**HQ, 1st CALC, MAAGV Advisors, US Army Support Command Vietnam, MAAGV** was a headquarters element operating under the Military Assistance Advisory Group, Vietnam (MAAGV), and later integrated into the U.S. Army Support Command during the Vietnam War. The unit’s primary mission was to provide command, control, and logistical support to U.S. Army advisors embedded with South Vietnamese forces. As American involvement deepened, the 1st CALC (Combat Area Logistics Command) played a crucial role in coordinating supply, transportation, and maintenance operations across the theater.
