the US resemble Germany, advocates retorted that military service was an essential duty of citizenship, and that without the commonality provided by such service the nation would splinter into antagonistic ethnic groups. One spokesman promised that UMT would become a melting pot. Furthermore, they promised, the discipline and training would make for a paid work force. Suggestions by labor unions that talented working class youth be invited to Plattsburg were ignored, the preparedness movement was distant not only from the working classes but also from the middle class leadership of most of small town America. The National Guard on the hand was securely rooted in state and local politics. The guard was one of the few institutions that accepted African-Americans on an equal footing with whites. The Democratic Party saw the movement as a threat. Roosevelt, Root and Wood were prospective Republican presidential candidates, more subtly, the Democrats were rooted in localism that appreciated the National Guard, and the voters were hostile to the rich and powerful in the first place

Pancho Villa
–
Francisco Pancho Villa was a Mexican Revolutionary general and one of the most prominent figures of the Mexican Revolution. As commander of the División del Norte in the Constitutionalist Army, given the areas size and mineral wealth, it provided him with extensive resources. Villa was also provisional Governor of Chihuahua in 1913 and 1914, Villa can be credited with decisive military victories leading to the ousting of Victoriano Huerta from the presidency in July 1914. Villa then fought his erstwhile leader in the coalition against Huerta, Villa was in alliance with southern revolutionary Emiliano Zapata, who remained fighting in his own region of Morelos. The two revolutionary generals briefly came together to take Mexico City after Carranzas forces retreated from it, later, Villas heretofore undefeated División del Norte engaged the military forces of Carranza under Carrancista general Álvaro Obregón and was defeated in the 1915 Battle of Celaya. Villa was again defeated by Carranza,1 November 1915, at the Second Battle of Agua Prieta 1 November 1915, after which Villas army collapsed as a significant military force. Villa subsequently led a hit and run raid against the small U. S. -Mexican border town in the Battle of Columbus 9 March 1916, the U. S. government sent U. S. Army General John J. In 1923, as elections approached, he re-involved himself in Mexican politics. Shortly thereafter he was assassinated, most likely on the orders of Obregón, after his death, he was excluded from the pantheon of revolutionary heroes until the Sonoran generals Obregón and Calles, whom he battled during the Revolution, were gone from the political stage. Villas exclusion from the narrative of the Revolution might have contributed to his continued posthumous popular acclaim. He was celebrated during the Revolution and long afterward by corridos, movies about his life, in 1976, his remains were reburied in the Monument to the Revolution in Mexico City in a huge public ceremony not attended by his widow Luz Corral. Villa told a number of conflicting stories about his early life, according to most sources, he was born on 5 June 1878, and named José Doroteo Arango Arámbula at birth. His father was a sharecropper named Agustín Arango, and his mother was Micaela Arámbula and he grew up at the Rancho de la Coyotada, one of the largest haciendas in the state of Durango. The familys residence now houses the Casa de Pancho Villa historic museum in San Juan del Rio, Doroteo later claimed to be the son of the bandit Agustín Villa, but according to at least one scholar, the identity of his real father is still unknown. He wasthe oldest of five children, as a child, he received some education from a local church-run school, but was not proficient in more than basic literacy. He quit school to help his mother after his father died and he became a bandit at some point early on, but also worked as a sharecropper, muleskinner, butcher, bricklayer, and foreman for a U. S. railway company. However, the veracity of this story is questionable, eventually, he became a member of a bandit band headed by Ignacio Parra, one of the most famous bandits in Durango at the time. As a bandit, he went by the name Arango, in 1902, the rurales, the crack rural police force of President Porfirio Díaz, arrested Pancho for stealing mules and for assault

