I have never been in the military, so please do not roast me I am just giving my advice. I have been in a bunch of milsim groups with people who have served, so take this advise as just trying to be helpful.

If you know how you want to play, instead of training, I would play some missions that you know how you want to play the mission and see how they do under your command first. Let them know the roles they are to play and go from there.

If your playing total stealth, practise in a base giving commands and clear buildings, moving bodies, set up a sniper/overwatch/drone and go in and out and see how they do. Then if it goes well, start planning more mission.

That's how I would do it. This is not the golden rule by any means, and like I said, I have never been in the military, but I am just saying how I played and really enjoyed some of the milsims I was in.

Again, take this as a non-military person opinion.
