Couldn't do that any more. They took the guns out of the BUFFs. Stupid Clymers in the old Log Command. The radar the controlled those guns (along with the gunner of course) was getting unsupportable. Even back in the mid '70s when I was in AF log command (as an LT, engineer, not a loggie) they had in for that radar and those guns. However, I was told that about the time they had the powers that be convinced to remove them, some Sgt. shot down a MiG over North Vietnam, and it was a couple of decades before they could finally pull off the removal of the "stinger".
