Defense Acquisition University
The Defense Acquisition University is a corporate university of the United States Department of Defense offering "acquisition and logistics" training to military and Federal civilian staff and Federal contractors. DAU is headquartered in Fort Belvoir, is accredited by the American Council on Education, International Association for Continuing Education and Training and the Council on Occupational Education; the University Charter was created in October 1991 by Department of Defense Directive 5000.57. A loose consortium of existing training commands, DAU worked to standardize the training courses and establish mechanisms that allowed for centralized management of training funds for the DoD workforce. In the late 1990s, the consortium arrangement was replaced by a centralized structure, more like that of a corporate university. By 2014, DAU had grown to the point of graduating 181,970 students. DAU was headed by a Commandant until the year 2000 when it became a civilian institution, since the chief executive position has the title "President."
DAU's Commandants and Presidents have included William L. Vincent, Claude M. Bolton, Richard A. Black, Leonard Vincent, Frank J. Anderson, Katrina McFarland, James P. Woolsey. DAU is headquartered at Fort Belvoir and serves 150,000 members of the defense acquisition workforce in all. DAU has several other locations across the United States as well an online presence; the Capital and Northeast Region campus is located at Fort Belvoir and provides access and services to The Pentagon and Washington Department of Defense agencies. It is the biggest facility. Other facilities include DAU Mid-Atlantic, located in California, Maryland, DAU South, in Huntsville, Alabama, DAU Midwest, located in Kettering, DAU West in San Diego. Various satellite locations are located to provide classes for major military commands. Applicants must have a current affiliation with the United States government in order to attend training courses offered by DAU; the United States Military Services and the DoD have internal registration and quotas for DAU class, while the Federal Acquisition Institute accepts applications and registers most non-DoD students.
U. S. Federal employees and defense contractors may attend DAU courses at no cost when space is available. DAU charges tuition only to certain foreign students; the Defense Acquisition Workforce Improvement Act requires Defense Acquisition Workforce members to be certified for the positions they hold. DAU offers training courses for all Defense Acquisition Workforce members in 14 career fields and at three certification levels. Certifications available: The American Council on Education assigns ACE credits to various DAU courses. DAU coursework can apply toward college and university degrees and certificates at some partner institutions. DAU instructors are available to consult and assist acquisition organizations in the design and review of processes and internal training when they are not teaching. On July 2011 a hacking incident occurred affecting DAU’s Web-based training site; this incident occurred on a vendor’s network that provided the learning management system's underlying source code and inhibited access to online courses for two months.
While DAU was not hacked, U. S. Cyber Command evaluated the risk level to DAU’s system based on the incident that occurred on the vendor’s network, temporarily suspended online training courses to secure the system and protect students' personal information.

29th Infantry Division (United States)
The 29th Infantry Division known as the "Blue and Gray", is an infantry division of the United States Army based in Fort Belvoir, Virginia. It is a formation of the U. S. Army National Guard and contains units from Virginia, Kentucky, North Carolina, West Virginia. Formed in 1917, the division deployed to France as a part of the American Expeditionary Force during World War I. Called up for service again in World War II, the division's 116th Regiment, attached to the First Infantry Division, was in the first wave of troops ashore during Operation Overlord, the landings in Normandy, France, it supported a special Ranger unit tasked with clearing strong points at Omaha Beach. The rest of the 29th ID came ashore then advanced to Saint-Lô, through France and into Germany itself. Following the end of World War II, the division saw frequent deactivations. Although the 29th did not see combat through most of the next 50 years, it participated in numerous training exercises throughout the world, it saw deployments to Bosnia and Kosovo as command elements, units of the division continue to deploy to locations such as Guantanamo Bay Naval Base and to the War in Afghanistan as a part of the Global War on Terrorism's Operation Enduring Freedom, to the Iraq War, as a part of its Operation Iraqi Freedom and Operation New Dawn.
