Are there any areas that the military should teach more of?

MOS training.... that seems to be the one thing no one gets... Tons of SHARP and EO classes though...

Everyone should be taught how to schedule and plan training very early in their career. These are basic building block skills. Learning how to budget is also a key skill. This helps personally and professionally and is often taught later in the career; sometimes after the individual's career is in trouble.

MOS training, refreshers, things that expand MOS skills.
Combatives.
More Rifle, Pistol, and crew served weapons. You never know what weapon you're going to end up behind, anyone can be in a convoy, on a guard duty, or a small FOB, everyone should be able to contribute.
