United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

United States Marine Corps
–
The U. S. Marine Corps is one of the four armed service branches in the U. S. Department of Defense and one of the seven uniformed services of the United States. The current Chairman of the Joint Chiefs of Staff, the military officer in the U. S. Armed Forces, is a Marine Corps general, the Marine Corps has been a component of the U. S. Department of the Navy since 30 June 1834, working closely with naval forces for training, transportation, and logistics. The USMC operates posts on land and aboard sea-going amphibious warfare ships around the world, two battalions of Continental Marines were formed on 10 November 1775 in Philadelphia as a service branch of infantry troops capable of fighting for independence both at sea and on shore. The role of the Corps has since grown and evolved, expanding to aerial warfare and earning popular titles such as, Americas third air force, and, second land army. By the mid-20th century, the U. S. Marine Corps had become a major theorist of and its ability to rapidly respond on short notice to expeditionary crises gives it a strong role in the implementation and execution of American foreign policy. As of 2016, the USMC has around 182,000 active duty members and it is the smallest of the U. S. The USMC serves as an expeditionary force-in-readiness and this last clause, while seemingly redundant given the Presidents position as Commander-in-chief, is a codification of the expeditionary responsibilities of the Marine Corps. It derives from similar language in the Congressional acts For the Better Organization of the Marine Corps of 1834, in 1951, the House of Representatives Armed Services Committee called the clause one of the most important statutory – and traditional – functions of the Marine Corps. In addition to its duties, the Marine Corps conducts Visit, Board, Search, and Seizure operations, as well as missions in direct support of the White House. The Marine Band, dubbed the Presidents Own by Thomas Jefferson, Marines from Ceremonial Companies A & B, quartered in Marine Barracks, Washington, D. C. The Executive Flight Detachment also provides transport to Cabinet members. The relationship between the Department of State and the U. S. Marine Corps is nearly as old as the corps itself, for over 200 years, Marines have served at the request of various Secretaries of State. After World War II, an alert, disciplined force was needed to protect American embassies, consulates, in 1947, a proposal was made that the Department of War furnish Marine Corps personnel for Foreign Service guard duty under the provisions of the Foreign Service Act of 1946. A formal Memorandum of Agreement was signed between the Department of State and the Secretary of the Navy on December 15,1948, during the first year of the MSG program,36 detachments were deployed worldwide. Continental Marines manned raiding parties, both at sea and ashore, the Advanced Base Doctrine of the early 20th century codified their combat duties ashore, outlining the use of Marines in the seizure of bases and other duties on land to support naval campaigns. Throughout the late 19th and 20th centuries, Marine detachments served aboard Navy cruisers, battleships, Marine detachments served in their traditional duties as a ships landing force, manning the ships weapons and providing shipboard security. Marines would develop tactics and techniques of amphibious assault on defended coastlines in time for use in World War II, during World War II, Marines continued to serve on capital ships

4th Marine Division (United States)
–
The 4th Marine Division is a reserve division in the United States Marine Corps. It is the combat element of the Marine Forces Reserve and is headquartered in New Orleans. This division was formed by the organization and redesignation of several other units, in March the 24th Marine Regiment was organized, and then in May it was split in two to supply the men for the 25th Marines. This war-time shuffling provided the building blocks for a new division. The units were separated, however, with the 24th Marines. The rest of the units were at Camp Lejeune, North Carolina and this East Coast echelon moved to Pendleton by train and transit of the Panama Canal in July and August. When all the units were finally together, the 4th Marine Division was formally activated on August 14,1943 and it was awarded two Presidential Unit Citations and a Navy Unit Commendation, and then deactivated 28 November 1945. The division patch worn on Saipan had a gold 4 on a scarlet background, the emblem was designed by SSgt John Fabion, a member of the Divisions Public Affairs Office before the Marshalls Campaign. Major General Harry Schmidt Major General Clifton B, cates Brigadier General James L. Underhill Brigadier General Samuel C. Cumming Brigadier General Franklin A. Hart Colonel William W. Rogers Colonel Matthew C. Background, Early in 1962, Secretary of Defense Robert S. McNamara indicated to the Congress that he wanted the Marine Corps to have a fourth division/wing team, to be formed of Ready Reserves. In April of that year, the Commandant of the Marine Corps announced a reorganization of the Marine Corps Reserve to be effective 1 July 1962. In this reorganization,53 reserve units were redesignated as 4th Marine Division units, Major General Robert E. Cushman, Jr. commanding general of Camp Pendleton was given the additional responsibility as the commanding general of the division. On 23 June 1966, the World War II division colors were presented to General Cushman, significantly at a 4th Marine Division Association meeting at Camp Pendleton, California. Reminiscent of a torch, a new generation of Marines was eager to prove itself worthy of the trust attendant in the acceptance of the proud colors. Even before the nucleus had been formed, still other changes were on the drawing board. In late 1965, the Commandant approved a plan to reorganize the Organized Marine Corps Reserve so that the division/wing team would become a mirror image of its regular counterparts. The first step toward achieving this goal was to reorganize the 4th Marine Aircraft Wing so that it would reflect an active wing, all of these changes were made by 15 July 1970 when Brigadier General Leo J. Dulacki arrived to take command of the division. One month later, General Dulacki was promoted to major general, the nucleus designation was dropped with the command unit now being designated as Headquarters, 4th Marine Division

