Army Instructor Course

I agree with all others. Going through a formal instructors course for crewmembers, many of the same elements were there. These kind of courses are very beneficial in the way you get to interact with an audience beyond just murdering them with power point. Having the identifier also carries a little weight when you come across an opportunity to sway branch in a certain direction for duty assignments, and of course holding a broader variety of positions around a unit. Not a waste of time at all.

I haven't been, but I've had it recommended to me multiple times from both superiors and subordinates. If you're interested and think it will open doors for you, go for it!

Being Navy, and having a slightly different set of rules when it comes to instructing, the basis of being an instructor is the same: YOU are THE Subject Matter Expert. Even if you end up teaching some obscure course (or something completely outside your MOS specialty), it'll give you more knowledge in certain areas. Where I work (Gulfport, MS), Seabees assigned to instructor jobs can do everything from MOS-specific courses, to something completely outside of their assigned rate (MOS). Take myself as an example. My rate is Utilitiesman (big ol' word for 'Plumber'), but I've taught everything from basic combat skills and land nav, to convoy operations and MOUT, to crew-served weapons and Primary Marksmanship Instruction. Overall, it benefits troops that I've trained, and myself. Not to mention, the teaching Naval Enlisted Classification (NEC) of Instructor, 9502, gets put on my SMART transcript and is worth 6 total credit hours, 3 upper and 3 lower.

If it's the same for my Army Brothers and Sisters, it could put you that much closer to a degree and would reflect on your fitreps/evals. Just one word of advice if you do decide to do it: know your stuff, and don't try to bluff your way through. Troops can smell BS a mile away, and you WILL lose credibility as an instructor.
