I have searched and can not find a good list of vehicles the army actively has so I want to ask any former 91B's what you mostly worked on. I am so excited about being a 91B. I am a huge gearhead.

I worked on a variety of vehicles that the military no longer has, 1/4 tons Jeeps were fun to work on. M151A3.

Literally anything with wheels. I was a 63W back in the day, heavy wheel mechanic. We worked on HMMWVs in their many varieties, LMTVs in their many varieties, now-a-days I imagine it includes all the new blast vehicles MRAPs all its cousins and even strykers (but I do believe those have a dedicated MOS as well).

awesome, thank you! Yes your right stryker maintainer is its own MOS. I almost chose that but i felt like i wouldnt like being stuck with just one vehicle and and that being a 91B i would gain alot more knowledge on a large variety of vehicles

As he said, literally anything with wheels. Even Strykers. We have 91Bs in our Stryker unit as well as Stryker mechanics.

PVT (Join to see) yes Stryker 91S is only for Strykers, but the Stryker maintenance program needs all the help it can get. The transition from warranty maintenance to field maintenance was rough.

I originally joined the Army to be a mechanic. I absolutely loved it! I am naturally a gear head as well. Mostly you will be just changing parts. Stay hungry and apply for a SOF unit where you can really use your hands and head. Good luck!

As a newly sworn in member of the Army and a 91B wheeled vehicle mechanic, what vehicles did you work on?

My best advice, be prepared to be a MECHANIC, period. If it has a combustible engine, you will touch it and work on it at some point in your career. I’ve worked on generators, heaters, reefer units, backhoes, Toyota Land Cruisers, Tacoma, and hilux (desiel Tacoma), Polaris MRZR, M850 (Polaris ATV), Polaris switchback (snowmobiles), mraps, literally everything that comes your way that has to deal with mechanics you should have a general knowledge of. Good luck to you.

Good choice of MOS, I was infantry and only thing I worked on was my combat boots, they worked well and took me everywhere. But I always admired the guys that work with a AVR, to retrieve the armor.

PVT (Join to see) - I've been doing all my mechanic work on all my cars since I got out of the Army, and I enjoy all the work. I just did my son's car starter, but it was hopeless, so we had to get another starter. I thought it was just the brushes but, the armature was arched by the brush wiring.
I sure enjoyed finding the problem, I always tell the young mechanics, The hardest part is, trouble shooting the problem.

PVT (Join to see) - The only problem I seen with the Army trying to fix something was the lack of the part they needed. In 1972 on the DMZ Korea, we needed shocks for a 5-ton fuel truck, I was the 50cal gunner on the truck, my squad leader and I had to to go 300+ miles to another base. At that base they didn't have any shocks for our 5-ton, so we did the next best thing, we bought it at the black market.
So, it just shows that the hardest part of being a mechanic is, the trouble shooting, What ever it takes.

The starter is from a 2012 Acura TSX 2.4, if changing the starter, you have to take off the Air Manifold, Throttle Body and alot of vacuum tubes to get access to it. The hardest part was, taking off the two bolts that held the starter on, no room for your hand, and no leverage, but I just, "Motherfy" the tool to get to the bolts.

If you want to talk Jeep, then I have one of those too, and a Mustang, and a 4x4 F-150 Crew Cab, and many other car stories that I worked on, in my life time.

Well it is going to depend on your unit assignment. There are 6 total units with the Hetts 2 National Guard and the rest Army. My old unit has the record for safety and most miles driven through Iraq. 14 million miles, going from the load points in Kuwait and all over Iraq. The Hetts are the trucks that can haul the Bradleys and anything else you may possibly need. Uses a gooseneck trailer where all the axles turn. The newer Hetts have a longer cab where the back seat converts to bunks and 4 door instead of the old 2 door set up. CTIS on all the cab tires. Awesome vehicle! The new contact trucks that held all of our tools were pretty awesome as well. It was a humvee that only had the front seats and the back stripped off and in its place is a huge roll cage box that held all of our tools in foam cut out trays across the sides. The back opened up and we had our parts, welding, and torches in there. Awesome set up. You knew where everything was and if something was missing with just a quick look. The Hemmitt wreckers and fuel trucks we had as well as the duces and some pick ups. Being in a tansportation unit gives you the opportunity to work on all kinds of vehicles. We as the maintenance section installed air ride seats in our vehicles! Made for a much smoother ride. We also built radio boxes for each vehicle so we could listen to music while on haul missions.

Depends on your unit. I'm in a PLS Trans Company, so I work on a lot of PLSs, but I also work on HEMMTs, HMMWVs, and LMTVs. I have buddies I went to AIT with, who only work on LMTVs or HMMWVs because of their unit type.

Expect anything most common would probably be the FMTV (family of medium tactical vehicles) the HMMWV and the HEMMIT platform but don't think that is inclusive if worked on generators, pressure washers, excavators, backhoes, bulldozers, lads, shower units, just about anything that runs on fuel they will ask you to fix best advise I can give you is be flexible and learn to use a TM even if you know what your doing as a mechanic beforehand there is still a lot of good information in the books

You work on anything with wheels.

HMMVs, HEMMTS, FMTVs, water buffalos, trailers, hell I even had to service a water cooler before.
