A network engineer is sent over to Iraq due to his National Guard status being changed. Immediately after he steps off the plane, he's hit with a wave of heat and a drill sergeant pushes a gun into his hands and tells him to report to the firing range. He gets to the firing range, grabs a magazine, puts the magazine in and lays down an impressive spray of bullets. The drill sergeant, suitably impressed grabs his binoculars, looks at the target, but sees no bullet holes. Sensing the engineer's embarrassment, he barks at him that bullets aren't free, the US Government has gone to considerable expense to train him, feed him and supply bullets, but, take another magazine, breathe before firing, and hit that target. The engineer breathes, fires a little more carefully and the drill sergeant seems happy. He grabs the binoculars, looks down at the target and can't believe his eyes. Not a single bullet hit the target. The drill sergeant, notably irritated at this point starts yelling at the network engineer, telling him that his country is depending on him and he better hit the target this time, and hands him another magazine. The network engineer taps the magazine on his helmet, blows some sand off, places it in the rifle, puts his finger over the end of the rifle, pulls the trigger and shoots the tip of his finger off. He tells the sergeant, the bullet is leaving the rifle just fine, the problem must be on the other end.
