C- copy all.
There is hope. It may all depend on the circumstances for the USMA denial. USMA may have been "full" for your condition -- they may have already used up their waivers for condition "X" on other candidates (i.e. MOC slate winners, recruited athletes, etc.). I have seen it reported here that there are some conditions where USMA has a limit on the number of particular medical condition waivers.
The good news for you is AROTC has already determined that they want you (vs the situation with USMA where you were in the "competitive pool") thus if AROTC can do a waiver, they most likely will... Best wishes to you ... And thanks for being willing to serve.
