"Not only is it downright unacceptable, it's also illegal and stands in stark contrast with everything the British Army represents"....Oh I don't know. I'd say doing illegal things is pretty high on the list of things that the army represents; illegal wars, illegal torture, extra-judicial killings (a.k.a. murder; usually illegal but I guess it depends who's doing it and who to).
The whole video is pythonesque and it's no wonder people have been ripping the piss out of it.