In 2016, two separate elements of the 29th deployed overseas. In July more than 80 soldiers deployed in support of anti-ISIL operations. In October, more than 450 29th soldiers deployed in support of Operation Spartan Shield; the 29th Division was first constituted on paper 18 July 1917, three months after the American entry into World War I, in the U. S. Army National Guard; the division's infantry units were the 57th Infantry Brigade, made up of the 113th and 114th Infantry Regiments, both from New Jersey, the 58th Infantry Brigade, made up of the 115th Infantry Regiment from Maryland and 116th Infantry Regiment from Virginia. Its artillery units were Maryland's 110th Artillery Regiment; as the division was composed of men from states that had units that fought for both the North and South during the Civil War, it was nicknamed the "Blue and Gray" division, after the blue uniforms of the Union and the gray uniforms of the Confederate armies during the American Civil War. The division was organized on 25 August 1917 at Camp McClellan, Alabama.
The division departed for the Western Front in June 1918 to join the American Expeditionary Force. The division's advance detachment reached France on 8 June. In late September, the 29th received orders to join the U. S. First Army's Meuse-Argonne Offensive as part of the French XVII Corps. During its 21 days in combat, the 29th Division advanced seven kilometers, captured 2,148 prisoners, knocked out over 250 machine guns or artillery pieces. Thirty percent of the division became casualties—170 officers and 5,691 enlisted men were killed or wounded. Shortly thereafter the Armistice with Germany was signed on November 11, 1918, ending hostilities between the Central Powers and the Allied Powers; the division returned to the United States in May 1919. It demobilized on 30 May at New Jersey, though it remained an active National Guard unit.

S. Army began reorganization of its fighting forces; the division was called into active service on 3 February 1941. Elements of the division were sent to Fort Meade, Maryland for training; the 57th and 58th Infantry Brigades were inactivated as part of an army-wide removal of brigades from divisions. Instead, the core units of the division were its three infantry regiments, along with supporting units. On 12 March 1942, over three months after the Japanese attack on Pearl Harbor and the subsequent American entrance into World War II, with this reorganization complete the division was redesignated as the 29th Infantry Division and began preparing for overseas deployment to Europe.

United States Armed Forces
The United States Armed Forces are the military forces of the United States of America. It consists of the Army, Marine Corps, Air Force, Coast Guard; the President of the United States is the Commander-in-Chief of the Armed Forces and forms military policy with the Department of Defense and Department of Homeland Security, both federal executive departments, acting as the principal organs by which military policy is carried out. All five armed services are among the seven uniformed services of the United States. From the time of its inception, the U. S. Armed Forces played a decisive role in the history of the United States. A sense of national unity and identity was forged as a result of victory in the First Barbary War and the Second Barbary War. So, the founders of the United States were suspicious of a permanent military force, it played a critical role in the American Civil War, continuing to serve as the armed forces of the United States, although a number of its officers resigned to join the military of the Confederate States.
The National Security Act of 1947, adopted following World War II and during the Cold War's onset, created the modern U. S. military framework. The Act established the National Military Establishment, headed by the Secretary of Defense, it was amended in 1949, renaming the National Military Establishment the Department of Defense, merged the cabinet-level Department of the Army, Department of the Navy, Department of the Air Force, into the Department of Defense. The U. S. Armed Forces are one of the largest militaries in terms of the number of personnel, it draws its personnel from a large pool of paid volunteers. Although conscription has been used in the past in various times of both war and peace, it has not been used since 1973, but the Selective Service System retains the power to conscript males, requires that all male citizens and residents residing in the U. S. between the ages of 18–25 register with the service. On February 22, 2019, however, a federal judge ruled that registering only males for Selective Service is unconstitutional.
As of 2017, the U. S. spends about US$610 billion annually to fund its military forces and Overseas Contingency Operations. Put together, the U. S. constitutes 40 percent of the world's military expenditures. The U. S. Armed Forces has significant capabilities in both defense and power projection due to its large budget, resulting in advanced and powerful technologies which enables a widespread deployment of the force around the world, including around 800 military bases outside the United States; the U. S. Air Force is the world's largest air force, the U. S. Navy is the world's largest navy by tonnage, the U. S. Navy and the U. S. Marine Corps combined are the world's second largest air arm. In terms of size, the U. S. Coast Guard is the world's 12th largest naval force; the history of the U. S. Armed Forces dates to 14 June 1775, with the creation of the Continental Army before the Declaration of Independence marked the establishment of the United States; the Continental Navy, established on 13 October 1775, Continental Marines, established on 10 November 1775, were created in close succession by the Second Continental Congress in order to defend the new nation against the British Empire in the American Revolutionary War.
