Also, discuss the VEPR and Browning Buckmark .22 (the pistol I'd chamber in 9mm and then give to my S.S. officers if I were Fuhrer. Those things are sleek)
Yes, that's a GAU-8 on a Patton tank. It was GE's entry in the division air defense program back in the 70s. Too bad Ford won, imagine if this beast had gone into production.