Columbus, New Mexico
–
Columbus is a village in Luna County, New Mexico, United States, about three miles north of the Mexican border. The population was 1,765 at the 2000 census, Columbus was established in 1891 just across the Mexican border from Palomas, Chihuahua, Mexico, and named after 15th century explorer Christopher Columbus. In 1902, the village was moved three miles north when the El Paso and Southwestern Railroad built its Columbus Station and this Station is now converted into a museum run by the Columbus Historical Society. Around 1905, it was a small town with a community of a hundred residents. By this time, Columbus had only one store, a saloon. In time, a school was built, and Perrow G. Mosely established the Columbus News. By 1915, the town had seven hundred residents, the Columbus State Bank was built, four hotels were constructed, several stores, at that time, Columbus also possessed rich silver, copper, lead, and zinc deposits. Villas army burned a part of the town and killed seven or eight soldiers and 10 residents before retreating back into Mexico, United States President Woodrow Wilson responded to the Columbus raid by sending 10,000 troops under Brigadier General John J. Pershing to Mexico to pursue Villa. This was known as the Punitive Mexican Expedition or Pancho Villa Expedition, the expedition was eventually called off after failing to find Villa, who had successfully escaped. Camp Furlong activity was greatly reduced, the army decided to close their camp, and the El Paso and Southwestern Railroad stopped service in Columbus. After all these events the economy naturally faded over time, in the 1990s Columbus started to rise again, with the development of city and state parks, museums, RV parks, and all the history involving the city. A few artists showed up, and Columbus became a place to visit or perhaps to live. In July 2011, Columbus dissolved its police force after a scandal that involved its village officials. The mayor, a trustee, a former police chief. The case was prosecuted by the United States Attorney from El Paso, Texas before United States District Court Judge Robert Brack in Las Cruces, of the 11 people charged, ten pleaded guilty, with one person still at large. Sentences ranged from five years in prison to two years probation. Columbus is located at 31°49′51″N 107°38′30″W, according to the United States Census Bureau, the village has a total area of 2.8 square miles, all land. The village is three miles north of the international border between the United States of America and Mexico

World War I
–
World War I, also known as the First World War, the Great War, or the War to End All Wars, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history and it was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. The war drew in all the worlds great powers, assembled in two opposing alliances, the Allies versus the Central Powers of Germany and Austria-Hungary. These alliances were reorganised and expanded as more nations entered the war, Italy, Japan, the trigger for the war was the assassination of Archduke Franz Ferdinand of Austria, heir to the throne of Austria-Hungary, by Yugoslav nationalist Gavrilo Princip in Sarajevo on 28 June 1914. This set off a crisis when Austria-Hungary delivered an ultimatum to the Kingdom of Serbia. Within weeks, the powers were at war and the conflict soon spread around the world. On 25 July Russia began mobilisation and on 28 July, the Austro-Hungarians declared war on Serbia, Germany presented an ultimatum to Russia to demobilise, and when this was refused, declared war on Russia on 1 August. Germany then invaded neutral Belgium and Luxembourg before moving towards France, after the German march on Paris was halted, what became known as the Western Front settled into a battle of attrition, with a trench line that changed little until 1917. On the Eastern Front, the Russian army was successful against the Austro-Hungarians, in November 1914, the Ottoman Empire joined the Central Powers, opening fronts in the Caucasus, Mesopotamia and the Sinai. In 1915, Italy joined the Allies and Bulgaria joined the Central Powers, Romania joined the Allies in 1916, after a stunning German offensive along the Western Front in the spring of 1918, the Allies rallied and drove back the Germans in a series of successful offensives. By the end of the war or soon after, the German Empire, Russian Empire, Austro-Hungarian Empire, national borders were redrawn, with several independent nations restored or created, and Germanys colonies were parceled out among the victors. During the Paris Peace Conference of 1919, the Big Four imposed their terms in a series of treaties, the League of Nations was formed with the aim of preventing any repetition of such a conflict. This effort failed, and economic depression, renewed nationalism, weakened successor states, and feelings of humiliation eventually contributed to World War II. From the time of its start until the approach of World War II, at the time, it was also sometimes called the war to end war or the war to end all wars due to its then-unparalleled scale and devastation. In Canada, Macleans magazine in October 1914 wrote, Some wars name themselves, during the interwar period, the war was most often called the World War and the Great War in English-speaking countries. Will become the first world war in the sense of the word. These began in 1815, with the Holy Alliance between Prussia, Russia, and Austria, when Germany was united in 1871, Prussia became part of the new German nation. Soon after, in October 1873, German Chancellor Otto von Bismarck negotiated the League of the Three Emperors between the monarchs of Austria-Hungary, Russia and Germany

