Just wanted to clairfy:
The pockets on the arms of our AR CADPAT uniforms are, indeed, Mods. When we arrived in Kandahar, we were told to submit 2 combat shirts for alterations. They were taken to shop on the board walk where the velcro pockets from inside the lower large pockets were removed and sewn onto the sleeves. This was done becasue it is hard to get into your pockets when you have a body armour on (an idea stolen borrowed from the Americans)... and since we (guys out side the wire) wear our body armour all the time (except first thing in the morning, when sleeping in Panjwaii... just before an A10 hits you... damn it) It only made sense to have pockets on the sleeves.
Personally, I found them fairly useless... cool looking, but hard to get into, as they were hastily made, with way too much velcro on the flaps... and too high up.. its pretty hard to reach across your body with armour on.
Anyway... it would be nice if they put that on all of our combats, but I doubt that will happen.
