Can a Marine Reservist get orders to go on MSG duty?

Yes, a Marine Reservist can be selected for Marine Security Guard (MSG) duty, but it is not common. Typically, MSG duty is primarily filled by active-duty Marines, and Reservists must meet specific eligibility criteria and undergo a selection process. If selected, they may receive orders to serve in this capacity, often requiring them to temporarily transition to active duty status for the duration of their assignment.