Houston
–
Houston is the most populous city in the state of Texas and the fourth-most populous city in the United States. With a census-estimated 2014 population of 2.239 million within an area of 667 square miles, it also is the largest city in the southern United States and the seat of Harris County. Located in Southeast Texas near the Gulf of Mexico, it is the city of Houston–The Woodlands–Sugar Land. Houston was founded on August 28,1836, near the banks of Buffalo Bayou and incorporated as a city on June 5,1837. The city was named after former General Sam Houston, who was president of the Republic of Texas and had commanded, the burgeoning port and railroad industry, combined with oil discovery in 1901, has induced continual surges in the citys population. Houstons economy has an industrial base in energy, manufacturing, aeronautics. Leading in health care sectors and building equipment, Houston has more Fortune 500 headquarters within its city limits than any city except for New York City. The Port of Houston ranks first in the United States in international waterborne tonnage handled, the city has a population from various ethnic and religious backgrounds and a large and growing international community. Houston is the most diverse city in Texas and has described as the most diverse in the United States. It is home to cultural institutions and exhibits, which attract more than 7 million visitors a year to the Museum District. Houston has a visual and performing arts scene in the Theater District. In August 1836, two real estate entrepreneurs from New York, Augustus Chapman Allen and John Kirby Allen, purchased 6,642 acres of land along Buffalo Bayou with the intent of founding a city. The Allen brothers decided to name the city after Sam Houston, the general at the Battle of San Jacinto. The great majority of slaves in Texas came with their owners from the slave states. Sizable numbers, however, came through the slave trade. New Orleans was the center of trade in the Deep South. Thousands of enslaved African Americans lived near the city before the Civil War, many of them near the city worked on sugar and cotton plantations, while most of those in the city limits had domestic and artisan jobs. Houston was granted incorporation on June 5,1837, with James S. Holman becoming its first mayor, in the same year, Houston became the county seat of Harrisburg County and the temporary capital of the Republic of Texas

Battle of Tinian
–
The Battle of Tinian was a battle of the Pacific campaign of World War II, fought on the island of Tinian in the Mariana Islands from 24 July until 1 August 1944. The 9, 000-man Japanese garrison was eliminated, and the island joined Saipan, a two-prong attack through the Central Pacific and the Philippines was adopted at the 1943 Cairo Conference. Operation Granite II, was a U. S. Navy devised strategy of island hopping, calling for the seizure of Saipan, Tinian, the Gilbert and Marshall Islands had been seized by the summer of 1944, while some Japanese garrisons were left to starve. The US naval bombardment commenced on 16 July, with three battleships, five cruisers and sixteen destroyers, the battleship Colorado and the destroyer Norman Scott were both hit by 150mm Japanese shore batteries. Colorado was hit 22 times, killing 43 men and wounding 198, Norman Scott was hit six times, killing the captain, Seymore Owens, and 18 of his seamen, plus wounding 47. The 4th Marine Division landed on 24 July 1944, supported by naval bombardment, with the help of Seabee inginuity the Marines were able to land where the Japanese did not expect, along the Northwest coast with its waters edge small coral cliffs. A successful feint for the settlement of Tinian Town diverted defenders from the actual landing site on the north of the island. They withstood a series of night counterattacks supported by tanks, the weather worsened on 28 July, damaging the pontoon causeways, and interrupting the unloading of supplies. By 29 July, the Americans had captured half the island, Japanese remnants made a final stand in the caves and ravines of a limestone ridge on the south portion of the island, making probes and counterattacks into the Marine line. Resistance continued through 3 August, with some civilians murdered by the Japanese, by 10 August 1944,13,000 Japanese civilians were interred, but up to 4,000 were dead through suicide, murdered by Japanese troops or killed in combat. The garrison on Aguijan Island off the southwest cape of Tinian, commanded by Lieutenant Kinichi Yamada, held out until the end of the war, the last holdout on Tinian, Murata Susumu, was captured in 1953. After the battle, Tinian became an important base for further Allied operations in the Pacific campaign, camps were built for 50,000 troops. North Field was built over Airfields No.1 and 3,2, and became operational in March 1945. Four 1000-bed hospitals were planned and located in preparation for the invasion of Japan, none were actually built, as the Japanese surrendered after the atomic bombs were dropped, which thus ended the need for the hospitals.

