Check out this awesome video of an A-10 Warthog getting in some range time with its 30mm GAU-8 Avenger Gatling Gun. I guarantee it will be worth your time.
The A-10 Warthog was designed to incorporate a massive 30mm Gatling Gun intended to decimate Soviet tank formations in Europe. Though it never was used for that purpose, the A-10 Warthog has been used with a great deal of success supporting troops on the ground in Iraq and Afghanistan.
The distinctive Brrrrrrrtt sound of the A-10 Warthog on a gun run is like no other sound in the world. Watch the video to see what I mean.
Was that cool or what? I don't know about you, but I wouldn't want to be on the receiving end of an attack from an angry A-10 Warthog.
