Is there any way I can renegotiate my contract to change my MOS?

It's not a high action/glamorous MOS that for sure, but it is an important one in that you'll be integral in keeping your units vehicles and motor pool operational. You'll get shit for being a POS and not a mechanic, don't let it get to you. W/o you mechanics can't do their jobs, and there are civilian jobs that will equate to this but mostly at car dealerships and parts stores. Its a start And I'd you stay in and reenlist you can always reclass.

Hi John, I was a 92F while I was in. There are pros and cons to any position that you work while in service. If unable to change your MOS, which is likely, I would advise to do your job the best you can and if given the opportunity to reenlist, try to reclass to a different MOS. Regardless of the job that you do in the Army, my advice is to take advantage of tuition assistance early in your career. College credits and or a degree is going to give you a big advantage when it comes time for promotions. Good luck!

What MOS?
