I have to agree with Waldorf's post. I enjoyed the military talk and the attempt to create military missions. I hope this gives the audience some idea of how harsh the conditions are, especially since the gun fire is usually aimed at them. The "gun fire" was squibs or some other tiny explosives going off on the set. As for blacks not being able to swim, I thought it was ironic the the two non-swimmers were black. We have blacks on our Olympic swim team. Of course other countries do also. I think the stereotype actually comes from blacks living in the cities with little or no opportunity to swim. Anybody who has ever watched that famous surf movie that was made in the 60's or 70's where the surfers are going around the world to seek the perfect wave saw the part about South Africa and the people who lived on the beach. They were natural swimmers and swam their entire lives. And they were black Africans.
