S.C. Code § 25-1-2860
Before the vacation of the suspension of a special court-martial sentence which, as approved, includes a bad-conduct discharge, or of any general court-martial sentence, the officer having special court-martial jurisdiction over the probationer shall hold a hearing on the alleged violation of probation. The probationer must be represented at the hearing by counsel if he so desires.
The record of the hearing and the recommendation of the officer having special court-martial jurisdiction must be sent for action to the person exercising general court-martial jurisdiction over the probationer. If he vacates the suspension, any unexecuted part of the sentence must be executed, subject to applicable restrictions in Section 25-1-2855.
The suspension of any other sentence may be vacated by any authority competent to convene, for the command in which the accused is serving or assigned, a court of the kind that imposed the sentence.
