Hey Matt,

My squadron was the first Air Force F-4C unit in action over North Vietnam, the 68TFS. We were equipped the centerline gun, however since the centerline of the gun barrel was twelve feet plus below the pipper on the gun sight any slight deviation on a strafing pass resulted in a real shotgun pattern. Our birds didn't have a lead computing box, that feature didn't show up until the F-4D appeared at Fighter Weapons School at Nellis in 1966!
