On such bomb and strafe missions it was the practice, after bombing, to form a strafing circle, each machine in turn attacking in a dive, the pilot firing his two fixed wing guns (0.5-in in late production aircraft like A9-608) and the navigator/bomb aimer his two gimbal-mounted 0.303s, then turning away from the target giving the wireless operator, with his one free 0.303 mounted on a spigot firing from a hatch on either side, and the turret gunner with his two guns, their turn.
