Fort Knox is a United States Army installation in Kentucky, south of Louisville and north of Elizabethtown. It is adjacent to the United States Bullion Depository, which is used to house a large portion of the United States' official gold reserves, and with which it is often conflated. The base covers parts of Bullitt, Hardin and Meade counties. It currently holds the Army Human Resources Center of Excellence, including the Army Human Resources Command. It is named in honor of Henry Knox, Chief of Artillery in the American Revolutionary War and the first United States Secretary of War. For 60 years, Fort Knox was the home of the U.S. Army Armor Center and the U.S. Army Armor School, and was used by both the Army and the Marine Corps to train crews on the American tanks of the day; the last was the M1 Abrams main battle tank. The history of the U.S. Army's Cavalry and Armored forces, and of General George S. Patton's career, is shown at the General George Patton Museum on the grounds of Fort Knox. In 2011, the U.S. Army Armor School moved to Fort Benning, Georgia, where the Infantry School is also based. In 2014, the U.S. Army Cadet Command relocated to Fort Knox and all summer training for ROTC cadets now takes place there. On 16 October 2020, V Corps was reactivated at Fort Knox, just over seven years after the colors were last cased in Wiesbaden, Germany in July 2013. Bullion depository The United States Bullion Depository, often known as Fort Knox, is a fortified vault building adjacent to the Fort Knox Army Post. It is operated by the United States Department of the Treasury and stores over half the country's gold reserves. It is protected by the United States Mint Police and is well known for its physical security. The depository was built by the Treasury in 1936 on land transferred to it from Fort Knox. Early shipments of gold totaling almost 13,000 metric tons were escorted by combat cars of the 1st U.S. Cavalry Regiment to the depository. It has in the past safeguarded other precious items, such as the original copies of both the Constitution of the United States and the United States Declaration of Independence. Census-designated place Parts of the base in Hardin and Meade counties form a census-designated place (CDP), which had a population of 12,377 at the