These forces demobilized in 1784. The Congress of the Confederation created the current United States Army on 3 June 1784; the United States Congress created the current United States Navy on 27 March 1794 and the current United States Marine Corps on 11 July 1798. All three services trace their origins to their respective Continental predecessors; the 1787 adoption of the Constitution gave the Congress the power to "raise and support armies", to "provide and maintain a navy" and to "make rules for the government and regulation of the land and naval forces", as well as the power to declare war. The President is the U. S. Armed Forces' commander-in-chief; the United States Coast Guard traces its origin to the founding of the Revenue Cutter Service on 4 August 1790 which merged with the United States Life-Saving Service on 28 January 1915 to establish the Coast Guard. The United States Air Force was established as an independent service on 18 September 1947. S. Signal Corps, formed 1 August 1907 and was part of the Army Air Forces before becoming an independent service as per the National Security Act of 1947.
The United States Public Health Service Commissioned Corps was considered to be a branch of the United States Armed Forces from 29 July 1945 until its status as such was revoked on 3 July 1952. On March 1st, 2019, the Department of Defense sent a proposal to Congress that would establish the United States Space Force as an independent military service within the Department of the Air Force. If approved, this would become the sixth military service branch to be created. Command over the U. S. Armed Forces is established in the Constitution; the sole power of command is vested in the President by Article II as Commander-in-Chief. The Constitution presumes the existence of "executive Departments" headed by "principal officers", whose appointment mechanism is provided for in the Appointments Clause; this allowance in the Constitution formed the basis for creation of the Department of Defense in 1947 by the National Security Act. The DoD is headed by the Secretary of Defense, a civilian and member of the Cabinet.
The Defense Secretary is second in the U. S. Armed Forces chain of command, with the exception of the Coast Guard, under the Secretary of Homeland Security, is just below the President and serves as the
Fairfax County, Virginia
Fairfax County the County of Fairfax is a county of the Commonwealth of Virginia in the United States. Part of Northern Virginia, Fairfax County borders both the City of Alexandria and Arlington County and forms part of the inner suburban ring of Washington, DC; the county is thus predominantly suburban with some urban and rural pockets. As of the 2010 census, the population was 1,081,726, in 2015, it was estimated at 1,142,234, making it the Commonwealth's most populous jurisdiction, with 13.6% of Virginia's population. The county is the most populous jurisdiction in the Washington-Arlington-Alexandria, DC-VA-MD-WV Metropolitan Statistical Area, with 19.8% of the MSA population, as well as the larger Washington-Baltimore-Arlington, DC-MD-VA-WV-PA Combined Statistical Area, with 13.1% of the CSA population. The county seat is the City of Fairfax, though because it is an independent city under Virginia law, the city of Fairfax is not part of Fairfax County. Fairfax was the first U. S. county to reach a six-figure median household income and has the second-highest median household income of any county-level local jurisdiction in the United States after neighbor Loudoun County.
The county is home to the headquarters of intelligence agencies such as the Central Intelligence Agency, National Geospatial-Intelligence Agency, National Reconnaissance Office, as well as the National Counterterrorism Center and Office of the Director of National Intelligence. The county is home to seven Fortune 500 companies, including three with Falls Church addresses. At the time of European encounter, the inhabitants of what would become Fairfax County were an Algonquian-speaking sub-group called the Taux known as the Doeg or Dogue, their villages, as recorded by Captain John Smith in 1608, included Namassingakent and Nemaroughquand on the south bank of the Potomac River in what is now Fairfax County. Virginian colonists from the Northern Neck region drove the Doeg out of this area and into Maryland by 1670. Fairfax County was formed in 1742 from the northern part of Prince William County, it was named for 6th Lord Fairfax of Cameron, proprietor of the Northern Neck. The Fairfax family name is derived from the Old English phrase for "blond hair" – Fæger-feax.
