Marine Corps aviation, in “its organization, equipment, and training . . . should be primarily oriented toward performance of close air support.” So wrote a special board in its confidential 1947 report to the commandant of the Marine Corps. Although the Marines’ first “official” use of close air support (CAS) had come in 1927 in Nicaragua, 20 years later the bond between the service’s air and ground forces had not yet been cemented fully. That would occur a few years later in the Chosin Reservoir campaign in Korea—arguably the birthplace of the Marine air-ground task force.
