The 23d Tactical Fighter Wing accepted its first A-10 Thunderbolt II in December 1980. Nicknamed The Warthog by its pilots, the A-10 was designed to provide close air support for ground forces. One of the most advanced features of the A-10 was its deadly tank-killing 30mm Gau-8 cannon. Built to survive, the A-10's ability to take and deliver punishment was indeed a threat to those who would unsheathe the sword of aggression.
