Not to mention that a good 8 hour course will give you more training with a pistol than most military get.There are numerous training courses you can take. You don't need to have military/combat experience.
I am sure someone will correct me if I'm wrong, but i don't believe most of them get *any* pistol training unless they happen to get an MOS that authorizes them to carry one.
A rifle in combat is a very different thing than a pistol in a self defense situation.
