Unless they plan to send the MS2's to CIET there would be no other training unless he requested a slot for Airborne, Air Assault, CULP, ect. If they do offer him Airborne, Air Assault ect, he would be able to decline the offer. There were a couple cadets in my son's battalion that declined these schools so they could take internships, they were already planning on going Guard so they didn't need the bump the schools would give them for Active Duty. The internships were with companies they hoped to work for after graduation.
