A Soldier in the middle of a gunfight in what appears to be Afghanistan experiences a failure to fire with his AT-4. He probably never lived this rocket failure down.

What you're looking at in this video is the world's most excited Soldier. He gets to run out into a hot position and take a shot at the Taliban with his AT-4 shoulder-fired rocket. There is never a more exciting time in the life of an Infantryman.

For the second half of the video however, you're looking at the world's most disappointed Soldier. He ran out there in the middle of a gunfight and took his shot, unfortunately the rocket didn't want to come out and play. He then had to make the walk-of-shame back to his boys with an unfired rocket.

It's okay dude, everyone has performance issues once in a while.
