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.

, this led to the first fighter aircraft whose purpose was to shoot down enemy reconnaissance and artillery spotting aircraft, and to protect one's own aircraft from being shot down. At this point the purpose of aircraft was still to act as an adjunct to traditional armies and fleets operating in the traditional way. However, as aircraft became more technologically sophisticated military theorists of the interwar period began to think of

missions.
In order to acquire a close air support capability armies sought to expand, establish or re-establish their own tactical aviation branches, which are usually composed of helicopters, rather than fixed-wing aircraft.
With the development of unmanned aerial vehicles some armies have begun to use small unmanned combat aerial vehicle, battlefield UAVs, not attached to army aviation units, but rather directly attached to artillery battalions as spotters, and with the smallest and lightest drones being deployed by individual infantry platoons to provide real time local reconnaissance.
Tasks

The tasks of each army's aviation units are defined slightly different, depending on country. Some general characteristics include:
*Tactical offensive action (anti-tank warfare, air assault, and