The oldest settlements in Fairfax County were along the Potomac River. George Washington built his home, Mount Vernon, facing the river. Gunston Hall, the home of George Mason is nearby. Modern Fort Belvoir is on the estate of Belvoir Manor, built along the Potomac by William Fairfax in 1741. Thomas Fairfax, 6th Lord Fairfax of Cameron, the only member of the British nobility to reside in the colonies, lived at Belvoir before he moved to the Shenandoah Valley; the Belvoir mansion and several of its outbuildings were destroyed by fire after the Revolutionary War in 1783, George Washington noted the plantation complex deteriorated into ruins. In 1757, the northwestern two-thirds of Fairfax County became Loudoun County. In 1789, part of Fairfax County was ceded to the federal government to form Alexandria County of the District of Columbia. Alexandria County was returned to Virginia in 1846, reduced in size by the secession of the independent city of Alexandria in 1870, renamed Arlington County in 1920.
The Fairfax County town of Falls Church became an independent city in 1948. The Fairfax County town of Fairfax became an independent city in 1961. Located near Washington, D. C. Fairfax County was an important region in the Civil War; the Battle of Chantilly or Ox Hill, during the same campaign as the second Battle of Bull Run, was fought within the county. Other areas of activity included Minor's Hill, Munson's Hill, Upton's Hill, on the county's eastern border, overlooking Washington, D. C; the federal government's growth during and after World War II spurred rapid growth in the county and made the county suburban. Other large businesses continued to settle in Fairfax County and the opening of Tysons Corner Center spurred the rise of Tysons Corner; the technology boom and a steady government-driven economy created rapid growth and an growing and diverse population. The economy has made Fairfax County one of the nation's wealthiest counties. A general aviation airport located along U. S. Route 50, west of Seven Corners called the Falls Church Airpark operated in the county from 1948 to 1960.
The facility's 2,650 foot unpaved runway was used extensively by private pilots and civil defense officials. Residential development, multiple accidents, the demand for retail space led to its closure in 1960. According to the U. S. Census Bureau, the county has a total area of 406 square miles, of which 391 square miles is land and 15 square miles is water. Fairfax County is bounded on the southeast by the Potomac River. Across the river to the northeast is Washington, D. C. across the river to the north is Montgomery County and across the river to the southeast are Prince George's County and Charles County, Maryland. The county is bounded on the north and east by Arlington County and the independent cities of Alexandria and Falls Church, it is bounded on the west by Loudoun County, on the south by Prince William County. Most of the county lies in the Piedmont region, with rolling hills and deep stream valleys such as Difficult Run and its tributaries. West of Route 28, the hills give way to a flat, gentle valley which stretches west to the Bull Run Mountains in Loudoun County.
Elevations in the county range from near sea level along the tidal sections of the Potomac River in the southeast port

S. Army Corps of Engineers support to presidentially declared disasters The 249th Engineer Combat Battalion was constituted on 5 May 1943 at Camp Bowie, Texas; the battalion was organized and under the command of only three captains. The other officers that were supplied to the unit were second lieutenants from the 1943 class of West Point. Shortly after, the battalion participated in two maneuvers in Louisiana, known as the "Louisiana Maneuvers"; the 249th sailed from the United States to England in May 1944, after equipping and preparing for combat, the Unit landed on Utah Beach in August 1944 under the 1137th Engineer Combat Group commanded by Colonel George A. Morris. In October through November 1944, the soldiers were specially trained on using the Bailey bridge in Trier, France.
That year on 18 December 1944, the Black Lions were ordered to move from the Saar River, where the unit was building a bridge, to the Ardennes called the Battle of the Bulge. Upon arriving to the front, the 249th was assigned to the 26th Infantry Division engaged and in defensive positions along the southeast corner of the Bulge; the battalion was used in an effort to block the German advance by deploying landmines and establishing roadblocks. On 24 December 1944, Brigadier General Harlan Harkness, the assistant division commander, ordered the battalion to advance and secure the towns of Arsdorf and Bigonville to the north of the 26th Infantry Division, near the area of operations of the 4th Armored Division, in order to relieve the occupied towns so the division could advance and attack the enemy line. Companies A and C were ordered into the town of Arsdorf where the battalion was engaged in fierce combat for two days, it was learned that the town had never been secured by the 4th Armored Division.
