Has anyone noticed how terribly impolite some can be on this site?

I attended all the USAF survival schools in preparation for my participation in the South East Asia War Games. At the longest school at Fairchild AFB (about 2 weeks) an individual who had the opportunity to find himself on the ground in a hostile environment stood in front of the class holding the USAF survival vest above his head. He asked what we thought the most important piece of survival equipment might be. Almost every piece of gear in the vest was shouted out, the gun, the radio, the medical kit, the knife... He dropped the vest and pointed to his head and said, "your brain, your knowledge, your training, your ability to remain calm and think." Bearing that in mind, some of you are dead already.
