Sgt. Kevin Montenegro, a military police officer previously stationed in Combined Arms Training Center, Camp Fuji, Japan, poses for a portrait before continuing with the Individual Ready Reserve (IRR) Muster process, Manhattan Beach, California, Jan. 21, 2023. The Marines of the IRR previously served on active duty or as drilling reservists, and now stand ready to augment the active forces in times of war or other contingency. These Marines bring tremendous experience and capability to the United States Marine Corps and are an important part of the “total force.” (U.S. Marine Corps photo by Cpl. Jonathan L. Gonzalez)
