ABIW, I wouldn't be too hard on the matelots as 6 of the 8 personnel were Marines. This whole incident became something of a microcosm of recent RM history; first they get lost (anyone remember the amphibious landing exercise in Gibraltar when they actually stormed ashore to be met by two bemused Spanish policemen? Only a few miles out chaps) followed by instant surrender (Falklands?).
So we now have a RM produced pamphlet entitled "The waterways of the Persian Gulf and how to enjoy them", to go with the "Coastal map of Gibraltar" (unused) and "RM Tactics aide memoire" (relevant passage being "Reaction to effective enemy fire: lay weapon carefully on the ground, stand up and raise arms above the head).
Now if THAT doesn't create some interesting feedback......
