I remember seeing the Virgin Soldiers on telly many moons ago but can't remember much of it. I'll look for Dog Soldiers next time I'm in the video store, curiously enough this thread has just reminded of an excellent film I saw back when I was a kid about an Australian SAS unit in the Vietnam war, I think it was called the odd angry shot, I'm off to google it.
Edit: Just found it on IMDB http://www.imdb.com/title/tt0079652/
