Cobra troopers can be an unruly bunch at times. They aren't motivated by patriotism, unit loyalty, honor or sense of duty. It takes a brutal, unfeeling taskmaster to whip them into fighting trim and BIG BOA fits the bill to a tee. He has a voice like a bullhorn, fists the size of frozen turkeys and the disposition of a bear with a sore head. Big Boa's training system starts with kicking open the Cobra barracks door at 0500 and making everyone do a low crawl up a mountain while pushing a bowling ball with their nose. Then, it's a twenty mile run through the bramble thickets, more push-ups than you want to know about, and a two mile swim upstream with flak jacket and helmet. After breakfast he starts on the HARD stuff!
