A little somethin'-somethin' courtesy of yet another Old Air Force Sarge, Bayouwulf. (And yes, Old AF Sarge's are legion. You never know where one of us might pop up. Just sayin'...)
In the video, note the sound of the Warthog's 30mm cannon. Very, um, "attention getting", innit?
The next picture shows various military ammunition side by side. Give's you an idea of just how big the A-10's gun really is.
Enjoy! (And thanks again Bayouwulf!)
