What can I expect in AIT for a 12R?

Your freedoms will be dictated by the Cadre, company policy and your ability to earn said freedoms. Right now, you are going there to learn a trade on the Army's dime. Focus on the steak and not the peas.

Also, I found this little video after a 2 second google search:

I went to ait as 12r a few years back and it was pretty good. It was 6 weeks when i went through. It was definitely more laid back than basic. We took a pt test sometime during our first week there and if you passed then on the weekends you could leave the barracks for about 8-10 hours which was pretty good. Fort Leonard Wood doesnt have alot on base but the mall is pretty decent to walk around and grab some food. Theres a dunkin donuts on post which was cool too. We could have cell phones on weekends only. It was a pretty good ait, a good amount of hands on learning too. Good luck

I’ve never heard of that MOS :(
