The IRR includes individuals who have fulfilled MSO and chose to remain in IRR. Which option best describes this statement?

• A. They must deploy every year
• B. They are still in active duty
• C. They have fulfilled MSO and chose to remain in IRR
• D. They are civilian contractors

Answer: (C)

The main idea is understanding what the Individual Ready Reserve (IRR) represents. IRR consists of people who have completed their required service obligation and are not currently serving on active duty or in a Selected/Ready Reserve status, but who can be recalled if needed. When someone has fulfilled their MSO (the initial service obligation) and then chooses to remain in IRR, they are continuing to serve in a reserve-capable status without active duty. They aren’t deployed every year, and they aren’t currently on active duty. They are military personnel who, while civilian in daily life, can be called back to active duty if mobilization becomes necessary. Civilian contractors are not part of this military reserve framework.
