An army aviation unit is an aviation-related unit of a nation's army, sometimes described as an air corps. These units are generally separate from a nation's dedicated air force, and usually comprise helicopters and light support fixed-wing aircraft. Prior to the establishment of separate national air forces, many armies had military aviation units, which as the importance of aviation increased, were spun off into independent services. As the separation between a nation's army and air force led to a divergence of priorities, many armies sought to re-establish their own aviation branches to best serve their own organic tactical needs.
