When I was deployed to the Gulf last year I saw quite a few Cobras at Ali Al Salem Air Base and also at Kuwait International Airport, I've got a couple of photos but the quality isn't very good.
I have no idea if these were Army or Marine machines, there were plenty of personnel from both organisations based at both locations - met some very interesting people.
IIRC there were about 20 or so Cobras at Ali Al Salem, but I didn't see any Apaches - they may have been further North. There were a few BlackHawk types around, had a chat with a HEMS pilot who flew a BlackHawk (variant), he was a reservist just like me - although we don't get to fly at the weekends
Obviously a year on those machines could be anywhere......
