Ray Allen's Machine Gun Training After Chopper Ride In Afghanistan (VIDEO)

Ray Allen's still shootin' ... but he traded out the rock for an M-240B machine gun!!

The NBA legend has been hitting up U.S. military sites around the world as part of a USO tour -- a tour that included hanging out the side of a helicopter flying over Afghanistan!!!

The video is incredible -- you can see Ray rockin' a sweet pair of Jordans as they fly over the Hindu Kush mountains.

Allen noted, "There were two men on both sides of the Helo up front manning the guns and the two in the back were keeping an eye out just in case someone fired a missile at us."

Yeah.

By the way, Allen also teamed up with Hollywood superstars on the tour including Scarlett Johansson and Chris Evans.
