HHD USASGV

**Headquarters and Headquarters Detachment, United States Army Support Group, Vietnam (HHD USASGV),** was activated in the early years of the Vietnam War to provide command and control, logistical, and administrative support to U.S. Army operations throughout the Republic of Vietnam. The unit played a vital role in coordinating supply lines, maintenance, transportation, and personnel services, ensuring that combat and support units received the resources necessary to sustain operations. HHD USASGV was instrumental during major campaigns, adapting to the rapidly changing tactical environment and supporting the expansion and eventual drawdown of U.S. forces. The unit was inactivated as part of the overall American withdrawal from Vietnam in the early 1970s, leaving a legacy of critical support operations during one of the most challenging periods of U.S. military history.