Virginia
–
Virginia is a state located in the Mid-Atlantic region of the United States, as well as in the historic Southeast. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, the capital of the Commonwealth is Richmond, Virginia Beach is the most populous city, and Fairfax County is the most populous political subdivision. The Commonwealths estimated population as of 2014 is over 8.3 million, the areas history begins with several indigenous groups, including the Powhatan. In 1607 the London Company established the Colony of Virginia as the first permanent New World English colony, slave labor and the land acquired from displaced Native American tribes each played a significant role in the colonys early politics and plantation economy. Although the Commonwealth was under one-party rule for nearly a century following Reconstruction, the Virginia General Assembly is the oldest continuous law-making body in the New World. The state government was ranked most effective by the Pew Center on the States in both 2005 and 2008 and it is unique in how it treats cities and counties equally, manages local roads, and prohibits its governors from serving consecutive terms. Virginias economy changed from agricultural to industrial during the 1960s and 1970s. Virginia has an area of 42,774.2 square miles, including 3,180.13 square miles of water. Virginias boundary with Maryland and Washington, D. C. extends to the mark of the south shore of the Potomac River. The southern border is defined as the 36° 30′ parallel north, the border with Tennessee was not settled until 1893, when their dispute was brought to the U. S. Supreme Court. The Chesapeake Bay separates the portion of the Commonwealth from the two-county peninsula of Virginias Eastern Shore. The bay was formed from the river valleys of the Susquehanna River. Many of Virginias rivers flow into the Chesapeake Bay, including the Potomac, Rappahannock, York, and James, the Tidewater is a coastal plain between the Atlantic coast and the fall line. It includes the Eastern Shore and major estuaries of Chesapeake Bay, the Piedmont is a series of sedimentary and igneous rock-based foothills east of the mountains which were formed in the Mesozoic era. The region, known for its clay soil, includes the Southwest Mountains around Charlottesville. The Blue Ridge Mountains are a province of the Appalachian Mountains with the highest points in the state. The Ridge and Valley region is west of the mountains and includes the Great Appalachian Valley, the region is carbonate rock based and includes Massanutten Mountain. The Cumberland Plateau and the Cumberland Mountains are in the southwest corner of Virginia, in this region, rivers flow northwest, with a dendritic drainage system, into the Ohio River basin

Julius Kahn (congressman)
–
Julius Kahn was a United States Congressman who was succeeded by his wife Florence Prag Kahn after his death. Kahn was born in Kuppenheim, in the Grand Duchy of Baden and he immigrated to the United States with his parents, who settled in California in 1866. After studying law in San Francisco, he was elected a member of the State Assembly in 1892 and he has been described by the American Jerusalem as among the most influential Jews in San Francisco—as well as national–civic life, from the middle of the 19th century into the 1930s. He was elected as a Republican to the 56th and 57th Congresses, during his time in the House of Representatives he was noted as an advocate of military preparedness. He helped draft and secure the passage of the National Defense Act of 1916, the Selective Service Act of 1917, and he served as chairman of Committee on Military Affairs. At the time of his death, he had been re-elected to the 69th Congress and his wife, Florence Prag Kahn, succeeded him in Congress and served until 1937. He was buried in the Home of Peace Cemetery in Colma, a well-known playground in San Francisco was named in his honor. Biographical Directory of the United States Congress

