File talk:US Navy 090705-N-5710P-127 Lt. Cole Evans, an explosive ordnance disposal technician, demonstrates proper handling and firing of the M4 service rifle as part of a course on basic combat marksmanship during operation Infinite Re.jpg

The short barrel on the weapon makes it appear to be a Mk18 CQBR. I'm not going to change the caption because it's possible that the weapon is just an M4 with a short barrel installed. I hope that someone who knows for sure will verify this. Dwane E Anderson (talk) 10:24, 15 February 2012 (UTC)
