The Marine Corps has developed an operational Reserve Component that relies on transitioning Active Component Marines. However, the Marine Corps' efforts to encourage Active Marines to join the Reserves upon leaving active duty are ad hoc and individualized. To strengthen the operational Reserve, the Marine Corps must take a more systematic, institution-level approach to attract transitioning Marines. This could include educating Marines about Reserve opportunities, assisting with the transition to civilian life, and mentoring Marines who join the Reserves. An improved transition process would benefit both the individual Marines and the Marine Corps by maintaining experienced talent in the Reserves.
