In late 1965, a panel of high-level officers was selected to evaluate several prototype versions of armed and attack helicopters to determine which provided the most significant increase in capability to the UH-1B. The three aircraft ranked highest during the evaluation After Vietnam, and especially into the 1990s, the missile-armed attack helicopter evolved into a primary anti-tank weapon.