Battle of Saipan
–
The Battle of Saipan was a battle of the Pacific campaign of World War II, fought on the island of Saipan in the Mariana Islands from 15 June to 9 July 1944. The Allied invasion fleet embarking the expeditionary forces left Pearl Harbor on 5 June 1944, in the campaigns of 1943 and the first half of 1944, the Allies had captured the Solomon Islands, the Gilbert Islands, the Marshall Islands and the Papuan Peninsula of New Guinea. This left the Japanese holding the Philippines, the Caroline Islands, Palau Islands and it had always been the intention of the American planners to bypass the Carolines and Palauan islands and to seize the Marianas and Taiwan. From these latter bases, communications between the Japanese archipelago and Japanese forces to the south and west could be cut. From the Marianas, Japan would be well within the range of an air offensive relying on the new Boeing B-29 Superfortress long-range bomber with its radius of 1,500 mi. The Japanese, expecting an attack somewhere on their perimeter, thought an attack on the Caroline Islands most likely, to reinforce and supply their garrisons, they needed naval and air superiority, so Operation A-Go, a major carrier attack, was prepared for June 1944. Smith XXIV Corps Artillery — Brigadier General Arthur M. Harper 1st Provisional Gun Group 225th Field Artillery Howitzer Group 2nd Marine Division — Major General Thomas E, fifteen battleships were involved, and 165,000 shells were fired. Seven modern fast battleships delivered 2,40016 in shells, but to avoid potential minefields, fire was from a distance of 10,000 yd or more, the following day the eight older battleships and 11 cruisers under Admiral Jesse B. Oldendorf replaced the fast battleships but were lacking in time and ammunition, the landings began at 07,00 on 15 June 1944. More than 300 LVTs landed 8,000 Marines on the west coast of Saipan by about 09,00, eleven fire support ships covered the Marine landings. However, by nightfall, the 2nd and 4th Marine Divisions had a beachhead about 6 mi wide and 0.5 mi deep, the Japanese counter-attacked at night but were repulsed with heavy losses. On 16 June, units of the U. S. Armys 27th Infantry Division landed and advanced on the airfield at Ås Lito, again the Japanese counter-attacked at night. On 18 June, Saito abandoned the airfield, the invasion surprised the Japanese high command, which had been expecting an attack further south. Admiral Soemu Toyoda, Commander-in-Chief of the Japanese Navy, saw an opportunity to use the A-Go force to attack the U. S. Navy forces around Saipan, on 15 June, he gave the order to attack. But the resulting battle of the Philippine Sea was a disaster for the Imperial Japanese Navy, the garrisons of the Marianas would have no hope of resupply or reinforcement. Without resupply, the battle on Saipan was hopeless for the defenders, Saito organized his troops into a line anchored on Mount Tapotchau in the defensible mountainous terrain of central Saipan. The nicknames given by the Americans to the features of the battle — Hells Pocket, Purple Heart Ridge, the Japanese used the many caves in the volcanic landscape to delay the attackers, by hiding during the day and making sorties at night. The Americans gradually developed tactics for clearing the caves by using flamethrower teams supported by artillery, however, General Holland Smith had not inspected the terrain over which the 27th was to advance

