This Order provides policy for the operation and sustainment of the MCSP, and establishes procedures to assign a sponsor to assist transferring Service Members and their families prior to arrival at the new duty station. The MCSP will also be in effect for those Selected Marine Corps Reserve (SMCR) Members, both prior and non-prior service and their families prior to their arrival at the SMCR unit. The MCSP complements the Unit, Personal and Family Readiness Program (UPFRP), established by reference (c), by nature of its proactive outreach and support to incoming unit Service Members and their families.
