Supply Transportation MOS 64B20

• Vietnam War Era MOS: The 64B20 MOS (Light Vehicle Driver) was a U.S. Army Military Occupational Specialty used primarily during the Vietnam War era, responsible for operating and maintaining wheeled vehicles for troop and supply transport. • Critical Logistics Role: 64B20 soldiers played a vital role in ensuring the constant flow of ammunition, food, fuel, and medical supplies to front-line units, often under dangerous conditions. • Convoy Ambushes: Supply transportation units, including 64B20 drivers, were frequent targets of ambushes along supply routes in Vietnam, such as the infamous "Ambush Alley" on QL19. • Multi-Skilled Duties: Besides driving, 64B20 soldiers were trained in basic vehicle maintenance, convoy defense tactics, and emergency field repairs. • Nickname “Red Ball Express”: The tradition of naming supply convoys dates to WWII's "Red Ball Express"; in Vietnam, some 64B20 units informally adopted similar nicknames for their vital missions. • Women in Transportation: The 64B20 MOS was one of the first Army specialties opened to women in the 1970s, reflecting changing military personnel policies. • Famous Vehicles: 64B20 drivers operated a range of vehicles, such as the M35 “deuce-and-a-half” truck, which became an iconic symbol of Army logistics. • Medal Recipients: Several 64B20 soldiers received commendations and medals for bravery, including Silver Stars and Bronze Stars, for heroic actions during supply missions under fire. • MOS Evolution: The 64B series MOSs were merged and reclassified in the 1990s into the 88M (Motor Transport Operator), reflecting Army efforts to modernize and streamline logistics roles. • Unsung Heroes: Despite being less celebrated than combat arms, 64B20 transportation soldiers were often called the “lifeline” of Army operations, as units would “run on beans and bullets” delivered by their hands.