Battle of Iwo Jima
–
The Battle of Iwo Jima was a major battle in which the United States Marine Corps landed on and eventually captured the island of Iwo Jima from the Japanese Imperial Army during World War II. This five-week battle comprised some of the fiercest and bloodiest fighting of the War in the Pacific of World War II, after the heavy losses incurred in the battle, the strategic value of the island became controversial. It was useless to the U. S. Army as a staging base, however, Navy Seabees rebuilt the landing strips, which were used as emergency landing strips for USAAF B-29s. The Imperial Japanese Army positions on the island were heavily fortified, with a network of bunkers, hidden artillery positions. The American ground forces were supported by naval artillery, and had complete air supremacy provided by U. S. Navy. Japanese combat deaths numbered three times the number of American deaths, although uniquely among Pacific War Marine battles, American total casualties exceeded those of the Japanese. Of the 21,000 Japanese soldiers on Iwo Jima at the beginning of the battle, only 216 were taken prisoner, despite the bloody fighting and severe casualties on both sides, the Japanese defeat was assured from the start. Joe Rosenthals Associated Press photograph of the raising of the U. S. flag on top of the 169 m Mount Suribachi by six U. S, Marines became an iconic image of the battle and the American war effort in the Pacific. All indications pointed to an American drive toward the Mariana Islands, in March 1944, the Japanese 31st Army, commanded by General Hideyoshi Obata, was activated to garrison this inner line. The commander of the Japanese garrison on Chichi Jima was placed nominally in command of Army, after the American conquest of the Marianas, daily bomber raids from the Marianas hit the mainland as part of Operation Scavenger. Iwo Jima served as an early warning station that radioed reports of incoming bombers back to mainland Japan and this allowed Japanese air defenses to prepare for the arrival of American bombers. At the same time, with reinforcements arriving from Chichi Jima and the home islands, in addition, it was used by the Japanese to stage air attacks on the Mariana Islands from November 1944 through January 1945. The capture of Iwo Jima would eliminate these problems and provide an area for Operation Downfall – the eventual invasion of the Japanese Home Islands. The distance of B-29 raids could be cut in half, American intelligence sources were confident that Iwo Jima would fall in one week. In light of the intelligence reports, the decision was made to invade Iwo Jima. American forces were unaware that the Japanese were preparing a complex and deep defense, by June 1944, Lieutenant General Tadamichi Kuribayashi was assigned to command the defense of Iwo Jima. While drawing inspiration from the defense in the Battle of Peleliu, takeichi Nishis armored tanks were to be used as camouflaged artillery positions. This network of bunkers and pillboxes favored the defense, for instance, The Nanpo Bunker, which was located east of Airfield Number 2, had enough food, water and ammo for the Japanese to hold out for three months

Gulf War
–
The Iraqi Armys occupation of Kuwait that began 2 August 1990 was met with international condemnation, and brought immediate economic sanctions against Iraq by members of the UN Security Council. US President George H. W. Bush deployed US forces into Saudi Arabia, an array of nations joined the coalition, the largest military alliance since World War II. The great majority of the military forces were from the US, with Saudi Arabia, the United Kingdom. Kuwait and Saudi Arabia paid around US$32 billion of the US$60 billion cost, the war was marked by the introduction of live news broadcasts from the front lines of the battle, principally by the US network CNN. The war has also earned the nickname Video Game War after the daily broadcast of images from cameras on board US bombers during Operation Desert Storm. The initial conflict to expel Iraqi troops from Kuwait began with an aerial and naval bombardment on 17 January 1991 and this was followed by a ground assault on 24 February. This was a victory for the coalition forces, who liberated Kuwait. The coalition ceased its advance, and declared a ceasefire 100 hours after the campaign started. Aerial and ground combat was confined to Iraq, Kuwait, Iraq launched Scud missiles against coalition military targets in Saudi Arabia and against Israel. The following names have been used to describe the conflict itself, Gulf War, a problem with these terms is that the usage is ambiguous, having now been applied to at least three conflicts, see Gulf War. The use of the term Persian Gulf is also disputed, see Persian Gulf naming dispute, with no consensus of naming, various publications have attempted to refine the name. Other language terms include French, la Guerre du Golfe and German, Golfkrieg, German, Zweiter Golfkrieg, French, most of the coalition states used various names for their operations and the wars operational phases. Operation Desert Storm was the US name of the conflict from 17 January 1991. Operation Desert Sabre was the US name for the offensive against the Iraqi Army in the Kuwaiti Theater of Operations from 24–28 February 1991, in itself. Operation Desert Farewell was the given to the return of US units and equipment to the US in 1991 after Kuwaits liberation. Operation Granby was the British name for British military activities during the operations, Opération Daguet was the French name for French military activities in the conflict. Operation Friction was the name of the Canadian operations Operazione Locusta was the Italian name for the operations, in addition, various phases of each operation may have a unique operational name. The US divided the conflict into three campaigns, Defense of Saudi Arabian country for the period 2 August 1990, through 16 January 1991

