just an idea but as a few peeps have said they want to see accurate acting like soldiers i could come to the filming and give some pointers as i'm in the U.K. military
and as for those guys saying soldiers do not fool around, trust me they do, you have to have a sense of humour in the military. Yeh you switch on when stuffs kicking off but jokes and funny comments are non-stop, if it gets too much the NCOs will crack down on it
and xtreme tactics 101, i know peeps who have laughed when they'v seen a man virtually liquidised by an IED because he was happy that it wasnt him, its grim but thats how some peeps deal wid it, through humour
anyway just an idea if you wanted some military technical/tactical knowledge
