The Air Corps refers to a branch of military service focused on aerial warfare and operations. It is responsible for the use of aircraft in combat, reconnaissance, and support missions. The term is often associated with the United States Army Air Corps, which was established in the early 20th century and played a significant role during World War II. In many countries, the Air Corps has evolved into a separate air force, such as the United States Air Force. This branch operates various types of aircraft, including fighters, bombers, and transport planes, to ensure national security and support ground forces during conflicts.
