What should a prior service marine E5 expect going through OSUT at ft benning?

I have never been infantry so I cannot speak to that piece but I can help prepare you for the culture shock between Marines and Army. I have known several that have come from the Marines and we are not as tight and missioned focused as the Marines. Not a drag on my service, Marines are smaller and can focus more on what is important and as a company grows larger, we lose that. I could never cut it as a Marine officer and I accept that as you and every other service member expect me to keep you alive when blown up. I like to thing I am pretty good at what you expect me to be good at.

Hopefully you won’t do the whole thing but it all depends on how the school house feels that day. It sucks I know but that’s a fact!

Besides that, just play smart thru training.

To my understanding they should have you as an MOS-T but I would assume you will be in a OSUT class when they begin black phase of OSUT aka the official start of the AIT portion.
