HMMWV Maintenance
U.S. Army Specialist Darius Sims, 35th Air Defense Artillery Brigade all-wheel mechanic, poses for a photo at Osan Air Base, Republic of Korea, April 29, 2022. The high mobility multipurpose wheeled vehicle (HMMWV) has become the vehicular backbone of transportation for all U.S. Forces around the world and are able to continue the mission all thanks to all-wheel mechanics like Specialist Sims, who keep the vehicle in working condition.
