I never said they shouldn't be "gaining additional training and maintaining readiness for a time of war." I just think there are more productive ways to do that. Have the engineers do civil projects; have the infantry work as policemen, or firefighters; have the officers work in management of various companies. Basically, keep them integrated into society.

I wouldn't trust my life to a general who hadn't also successfully run a company full of people who didn't care what he thought and quit when he did something stupid. You may be an experienced military X, but you'd probably be a better X if you also knew how to do X as a civilian. In fact, you'd better be ready to do X as a civilian when your service is terminated, however that may happen.