California
–
California is the most populous state in the United States and the third most extensive by area. Located on the western coast of the U. S, California is bordered by the other U. S. states of Oregon, Nevada, and Arizona and shares an international border with the Mexican state of Baja California. Los Angeles is Californias most populous city, and the second largest after New York City. The Los Angeles Area and the San Francisco Bay Area are the nations second- and fifth-most populous urban regions, California also has the nations most populous county, Los Angeles County, and its largest county by area, San Bernardino County. The Central Valley, an agricultural area, dominates the states center. What is now California was first settled by various Native American tribes before being explored by a number of European expeditions during the 16th and 17th centuries, the Spanish Empire then claimed it as part of Alta California in their New Spain colony. The area became a part of Mexico in 1821 following its war for independence. The western portion of Alta California then was organized as the State of California, the California Gold Rush starting in 1848 led to dramatic social and demographic changes, with large-scale emigration from the east and abroad with an accompanying economic boom. If it were a country, California would be the 6th largest economy in the world, fifty-eight percent of the states economy is centered on finance, government, real estate services, technology, and professional, scientific and technical business services. Although it accounts for only 1.5 percent of the states economy, the story of Calafia is recorded in a 1510 work The Adventures of Esplandián, written as a sequel to Amadis de Gaula by Spanish adventure writer Garci Rodríguez de Montalvo. The kingdom of Queen Calafia, according to Montalvo, was said to be a land inhabited by griffins and other strange beasts. This conventional wisdom that California was an island, with maps drawn to reflect this belief, shortened forms of the states name include CA, Cal. Calif. and US-CA. Settled by successive waves of arrivals during the last 10,000 years, various estimates of the native population range from 100,000 to 300,000. The Indigenous peoples of California included more than 70 distinct groups of Native Americans, ranging from large, settled populations living on the coast to groups in the interior. California groups also were diverse in their organization with bands, tribes, villages. Trade, intermarriage and military alliances fostered many social and economic relationships among the diverse groups, the first European effort to explore the coast as far north as the Russian River was a Spanish sailing expedition, led by Portuguese captain Juan Rodríguez Cabrillo, in 1542. Some 37 years later English explorer Francis Drake also explored and claimed a portion of the California coast in 1579. Spanish traders made unintended visits with the Manila galleons on their trips from the Philippines beginning in 1565

Ohio

Ohio /oʊˈhaɪ. oʊ/ is a Midwestern state in the Great Lakes region of the United States. Ohio is the 34th largest by area, the 7th most populous, the states capital and largest city is Columbus. The state takes its name from the Ohio River, the name originated from the Iroquois word ohi-yo’, meaning great river or large creek. Partitioned from the Northwest Territory, the state was admitted to the Union as the 17th state on March 1,1803, Ohio is historically known as the Buckeye State after its Ohio buckeye trees, and Ohioans are also known as Buckeyes. Ohio occupies 16 seats in the United States House of Representatives, Ohio is known for its status as both a swing state and a bellwether in national elections. Six Presidents of the United States have been elected who had Ohio as their home state, Ohios geographic location has proven to be an asset for economic growth and expansion. Because Ohio links the Northeast to the Midwest, much cargo, Ohio has the nations 10th largest highway network, and is within a one-day drive of 50% of North Americas population and 70% of North Americas manufacturing capacity. To the north, Lake Erie gives Ohio 312 miles of coastline, Ohios southern border is defined by the Ohio River, and much of the northern border is defined by Lake Erie. Ohios neighbors are Pennsylvania to the east, Michigan to the northwest, Ontario Canada, to the north, Indiana to the west, Kentucky on the south, Ohio is bounded by the Ohio River, but nearly all of the river itself belongs to Kentucky and West Virginia. Ohio has only that portion of the river between the rivers 1792 low-water mark and the present high-water mark, the border with Michigan has also changed, as a result of the Toledo War, to angle slightly northeast to the north shore of the mouth of the Maumee River. Much of Ohio features glaciated plains, with a flat area in the northwest being known as the Great Black Swamp. Most of Ohio is of low relief, but the unglaciated Allegheny Plateau features rugged hills, in 1965 the United States Congress passed the Appalachian Regional Development Act, at attempt to address the persistent poverty and growing economic despair of the Appalachian Region. This act defines 29 Ohio counties as part of Appalachia, the worst weather disaster in Ohio history occurred along the Great Miami River in 1913. Known as the Great Dayton Flood, the entire Miami River watershed flooded, as a result, the Miami Conservancy District was created as the first major flood plain engineering project in Ohio and the United States. Grand Lake St. Marys in the west central part of the state was constructed as a supply of water for canals in the era of 1820–1850. For many years this body of water, over 20 square miles, was the largest artificial lake in the world and it should be noted that Ohios canal-building projects were not the economic fiasco that similar efforts were in other states. Some cities, such as Dayton, owe their emergence to location on canals. Summers are typically hot and humid throughout the state, while winters generally range from cool to cold, precipitation in Ohio is moderate year-round

