To piggy-back, in a way, on what
@RobLyman wrote my last military job was running a Pre-Mobilization Training Assistance Element. Basically I spent several months of weekends and ATs at Camp Craphole getting ARNG units ready to deploy so they wouldn’t have to spend three or four solid months at Fort Shithole getting ready to deploy. My last unit was a UH-60 battalion. They were good people, eager to do a good job, but instead of flying I was teaching them how to react to contact on the ground, IED avoidance, base defense, and other things that are good to know, but not as necessary as NVG flying, brow-out landings, and other scary aviation stuff. Sure, they got lots of work up flight hours, but the battalion commander was frustrated that many of his new guys wouldn’t be ready because they were busy spending time with training that while good to have was not as necessary as training you must have.
