There are two ways a military prisoner gets out: serve to their minimum release date or get parole. Either way, the person is going to be placed into a strict form of post-release conditions. For those who get to their MRD they will go into the Mandatory Supervised Release Program.
MSR (Mandatory Supervised Release) is very similar to parole. Individuals released on MSR must adhere to the conditions of release and are under the direct supervision of a parole/probation officer. Individuals released via MSR remain under supervision and must abide by all conditions of release for the full length of their sentence unless a portion of the sentence has been remitted by the Board. After successful completion of MSR, individuals are released from supervision and have fully served their sentence. An individual who violates the conditions of MSR is subject to sanctions for misbehavior that range from warnings to revocation of MSR and return to military confinement.
The individual on parole and MSR is under the direct supervision of a United States Probation Officer (USPO) until the full sentence has been served or the Army Clemency and Parole Board remits the remaining portion of his sentence. The difference between the two is an individual is eligible for parole after serving one-third or more of his/her sentence, while an individual released on MSR is released when he has served until his minimum release date and has submitted an acceptable release plan. Failure to provide an acceptable release plan could require the individual to serve his full sentence in confinement.