The Ohio State University, commonly referred to as Ohio State or OSU, is a large, primarily residential, public university in Columbus, Ohio. Founded in 1870 as a land-grant university and ninth university in Ohio with the Morrill Act of 1862, Hayes, and in 1878 the Ohio General Assembly passed a law changing the name to The Ohio State University. It has since grown into the third-largest university campus in the United States, along with its main campus in Columbus, Ohio State also operates a regional campus system with regional campuses in Lima, Mansfield, Marion, Newark, and Wooster. Ohio State athletic teams compete in Division I of the NCAA and are known as the Ohio State Buckeyes, athletes from Ohio State have won 100 Olympic medals. The university is a member of the Big Ten Conference for the majority of sports, the Ohio State mens ice hockey program competes in the Big Ten Conference, while its womens hockey program competes in the Western Collegiate Hockey Association. In addition, the OSU mens volleyball team is a member of the Midwestern Intercollegiate Volleyball Association, OSU is one of only 14 universities that plays Division I FBS football and Division I ice hockey. As of August 2015, the university had awarded a total of 714,512 degrees, alumni and former students have gone on to prominent careers in government, business, science, medicine, education, sports, and entertainment. Championed by the Republican stalwart Governor Rutherford B, Hayes, the Ohio State University was founded in 1870 as a land-grant university under the Morrill Act of 1862 as the Ohio Agricultural and Mechanical College. The school was originally within a community on the northern edge of Columbus. The university opened its doors to 24 students on September 17,1873, in 1878, the first class of six men graduated. The first woman graduated the following year, also in 1878, in light of its expanded focus, the Ohio legislature changed the name to the now-familiar The Ohio State University, with The as part of its official name. Ohio State began accepting students in the 1880s, and in 1891. It would later acquire colleges of medicine, dentistry, optometry, veterinary medicine, commerce, in 1916, Ohio State was elected into membership in the Association of American Universities. Michael V. Drake, former chancellor of the University of California, Irvine, in an attack against the campus on November 28,2016, an unrelated fluorine leak was called in for Watts Hall, resulting in the evacuation of the building to an outside courtyard. As firetrucks began to depart, Abdul Razak Ali Artan drove into the crowd, then emerged, the attack was stopped in under two minutes by OSU Police Officer Alan Horujko, who witnessed the attack after responding to the reported gas leak, and who shot and killed Artan. The universitys Buckeye Alert system was triggered and the campus was placed on lockdown, Ten were transported to local hospitals and one suspect was killed according to multiple sources. Local law enforcement and the FBI launched an investigation, according to authorities, Artan was inspired by terrorist propaganda from the Islamic State and radical Muslim cleric Anwar al-Awlaki. Ohio States 1, 764-acre main campus is about 2.5 miles north of the citys downtown, the historical center of campus is the Oval, quad of about 11 acres

