Nanuck, you just lost more creds. I remember how small my m-14 felt in a morter attack on our base in Vietnam. Another thing came to mind. One day a convoy was being stalked by a tiger (that's a great big cat with black and yellow stripes) . The guy on top of the of the apc opened up with a 50 callber machine gun. This really poed (made him mad) the tiger. Ole tige attacked the APC and was finished by multiple rifle and pistol rpunds. So you're right too small of a defensive weapon can just make an assailant mad. This is probabbly why the Bradley fighting vehicle has a 20 mm.
