What about it?
You can buy dang Gatorade and Bicycle playing cards out in boondock little FOBs all over Iraq. It's not like the US military has some tragic shortage of 5.56mm to deal with.
Which would you rather have for ammo: 1) clean, new ammo from some U.S factory, shipped around the world and sitting in tidy stacks in a warehouse 2) a box of loose Albanian surplus sitting in a feed sack in some unemployed Iraqi's closet? As a split-second NY reload, sure, but not as a general practice.
We've had this thread quite a few times, and when we cut out all the speculation and "here's what _I_ would so if I were in Iraq", it usually boils down to the following:
--Some folks who only had M9s picked up AKs, primarily during the initial invasion when we had less gear than we needed
--A small minority of troops are in very independent small units with a CO who lets them get away with carrying confiscated gear. I knew _one_ EOD team where their GySgt let some guys carry a Sterling, a few AKs, and jury-rig a PKC onto a Humvee that had no 240 for the ring-mount. GySgt himself carried a G3K. He was a THR-type gun lunatic.
--Tons, tons of troops have pictures of themselves posing with confiscated gear, or even pretending to be on an op with them. I've posted my way-cool FAMAS pic here, and it's quite likely that someone on some other forum is using it as "evidence" that the FAMAS is a favorite weapon of US Marines.
That's about what we've gotten out of previous threads. The rest of it is just "this one guy said" and other such things. Long, long-running topic...
