Courses with a Reserve Cut-Off have required pre-course work associated with the class. This is the last date that the USAASC course manager can give you a RESERVATION. This does NOT mean that this is the last day that you can APPLY for the class. Students who apply on the cut-off date will not get a reservation. Students must submit their application through AITAS at https://www.atrrs.army.mil/channels/aitas/main.asp, the supervisor must concur with the students request (through AITAS), and USAASC must approve the request. All three steps must be completed on or before the reservation cut-off date as shown in AITAS.
