and then you are over the camp and then you are over some fields and then you are over a river , and thats when the crew chief gets up and walks to the front of the helo and grabs a big metal can of .50 caliber bullets and hauls it back to where the .50 is stuck on a pintel with its nose out the window drooping , and he opens the lid of the can and hauls out the bullets on their metal chain and slides the first round into the top of the .50 and hauls back on the charging handles and talks into his helmet and points the .50 out away from the ground and squeezes the thumb trigger and the gun rattles for a second and the chain links float up into the air and on to the floor and smoke slides back from the gun through the helo and you can smell the sharp gunpowder smell and hear the gun echo in your head and you think that this guy thinks we might get shot at and then you think that this is the stupidest thing you ever did in your life .
