I am considering (strongly) CBRN (Army) as my MOS when I enlist next month. Who can give me first hand experiences on AIT, assignments, etc?

I would look at a different MOS. Almost all of the 74D's that have worked for me and with me get stuck in the S3 shop doing everything but 74D work. The ones that get placed in a company or troop work in the orderly room, again not doing 74D work.

Kelsey Chlovechok if you are with a chemical unit you will receive great training and do your job. If you are stuck in another (any other type of unit) you will be the residential expert and be the one fitting everyone for a mask, doing inventory for the chemical equipment, and allegedly for officers you get stuck doing the USR (a report nobody likes to do). While most Commanders want everyone to do their job and train in their job it is especially hard when there are only 1 or 2 people of that MOS in the unit.

The question is do you feel so strongly that you want to learn CBRN that you are willing to risk not doing that job later on?

NOTE: All MOSs have some issues and all will eventually lead to staff time if you stay in long enough regardless if you stay enlisted or go officer.

Are you sure you want to be exposed to live chemical warfare agents? Your graduation requirement is handling nerve agent in AIT. So if that sounds appealing to you then get after it.

The first thought that comes to mind is to tell you is make sure that the MOS you pick will transition into a civilian job/career. Are you planning on making the military a career? When I was in I absolutely loved my MOS! If you pay attention and study the information giving to you, you will be fine. I thought the classes were easy. I graduated in the top 20%. Make sure you keep all of your notes and handout/study sheets even after you graduate. I remember referring back to those papers in order to help keep things fresh in my head. It was so awesome to have the knowledge I had because I had others that out ranked me coming to me and asking me questions because they didn't know the answer. I ended up being second best in the battalion. If I had stayed in longer I know for a fact that I could have been the best. I remember going through the live nerve agent part of AIT and I thought it was awesome. Yes, I was nervous at first but it helped me build confidence in my gear. It also helps teach you how use your equipment properly. I miss being in the Army. Just pay attention and don't get sidetracked with the ones that don't pay attention. You are there for yourself and to improve your life skills and knowledge. Always hold your head high. Not all females and males have the guts to be in the military. Also you will be doing other tasks that will not be related to your specific MOS, but keep in mind that you will be at the bottom in rank and that crap happens. I did end up doing my MOS for the company I was in but I also had other tasks thrown at me to do on top of my doing my MOS. I am glad that you took the time to reach out and ask questions and able to get straight answers. You also need to keep in mind that not everyone that has the MOS feels the same about it. You will hear terrible things and you will hear good. That is with any MOS you end up picking. Good luck.

If you are going active, run away from cbrn. If you are guard or reserve, it's pretty good for you.

Being a CBRN in a non CBRN unit can be very discouraging depends on the unit you go. I was assigned to the ADA unit and deployed with them. It was easy and no excitement. My job was mostly being a CBRN NCOIC working with Air force counter part as well as being in charge of my unit orderly room. If you are lucky or wait for the next enlistment, you will be able to anywhere you want pretty much since 74d is in the almost every unit's MTOE. You also get your promotion pretty quick. I got my e5 in 2 years. And currently working on e6 part . 74d promotion points drop like other combat MOS. You can do this! Chemical dragons!

There are very few mos that provide as many civilian (FEMA) certifications as a chemical specialist. Try to stay assigned to chemical units and you will have a full and rewarding career.

AIT will be at Fort Leonard. There are many skills, SQI, and ASI you can get. You can earn HAZMAT certifications when you attend certain CBRN Schools like MASCAL, dismount recon and the NCOES schools

I was CBRNE and I loved it

I spent 20+ years as 74D, and just retired 2016. The best part? You can be assigned to any type of unit. I was in (in order) Blackhawk helicopter, Mechanized Infantry, Chemical, Armored Cavalry, Artillery (both rocket and cannon), Finance, Basic Training, and Special Forces. You have to ask yourself what you think you'd like to do as your everyday job. As a 74D, I was chemical, then I was admin, then I was both, and of course as you gain rank you get the opportunity to train others and really have fun with it.
If you're sent to Fort Leonard Wood, you're going to attend OSUT -One Station Unit Training. That means your 8 weeks of Basic Training and your 13 weeks of A.I.T. are with the same Drill Sergeants and same Battle Buddies and same barracks etc for all 21 weeks. It's not a bad thing, unless you can't get along with someone. Remember, Basic is about breaking down your civilian "I" mindset, and turning you into a member of a TEAM that will react to an order no matter what it is" "Drop and do push-ups!" or "Assault that bunker!" If you do what you're told- with enthusiasm, you'll excel in anything. Later on, YOU can be the one barking those orders!
BOTTOM LINE: No matter what MOS you choose, don't let those descriptions you read at the recruiter's office (or MEPS) influence you. Those are mostly descriptions of what your senior years are like. As a lower enlisted, you're stuck doing stuff you didn't sign up for. But trust me- the journey is worth it. I'm more than able to talk to you via phone if you want.
