This 1971 U.S. Air Force manual page (Change 2, effective 1 October 1971) records radio call procedures used by two-man F-4 Phantom crews, the Aircraft Commander and the Weapon Systems Officer, known informally as the 'GIB' (Guy In Back). The 'PICKLE, PICKLE, PICKLE' call marked the moment of bomb release. The lower table provides delivery parameters for the Mk 84 Laser Guided Bomb, an early precision-guided munition employed in Vietnam, reflecting the U.S. Air Force's growing shift toward laser-guided weaponry during the later years of the war.
