The Quartermaster Corps is the U.S. Army's oldest logistics branch, established 16 June 1775. On that date, the Second Continental Congress passed a resolution providing for "one Quartermaster General of the grand army and a deputy, under him, for the separate army". From 1775 to 1912, this organization was known as the Quartermaster Department. In 1912, Congress consolidated the former Subsistence, Pay, and Quartermaster Departments to create the Quartermaster Corps. Quartermaster units and soldiers have served in every U.S. military operation from the Revolutionary War to current operations in Iraq (Operation Iraqi Freedom) and Afghanistan (Operation Enduring Freedom)
