There was a detachment of Gurkhas attached to 5th fleet security Baharain, seconded from the Royal Navy liason. Wonderfull people, deadly as hell, and to a man, they HATE that old story!!!
(And yes, they have to draw blood when they pull out that knife. I used to tell my people to please not ask to see the things, as they would nick their own thumbs before sheathing it. One curious guy did, however, offer his own thumb to be nicked.)
