Think I read somewhere that a .50 cal is approximately 10,000 pounds of force compared to 2,000 for a .22 cal. Those .50 cal bullets are catastrophic if they hit a human body.
Had anyone heard about the troubles the Taliban are having recruting suicide bomber instructors?
The last known instructor was heard saying, while holding a detonator in his hand....."Now pay attention. Because I'm going to show you this once"