In February 1945, the battalion was selected for the special task of crossing the Rhine River. On 19 March 1945, the unit was assigned to the engineer task force charged with crossing the Rhine at Oppenheim; the main thrust of the effort was to use assault boats to get troops from 5th Infantry Division across and to construct a more stable pontoon bridge. The battalion met little resistance across the river and began constructing the bridge. After an accident resulting in a raft being sunk, the Battalion moved downriver to Mainz. After this bridge site was secure, the 249th was detached from the 1137th Engineer Group and was given the mission to secure and maintain the bridges on the Rhine River. In May 1945, when the war ended in Europe, the battalion was moved to Plattling, Germany where they built a camp for displaced refugees. In November 1945, the 249th Engineers were sent on their final orders to Camp Lucky Strike, near Marseilles and redeployed back to the United States; the division was inactivated at Camp Patrick Henry, Virginia on 27 November 1945.
In late 1954, the Black Lion Battalion was withdrawn from the Reserves and assigned to the Regular Army. In February 1955, it was assigned to USAREUR and an Engineer Battalion. From 1955 until 1960, the 249th Engineer Battalion was stationed at Kleber Kaserne, it was dispatched to France for a time. The battalion was stationed at Gerszewski Barracks, Karlsruhe, under the command of the 18th Engineer Brigade, where it provided construction support to USAREUR elements stationed in Germany for the Cold War. In 1994, the battalion was reactivated and designated as the 249th Engineer Battalion, stationed at Fort Belvoir, VA. After the attacks on the World Trade Center on 11 September 2001, elements of the 249th were deployed to New York City and were instrumental in restoring power to Wall Street enabling the financial district to resume operations within a week of the attack; the 249th Engineer Battalion provides oversight on all coalition operating base power projects in Iraq and Afghanistan. The 249th deployed teams to the Gulf Region under Joint Task Force Katrina, working with contractors, local and state entities to assess, they helped install and maintain emergency generators at critical facilities.

Fort Leonard Wood
Fort Leonard Wood is a U. S. Army training installation located in the Missouri Ozarks; the main gate is located on the southern boundary of St. Robert; the post was created in December 1940 and named in honor of General Leonard Wood in January 1941. Intended to train infantry troops, in 1941 it became an engineer training post with the creation of the Engineer Replacement Training Center. During World War II Italian and German POWs were interned at the fort. In 1984, as part of the Base Realignment and Closure process, most of the U. S. Army Engineer School's operations were consolidated at Fort Leonard Wood. Before that, officer training was conducted at Virginia. In 1999, again as part of the Base Realignment and Closure process, Fort McClellan, Alabama was closed, the U. S. Army Chemical Corps and Military Police Corps schools were transferred to Fort Leonard Wood, concurrently redesignated the U. S. Army Maneuver Support Center. In 2009, the U. S. Army Maneuver Support Center was redesignated the U.
S. Army Maneuver Support Center of Excellence. S. Army training institutions; the current commanding general is Major General Donna Martin and the command sergeant major is Command Sergeant Major James Breckinridge. Prior to the establishment of the current Fort Leonard Wood, the same name was used in 1928 to rename Camp Meade in central Maryland when it was decided that Camp Meade established as a temporary WWI cantonment, would become a permanent military base. However, after a brief time the change of name was challenged by US legislators from Pennsylvania where George G. Meade hero of Gettysburg was from and the name was changed to Ft. Meade; this left the name Leonard Wood unused and available for when the current base was built in 1941. The installation has had a training role under TRADOC rather than a FORSCOM role dating back to its origins in World War II as an engineer replacement training post. During the Gulf War, the 5th Engineer Battalion from the fort saw action in the Middle East.
After the beginning of the current wars in Iraq and Afghanistan, the 94th Engineer Battalion was restationed from Germany to Fort Leonard Wood, as were the 92nd Military Police Battalion, 193rd Brigade Support Battalion, 94th Signal Company. The 4th Maneuver Enhancement Brigade was activated at the fort on 2 October 2008 and was inactivated June 17, 2015. Fort Leonard Wood is located at 37°44′17″N 92°7′2″W.

