The Marine Corps’ Force Structure Review brings change to various aspects of the Corps’ Reserve Force, ranging from fine-tuning of occupational specialties to tweaking unit sizes and locations, or even shifting entire command structures. In some cases units will be re-designated as a different type of unit. The widespread adjustments can create opportunities for the Reserve Marines involved or hasten their departure from the Corps. For the Reserve Force, the effects of FSRG may seem even more accentuated due to the location of Reserve units spread across 47 of the United States, close to Marines’ hometowns; having a different type of significant impact on Reserve Marines than the periodic relocation their active duty counterparts experience every few years. In this photo, Marines carry the retired Marine Corps Mobilization Command colors during a deactivation ceremony. As a result of Force Structure changes, the Marine Individual Reserve Support Organization was stood up in its place. - The Marine Corps’ Force Structure Review brings change to various aspects of the Corps’ Reserve Force, ranging from fine-tuning of occupational specialties to tweaking unit sizes and locations, or even shifting entire command structures.
