The Army Reserve celebrates its birthday annually on April 23, marking its establishment in 1908 with the creation of the Medical Reserve Corps. Over the years, the Army Reserve has played a pivotal role in major conflicts, including both World Wars, Korea, Vietnam, and the Persian Gulf War. Today, it remains a critical component of national defense, with Reservists serving in every U.S. state and territories, and deploying to over 30 countries. This day honors the dedication and contributions of Army Reservists, who continue to support combat, peacekeeping, and humanitarian missions worldwide1.
