The **9th Infantry Division Direct Maintenance Medical Company (DMMC), nicknamed "DAO,"** was a specialized support unit within the U.S. Army’s 9th Infantry Division. The DMMC was responsible for providing direct maintenance and medical support to the division’s maneuver brigades, ensuring that vehicles, equipment, and medical needs were met close to the front lines. Activated during the Vietnam War era, the unit played a critical role in sustaining the division’s operational readiness during combat and training missions. The "DAO" designation reflected its unique dual mission, and its legacy endures in the history of combat service support within the U.S. Army.
