History

Origins trace to the Continental Army established during the American Revolutionary War and to institutions of the War Department (United States). Post-World War II reforms following the National Security Act of 1947 and debates in the United States Congress transformed the organizational framework, influenced by lessons from the Battle of Midway, D-Day, and the Korean War. Cold War challenges such as the Berlin Airlift, the Vietnam War, and the Cuban Missile Crisis drove force realignments, while post-Cold War operations in Operation Desert Storm, Operation Enduring Freedom, and Operation Iraqi Freedom reshaped doctrine and force structure. Contemporary reforms respond to emergent domains highlighted by events like the Russo-Ukrainian War and agreements such as the NATO Strategic Concept.
