because they are war hawks. THE GENERAL policy of naming Army aircraft after Indians tribes, chiefs or terms was made official by authority of Army Regulation (AR) 70-28, dated 4 April 1969. The names were authorized for use in public releases and other documents as a ready reference. The Indian names chosen were very popular among Army personnel for many years.
The Commanding General (CG) of the U.S. Army Aviation Missile Command (AMCOM), located at Redstone Arsenal, near Huntsville, Alabama, had the responsibility of initiating action to select a popular name for an Army aircraft. For this purpose, the CG maintained a list of possible names obtained from the Bureau of Indian Affairs. For brevity the names usually consisted of only one word. When a new aircraft reached the production stage, or immediately before it went into production, the CG selected five possible names. The selection decision was based on the sound, the history, and the relationship of the name to the mission of the aircraft. The names chosen had to appeal to the imagination, without sacrificing dignity, and suggest an aggressive spirit and confidence in the capabilities of the aircraft. They also had to suggest mobility, firepower and endurance. The chosen names were sent to the Trade Mark (™) Division of the U.S. Patent Office to determine if there was any legal objection to their use.
Some Army aircraft, such as the Bird Dog and Otter, did not have Indian names. Those that did not were named before the policy change of 1969 was enacted. AR 70-28 specified that these would not be changed.