The Pentagon, in Arlington County, across the Potomac River from Washington, D. C. is the headquarters of the United States Department of Defense. As a symbol of the U. S. military, the phrase The Pentagon is used as a metonym for the Department of Defense and its leadership. The building was designed by American architect George Bergstrom and built by contractor John McShain. Ground was broken on September 11, 1941, the building was dedicated on January 15, 1943. General Brehon Somervell provided the major motivating power behind the project. S. Army; the Pentagon is the world's largest office building, with about 6,500,000 sq ft of space, of which 3,700,000 sq ft are used as offices.

The central five-acre pentagonal plaza is nicknamed "ground zero" on the presumption that it would be a prime target in a nuclear war.
On September 11, 2001 60 years after the building's construction began, American Airlines Flight 77 was hijacked and flown into the western side of the building, killing 189 people, according to the 9/11 Commission Report. It was the first significant foreign attack on Washington's governmental facilities since the city was burned by the British during the War of 1812; the Pentagon is listed on the National Register of Historic Places and is a National Historic Landmark. The Pentagon building spans 28.7 acres, includes an additional 5.1 acres as a central courtyard. Starting with the north side and moving clockwise, its five façades are the Mall Terrace Entrance façade, the River Terrace Entrance façade, the Concourse Entrance façade, the South Parking Entrance façade, the Heliport façade. On the north side of the building, the Mall Entrance, which features a portico, leads out to a 600 ft long terrace, used for ceremonies; the River Entrance, which features a portico projecting out 20 ft, is on the northeast side, overlooking the lagoon and facing Washington.
A stepped terrace on the River Entrance leads down to the lagoon. The main entrance for visitors is on the southeast side, as are the Pentagon Metro station and the bus station. There is a concourse on the southeast side of the second floor of the building, which contains a mini-shopping mall; the south parking lot adjoins the southwest facade, the west side of the Pentagon faces Washington Boulevard. The concentric rings are designated from the center out as "A" through "E". "E" Ring offices are the only ones with outside views and are occupied by senior officials. Office numbers go clockwise around each of the rings, have two parts: a nearest-corridor number followed by a bay number, so office numbers range from 100 to 1099; these corridors radiate out from the central courtyard, with corridor 1 beginning with the Concourse's south end. Each numbered radial corridor intersects with the corresponding numbered group of offices. There are a number of historical displays in the building in the "A" and "E" rings.
Floors in the Pentagon are lettered "B" for Basement and "M" for Mezzanine, both of which are below ground level. The concourse is on the second floor at the Metro entrance. Above ground floors are numbered 1 to 5. Room numbers are given as the floor, concentric ring, office number. Thus, office 2B315 is on the second floor, B ring, nearest to corridor 3. One way to get to this office would be to go to the second floor, get to the A ring, go to and take corridor 3, turn left on ring B to get to bay 15, it is possible for a person to walk between any two points in the Pentagon in less than seven minutes. The complex includes eating and exercise facilities, meditation and prayer rooms. Tours for the public were suspended after the 2001 attack. Just south of the Pentagon are Pentagon City and Crystal City, extensive shopping and high-density residential districts in Arlington. Arlington National Cemetery is to the north; the Pentagon is surrounded by the complex Pentagon road network. The Pentagon has six Washington, DC ZIP Codes.
The Secretary of Defense, the Joint Chiefs of Staff, the four service branches each have their own ZIP Code. Before the Pentagon was built, the United States Department of War was headquartered in the Munitions Building, a temporary structure erected during World War I along Constitution Avenue on the National Mall; the War Department, a civilian agency created to administer the U. S. Army, was spread out in additional temporary buildings on the National Mall, as well as dozens of other buildings in Washington, D. C. Maryland and Virginia. In the late 1930s, a new War Department Building was constructed at 21st and C Streets in Foggy Bottom but, upon completion, the new building did not solve the department's space problem and ended up being used by the Department of State; when World War II broke out in Europe, the War Department expanded in anticipation that the United States would be drawn into the conflict.
