Am in the 305th in Tucson.
After OTS, you'll have to move to a UPT base for the T-6 portion of Phase I/II. After 6 months of that, then you'd go to Rucker for the last six months of Phase III of UPT in the UH-1. You'd then have to do land and water survival school, as well as H-60 school at Kirtland. All told, about 24 months of training.
The Comm/Inst will be a basic help, but not much beyond that.
