I'll thru my two cents in here. I was in Iraq in 91, 03,04,05 & 06' with my old unit the 5th SFGA. While it is forbidden to bring your personnal weapons into theather there is some leeway depending how far out you are. Even at the flag pole this grumpy old E8 carried numberous foreign weapons (MP5s, FAL, MG3) besides my issued M4A1, M14 NM, M79, Mk 13, M107, M1911A1, M9 etc. During my years there I have aqcuired the following revolvers in Iraq. Smith M29, Colt Diamondbacks 2", Smith M10 2", Korth .357 with gold trim, Webleys MK IV, V & VIs, Enfield No 2s, Rossi 38 2". Have had ammo for all the guns at various times. (several thousand rds of .455). However never carried those, just used them as range toys.
The Iraqi people have a rich and deep firearms culture. They may now own one rifle and 60rds of ammo per house hold. Very few pistols are allowed and they have to have a permit for that. The most used rifle is the selectfire AK followed by the SKS and then Enfield rifles.
As far as "Green Berets" that is our issued headgear, never worn in country. Green Berets is an excepted name for us, even though our correct title is US Army Special Forces.
Here's me and my son at his first Regimental Formation known as "Donning of the Green Beret"
To answer your orginal question if a team member found a Smith 940 in 9mm it would be a nice inside the pocket carry to back up his other 3-6 guns.
