As a 16 year Army vet who has flown multiple helos. I would not fly guns in general and absolutly not fly the Apache because to begin with there are no peacetime missions for the airfram. Thus you will spend most of your time in simulators and the other tidbit going to/from the firing ranges shooting dummy warheads. And the OR rate is very low, because of it's complexity. The marines have a better idea updating the Cobras instead. this is only a opinion. Have a blast.
