Hah. Funny you bring up rules about guns today. I just had to requal with the M-9 (beretta 9mm nato) using the USAF's "new and improved" qualification course that will of course be replaced no kidding on Monday with an even better new and improved qualification course.
It's 45 practice, and 45 qual rounds, shot at 7, 15, and 25 meters. At 7 and 15 meters, they require two to the body, one to the head. At 25 meters, you shoot some over a horizontal barrier and some against a vertical barrier. One of the toughest is at 25 meters, you have 25 seconds to shoot 3 rounds over a horizontal barrier, drop to a knee and reload, and shoot 3 more still kneeling and using a vertical barrier to brace yourself. It's similiar to what you'd have to do if you were firing over the hood or trunk of a car, dropped behind to reload, and continued firing from a low position around the side of the car.
For those who are familiar, my score was 45-28-9, good enough for expert. 45 total on the paper, 28 in the chest circle, and 9 in the headshot circle. The min for expert is (if I recall correctly) 42-25-6 and the min for qual only is 35 out of 45 just hitting the paper. The course is a heck of a lot tougher and more realistic than it used to be, which is a good thing I think. The last time I qualified, it was the "old" course with only center of mass shots and 36 total rounds, and I put 35 out of 36 into the center circle. That was pretty easy for me because I've been shooting almost all my life, but the new course was actually pretty challenging, and probably a better course now that even USAF support personnel are tasked with patrols and convoy duty.
