A militia is OK if you want to go camping and shoot a rifle, but if you want to leap out of jets at night, or launch fighters off the deck of an Aircraft carrier, or rappel out of helicopters or fire artillery guns or fly an attack helicopter, or drive a tank, or a million other things, you still have to join the military.
Between the T/Os and landings, I always gave the crew chiefs some stick time. Not actually by the books allowed, but very much appreciated by the crew chiefs, and as far as I was concerned, a good way for them to more fully appreciate and understand the A/C they worked on.