Engineer
–
Engineers design materials, structures, and systems while considering the limitations imposed by practicality, regulation, safety, and cost. The word engineer is derived from the Latin words ingeniare and ingenium, the work of engineers forms the link between scientific discoveries and their subsequent applications to human and business needs and quality of life. His/her work is predominantly intellectual and varied and not of a mental or physical character. It requires the exercise of original thought and judgement and the ability to supervise the technical, he/she is thus placed in a position to make contributions to the development of engineering science or its applications. In due time he/she will be able to give authoritative technical advice, much of an engineers time is spent on researching, locating, applying, and transferring information. Indeed, research suggests engineers spend 56% of their time engaged in various information behaviours, Engineers must weigh different design choices on their merits and choose the solution that best matches the requirements. Their crucial and unique task is to identify, understand, Engineers apply techniques of engineering analysis in testing, production, or maintenance. Analytical engineers may supervise production in factories and elsewhere, determine the causes of a process failure and they also estimate the time and cost required to complete projects. Supervisory engineers are responsible for major components or entire projects, Engineering analysis involves the application of scientific analytic principles and processes to reveal the properties and state of the system, device or mechanism under study. Most engineers specialize in one or more engineering disciplines, numerous specialties are recognized by professional societies, and each of the major branches of engineering has numerous subdivisions. Civil engineering, for example, includes structural and transportation engineering and materials engineering include ceramic, metallurgical, mechanical engineering cuts across just about every discipline since its core essence is applied physics. Engineers also may specialize in one industry, such as vehicles, or in one type of technology. Several recent studies have investigated how engineers spend their time, that is, research suggests that there are several key themes present in engineers’ work, technical work, social work, computer-based work, information behaviours. Amongst other more detailed findings, a recent work sampling study found that engineers spend 62. 92% of their time engaged in work,40. 37% in social work. The time engineers spend engaged in activities is also reflected in the competencies required in engineering roles. There are many branches of engineering, each of which specializes in specific technologies, typically engineers will have deep knowledge in one area and basic knowledge in related areas. When developing a product, engineers work in interdisciplinary teams. For example, when building robots an engineering team will typically have at least three types of engineers, a mechanical engineer would design the body and actuators

He received a Silver Star for gallantry in action at El Caney, Mann also served in the Philippines in 1899 and the early 1900s. He graduated from the Army War College in 1905, from 1907 to 1909 Mann commanded the 6th Infantry Regiment at Fort William Henry Harrison, Montana, also temporarily commanding the Department of Dakota on several occasions. From 1910 to 1911 he commanded the Recruit Depot, at Jefferson Barracks, in 1911 he was assigned to the Armys General Staff, and from 1912 to 1913 he was Chief of Staff for the Eastern Department in New York City. He served as Chief of Staff for the division based in Texas City, in 1917 he was named to head the Armys Militia Bureau, receiving promotion to Major General. General Mann left the Militia Bureau and was succeeded by Jesse McI, Mann became the first commander of the 42nd Infantry Division, nicknamed the Rainbow Division, which was composed of National Guard units from 26 states and the District of Columbia. Mann led the Rainbow Division to France, but did not pass his physical exam and he then returned to the U. S. and commanded the Department of the East until he reached mandatory retirement age in late 1918.