Infantry
–
Infantry is the general branch of an army that engages in military combat on foot. As the troops who engage with the enemy in close-ranged combat, infantry units bear the largest brunt of warfare, Infantry can enter and maneuver in terrain that is inaccessible to military vehicles and employ crew-served infantry weapons that provide greater and more sustained firepower. In English, the 16th-century term Infantry describes soldiers who walk to the battlefield, and there engage, fight, the term arose in Sixteenth-Century Spain, which boasted one of the first professional standing armies seen in Europe since the days of Rome. It was common to appoint royal princes to military commands, and the men under them became known as Infanteria. in the Canadian Army, the role of the infantry is to close with, and destroy the enemy. In the U. S. Army, the closes with the enemy, by means of fire and maneuver, in order to destroy or capture him, or to repel his assault by fire, close combat. In the U. S. Marine Corps, the role of the infantry is to locate, close with, and destroy the enemy fire and maneuver. Beginning with the Napoleonic Wars of the early 19th century, artillery has become a dominant force on the battlefield. Since World War I, combat aircraft and armoured vehicles have become dominant. In 20th and 21st century warfare, infantry functions most effectively as part of a combined arms team including artillery, armour, Infantry relies on organized formations to be employed in battle. These have evolved over time, but remain a key element to effective infantry development and deployment, until the end of the 19th century, infantry units were for the most part employed in close formations up until contact with the enemy. This allowed commanders to control of the unit, especially while maneuvering. The development of guns and other weapons with increased firepower forced infantry units to disperse in order to make them less vulnerable to such weapons. This decentralization of command was made possible by improved communications equipment, among the various subtypes of infantry is Medium infantry. This refers to infantry which are heavily armed and armored than heavy infantry. In the early period, medium infantry were largely eliminated due to discontinued use of body armour up until the 20th century. In the United States Army, Stryker Infantry is considered Medium Infantry, since they are heavier than light infantry, Infantry doctrine is the concise expression of how infantry forces contribute to campaigns, major operations, battles, and engagements. It is a guide to action, not a set of hard, doctrine provides a very common frame of reference across the military forces, allowing the infantry to function cooperatively in what are now called combined arms operations. Doctrine helps standardise operations, facilitating readiness by establishing common ways of accomplishing infantry tasks, doctrine links theory, history, experimentation, and practice

Texas
–
Texas is the second largest state in the United States by both area and population. Other major cities include Austin, the second most populous state capital in the U. S. Texas is nicknamed the Lone Star State to signify its former status as an independent republic, and as a reminder of the states struggle for independence from Mexico. The Lone Star can be found on the Texan state flag, the origin of Texass name is from the word Tejas, which means friends in the Caddo language. Due to its size and geologic features such as the Balcones Fault, although Texas is popularly associated with the U. S. southwestern deserts, less than 10 percent of Texas land area is desert. Most of the centers are located in areas of former prairies, grasslands, forests. Traveling from east to west, one can observe terrain that ranges from coastal swamps and piney woods, to rolling plains and rugged hills, the term six flags over Texas refers to several nations that have ruled over the territory. Spain was the first European country to claim the area of Texas, Mexico controlled the territory until 1836 when Texas won its independence, becoming an independent Republic. In 1845, Texas joined the United States as the 28th state, the states annexation set off a chain of events that caused the Mexican–American War in 1846. A slave state before the American Civil War, Texas declared its secession from the U. S. in early 1861, after the Civil War and the restoration of its representation in the federal government, Texas entered a long period of economic stagnation. One Texan industry that thrived after the Civil War was cattle, due to its long history as a center of the industry, Texas is associated with the image of the cowboy. The states economic fortunes changed in the early 20th century, when oil discoveries initiated a boom in the state. With strong investments in universities, Texas developed a diversified economy, as of 2010 it shares the top of the list of the most Fortune 500 companies with California at 57. With a growing base of industry, the leads in many industries, including agriculture, petrochemicals, energy, computers and electronics, aerospace. Texas has led the nation in export revenue since 2002 and has the second-highest gross state product. The name Texas, based on the Caddo word tejas meaning friends or allies, was applied by the Spanish to the Caddo themselves, during Spanish colonial rule, the area was officially known as the Nuevo Reino de Filipinas, La Provincia de Texas. Texas is the second largest U. S. state, behind Alaska, though 10 percent larger than France and almost twice as large as Germany or Japan, it ranks only 27th worldwide amongst country subdivisions by size. If it were an independent country, Texas would be the 40th largest behind Chile, Texas is in the south central part of the United States of America. Three of its borders are defined by rivers, the Rio Grande forms a natural border with the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south
