The creation, implementation, and consolidation of the Army Aviation Branch dominated the 1980s. Prominent aviators, as well as other Army leaders, had debated the establishment of Aviation as a separate branch since the time of the Korean War. The opposition to a separate aviation branch had resulted in part from Army attitudes regarding the Army Air Corps and the U.S. Air Force. In Army circles, both of these aviation organizations were believed to have been unreliable in performing their mission of supporting the ground forces—even after having been given resources to do so. Since Army Aviation had demonstrated its commitment to the support of the ground battle in Vietnam, however, opposition to a separate aviation branch began to wane. Also, Army Aviation had grown in size and technological sophistication. This growth caused increasingly complex problems in training, procurement, doctrine development, proponent responsibility, and personnel management. Many non-aviators as well as aviators became convinced that these problems could be solved more effectively by the creation of an aviation branch.
