Does anyone have info on 11Bs PCSing to Ft. Benning (how is it, typical jobs there, etc.)?

That somewhat depends on what unit you’re PCSing to. Home of the Infantry has a pretty wide set of things you can be doing, everything between Scoolhouse to Line company to Ranger Bat.
Benning has great opportunity for schools at least.

A lot of support for Officers and NCOs going to school. Unless you go to 3ID then it’s the regular Army. There is a fair amount of things to do here. You should like it but it’s different.

I just came back from ft benning and the jobs there varry depending where at on base you are and your unit PCSing
