The IRR consists of individuals who have trained and have previously served in what?

• A. Active forces or SELRES
• B. Civilian service
• C. Merchant Marine
• D. National Guard

Answer: (A)

The question checks your understanding of who makes up the Individual Ready Reserve. The IRR is a pool of people who have already undergone military training and have previously served either in the active forces or in the Selected Reserve (SELRES). They’re not currently assigned to a unit, but they are available to be recalled to active duty if needed. This is different from civilians (who aren’t military), the Merchant Marine (civil maritime service), or the National Guard (a separate reserve component with its own units). Hence, the IRR draws from those who have previously served in the active forces or the SELRES.
