not that this was a very scary prospect , the american military were a bit crap really , no one else in the whole universe had managed to invent friendly fire ; that is accidentally killing people from other countries who are on your side , certainly no one had had the gall to give it a name and pretend it was ok. no the american military werent such a worry , but it only took one nervous young soldier to accidentally tighten his grip for the whole army to start blasting away .
