Yep, living on base in the hotel rooms , pretty nice. He and his college roommate (NG) are sharing a 2 bedroom suite. Food is sooooo much better than at Ft Knox.I taught FA BOLC (Fire Support) and later CCC at Sill. It is a great course and the instructor certification is incredibly rigorous so the folks on platform tend to be very well versed as well as experienced in what they are teaching. The exact number varies by iteration but the ratio tended to be about 20-30 days of field time out of the 18 week course though it gets more stacked towards the end with the week long capstone exercise in week 17. Is he living on post. I know that was the plan when I left the installation which is how it was when I went through the course. I found that to be very helpful as you always had a cohort n the same building/hall who were studying the same problems so study groups were very easy to coordinate. Tell him to take advantage of the time there to get in/stay in the best shape possible and seek any follow on schools that they offer.
He shouldn't need a pass to travel home unless he's wanting to take a Friday or Monday in conjunction with the weekend. The necessity for a mileage pass is dictated by the local commander, however, it's usually 250 miles.
