Since we got off topic and threadjacked, I started this.

Ok, I talked to a friend of mine who is going to the naval academy next year, and both his parents graduated from the naval academy as well, so I'd like to think he knows a little bit about the military. He said that there is no restrictions on the uses of the .50 cal sniper in battle. It was first created in the vietnam war for the purpose of killing enemy soldiers at distances of up to 2 miles, now with the possibility of even longer ranges. I can't remember the creator's name, but most sniper movies about the vietnam war were based on him. I believe he has the longest recorded kill record for an American, at over 2 miles. This was with something like a 22 power scope too. All I can say is wow, that gun and that guy are bothridiculous.