National Guard Bureau
–
It was created by the Militia Act of 1903. The National Defense Authorization Act for Fiscal Year 2008, elevated the National Guard to a joint function of the Department of Defense. This act also elevated the Chief of the National Guard Bureau from Lieutenant General to General with the appointment of General Craig R. McKinley, the National Guard Bureau holds a unique status as both a staff and operation agency. United States Secretary of War Elihu Root militated for reform of the guard, in annual reports of 1901 of 1903. The Militia Act of 1792 was obsolete, the resulting Militia Act of 1903 became law. It gave federal status to the militia and required the militia of the States to conform to Regular Army organization. It dramatically increased funding of the militia, between 1903 and 1916, the federal government spent $53 million on the Guard, more than the total of the previous hundred years. The 1903 act authorized the creation of a section responsible for National Guard affairs. The Division remained a part of the Office of the Secretary of War until July 25,1910 when the Chief was directed to report directly to the Army Chief of Staff. The Division continued to perform under the jurisdiction of the Chief of Staff until the passage of the National Defense Act of June 3,1916. Then the Division of Militia Affairs became the Militia Bureau of the War Department, the National Defense Act of 1916 is the most important piece of legislation in the history of the National Guard. It transformed the militia from individual state forces into a Reserve Component of the U. S. Army—and made the term National Guard mandatory. The act stated that all units would have to be recognized. It increased the number of training days to 15, increased the number of yearly drills to 48. The 1916 act transformed the Division of Militia Affairs into a separate Militia Bureau, increasing its autonomy, eight new civilian positions were authorized, something which the various Chiefs had been requesting for years, the number of military assigned to the Bureau had grown to 13. The National Defense Act also authorized the President to assign two National Guard officers to duty with the Militia Bureau, the inclusion of National Guard officers in the Militia Bureau was an important step towards creating a centralized planning organization for the National Guard headed by its own officers. The first National Guard officer assigned to the Bureau was Major Louis C. Wilson of Texas in 1916, thus the National Guard Bureau was charged with the responsibility of maintaining high standards in the National Guard. Prior to 1910 the Chief of the Militia Bureau was a Regular Army officer and this situation changed on June 4,1920, when Congress passed an amendment to the National Defense Act of 1916

Pancho Villa Expedition
–
The Pancho Villa Expedition—now known officially in the United States as the Mexican Expedition but originally referred to as the Punitive Expedition, U. S. The expedition was launched in retaliation for Villas attack on the town of Columbus, New Mexico, the declared objective of the expedition by the Wilson administration was the capture of Villa. The Constitutionalist forces used arms at the town of Parral to resist passage of a U. S. Army column, the U. S. mission was changed to prevent further attacks on it by Mexican troops and to plan for war in the eventuality it broke out. When war was averted diplomatically, the expedition remained in Mexico until February 1917 to encourage Carranzas government to pursue Villa, feeling betrayed, Villa began attacking U. S. nationals and their property in northern Mexico. On November 26,1915, Villa sent a force to attack the city of Nogales and in the course of the ensuing battle, engaged with American forces before withdrawing. On January 11,1916, sixteen American employees of the American Smelting and Refining Company were removed from a train near Santa Isabel, Chihuahua, brigadier General John J. Raids were so commonplace, however, that the rumor was not seen as credible. Ten civilians and eight soldiers were killed in the attack, the raiders burned the town, stole horses and mules, and seized machine guns, ammunition and merchandise, before fleeing back to Mexico. However, Villas soldiers had suffered losses, with at least sixty-seven dead. Many of the casualties were inflicted when the machine gun troop of the 13th Cavalry led by 2nd Lt. John P, about thirteen of Villas wounded later died of their wounds, and five wounded Villistas taken prisoner by the Americans were tried and hanged for murder. Local lore in Columbus holds that the attack may have been caused by a merchant in Columbus who supplied Villa with arms and ammunition. Villa is said to have several thousand dollars in cash for the weapons. The next day, acting on the recommendations of the commanders of his cavalry regiments and this can and will be done in entirely friendly aid to the constituted authorities in Mexico and with scrupulous respect for the sovereignty of that Republic. The 2nd Provisional Cavalry Brigade reached Colonia Dublán after dark on March 17, the entire squadron flew to the advanced camp at Colonia Dublán on March 19–20, losing two aircraft in the process. Pershing immediately sent the 7th Cavalry south just after midnight on March 18 to begin the pursuit, persistent winter weather through early April, particularly bitterly cold nights at high altitude, made both pursuit and logistics more difficult. An additional regiment of cavalry and two of infantry were added to the expedition in late April, bringing its size to 4,800 men. This was the first use of convoys in a U. S. military operation. His headquarters advanced as far as the 1st Aero Squadrons field at Satevó, southeast of Chihuahua City, before falling back at the end of April. Villa had a head start on the pursuit, all but ensuring that his forces would successfully break up into smaller bands
