H AND M

• Origins of H & M Units: In military parlance, "H & M" often refers to "Headquarters and Maintenance" companies or units, which provide vital command, administrative, and logistical support to combat units. • US Marine Corps H&M Squadrons: In the USMC, "H&M" designated Helicopter Marine squadrons, combining both attack and utility helicopters before the roles were separated into HMLA (Light Attack) and HMH (Heavy Helicopter) squadrons. • Vietnam War Role: H&M squadrons played a crucial role in the Vietnam War, providing medevac, troop transport, resupply, and close air support, often under intense enemy fire. • First H&M Squadron: H&M-362, the "Ugly Angels," was among the first USMC H&M squadrons, activated in 1952, and became famous for their daring rescue missions in Vietnam. • Unit Insignia: H&M units often had unique insignias or mascots, such as the Ugly Angel for H&M-362, fostering unit pride and camaraderie. • Transition to HMLA: In the 1980s, the USMC reorganized H&M squadrons into HMLA (Helicopter Marine Light Attack) units, reflecting advances in helicopter technology and mission specialization. • Legacy Aircraft: H&M squadrons operated iconic helicopters like the UH-1 "Huey" and the AH-1 "Cobra," which remain symbols of American air mobility. • International Equivalents: Many countries have similar "Headquarters and Maintenance" or "Helicopter and Maintenance" units, though designations vary (e.g., UK’s REME workshops). • Support Functions: H&M units are responsible for a wide range of support functions, from vehicle and equipment repair to intelligence and communications support for frontline units. • Heroic Actions: Members of H&M units have received numerous commendations for bravery, often risking their lives to evacuate wounded or deliver supplies under fire.
