As someone who just finished BCT and is currently at AIT(different MOS), just tell him to be prepared for the most immature people he's ever met. Fort Jackson was basically the hood, and the trainees there had no sense of self-discipline or self-respect. I'm almost done with my AIT, only 3 more weeks, but I do wish I had gone Air Force or Navy. The level of intelligence and the standards are better in both those branches. The Army in my experience just pushed anyone and everyone through, even those who were undeserving, to retain a good attrition rate. With that being said, BCT is extremely easy, the drill sergeants weren't that bad, and the food wasn't terrible. I lost 20 lbs just based on how much we were outside and how humid it is. The PT is easy also. I do wish the DS were still allowed to hit trainees and that PT and smoke sessions lasted longer than 5-10 minutes. He'll make it through both with ease, as long as he doesn't draw negative attention to himself. Also, AIT is 10x worse than BCT in terms of lack of discipline. The DS at AIT don't give two rats what you do, it's a little frustrating, but I'm done in 3 weeks.
It's too late for you, but in order to not freak out the OP:
There is an exponential relationship between the distance from the maneuver company and the lack of discipline in a group of Soldiers. Infantrymen, scouts, and tankers are enthusiastically policed by their NCOs. Soldiers in the maneuver battalion FSC are close, but not quite. Supporters in the brigade support battalions are less disciplined. Supporters in division support brigades are even more undisciplined. Keep going.
By the time you get to the theater-level units, the impetus on personal discipline has virtually vanished.
The same phenomenon exists in TRADOC units as well. Drill sergeants at Benning, etc. are a lot more excitable than drill sergeants at Jackson. Fort Lee has a reputation of being one of the most... relaxed... posts in the Army.
You've never been in the Air Force or Navy, but I assure you that they are not failing any more people out of basic than the Army is.
*This is not an insult to any individual person. Of course there are strong officers and NCOs in sustainment brigades just like there are weak officers and NCOs in maneuver units.
