Looks like a regular carbine....

Saw it in a book I just finished reading, None Braver by Michael Hirsh.

Its what the Air Force calls their carbine variants.

All Airforce weapons have a GAU designation. IE a 30cal Minigun is a GAU-17

GAU and GUU are just USAF designations for weapons. GAU is for aircraft-mounted weapons and GUU is for miscellaneous (e.g. personal) weapons, though this doesn't mean the USAF pays attention to this. The 7.62mm M134 minigun is the GAU-2A/B and GAU-17. The original GAU-5/A was a XM177 without forward assist, the Model 610 I believe. Then came the GAU-5/A/A which is the XM177E2. Then there's the GAU-5P and GUU-5P and a bunch of other stuff I don't understand. :) But yes, a Colt carbine, usually without forward assist.

GAU/ GUU are similar to the AR15A3 tactical carbine, but are auto. IIRC, the GAU had the thin barrel, while the GUU variants had a heavier. I could be wrong on that. I have a USAF K9 handler friend who just got issued a new one (GUU), but then he got sent to Iraq, so he isn't answering many questions right now.

My wife refers to to the weapon she carries in Iraq as a GUU. For her it is a Colt M4, full auto.
