What are the different ways to get promoted as a 91B? What is the pay like?

Become proficient at your job and promotions will come depending on time in service and time in grade. The best thing about military pay is that food, quarters, and medical are included. Save your money!

The single most important thing you can do now that will set you ahead of your peers a few ranks down the road is start taking college courses. Just take one at a time, you can do five a year easily like that. You need to take them in person, there are lots of great online schools these days. I recommend Coastline Community College. But there are colleges at the Education center that offer evening courses if your work schedule supports that. If it doesn't, don't let that be the reason you don't start.

Promotions after E4 are a competition for limited slots. Everyone is doing the same things to get promoted - good PT scores, weapons scores, military Ed, correspondence courses, etc - but most E4 91Bs have not started college until they realize they need jt for promotion. Four years down the road when you're competing for SGT or SSG your peers will just be starting college and you'll already have your associates

Wow...things have changed. When I joined the Army in 1973, the MOS 91B was a Combat Medic!

91 series has a lot of upward mobility opportunities', Pass your APFT/ACFT, take online courses that are available through distance learning (education points), education and doing the right thing will pay off. I spent 18 years on the enlisted side then transitioned to Warrant Officer. I always made sure I was waiting on the Army when it came time for promotions, vs the Army waiting on me to complete my requirements. You already started out with a leg up but enlisting as an E2. You can view Army pay charts by using Google. I can promise you pay has increased quite a bit since I enlisted in 1997.
Good luck to you!

Everything up to E-4 is automatic, as long as you don’t have any kind of UCMJ pending.
1 year for E3
18 months with a waiver for E4
2 years for E4 automatic
The pay changes aren’t spectacular because your pay is based around your rank and your time on service. I’ve linked a screenshot of the paygrades and their pay with TOS.

For non Army folks...
Army Wheeled Vehicle Mechanics are responsible, as the title suggests, for handling maintenance and repair of all tactical and some armored vehicles, both heavy and light. ... This job is categorized as Army military occupational specialty (MOS) 91B.

DO YOUR JOB. Do it to the best you can.
Go to every school you can. This should show your leadership that you want to learn and be more valuable to your unit and the army. With each School you earn promotion points.
You will need points from Military and civilian education. so if you have any college credits go promotion points.

Automatic E2 upon entering? Congrats. But for what? JROTC? Eagle scout? College creds?

From E1 to E4 just keep your nose clean and do kick ass work. Let your chain of command know you are there for mission accomplishment and do go things.

After that its a points system. Not gonna get into that a this point in your career. Just make sure that in your off time you are taking college classes and staying fit.

Learn your job, always look for extra duty/responsibility. You know, things that set u apart from your peers. H8 is a good start. Google a military pay chart. Save your money and use the tsp.

Being promoted is cool, but take advantage of the times where you have less responsibilities as well.
