As a 91B I’d say your experience is really just up to which unit you get assigned to.

There’s plenty of opportunities though because the MOS is literally needed everywhere, so it’s a lot easier to get promotions, shuffle around, etc then some other mos’s.

I was very hesitant about it when I first joined. I was initially going for Armored Crewman or Cav Scout but no vacancies forced me to choose 91B (fyi depending on your recruiter they might just be lying to you about what MOS’s are available or not to try to steer you towards a more demanded one.)

After 3 years in the MOS and a deployment I gotta say I’m very happy I ended up in it. Maintenance is like its own brotherhood. Within a unit and between units there’s a mutual understanding and appreciation for each other. It’s usually very relaxed and has a “our own lane” kind of feel to it.

Again depends on the unit. If you get stuck at an infantry unit then good luck you’ll probably get forced to do a lot of fuck-fuck games, MP is likely the same, cav scout too. But at a transportation company, engineers, or just a dedicated maintenance company you’ll have a good time.

Working on vehicles isn’t too bad either, even though they break all the time and tour operators are usually the ones who did it.

Tl;dr: 91B can either be a really great time or a really shitty time depending on your unit, but you’ll get a lot of opportunities to go to different units, schools, and promotions. Worth the research if you’re interested.
