H AND M

Certainly! However, "H AND M" could refer to various military units depending on the country and context. In the United States Marine Corps, "H and M" often stands for "Headquarters and Maintenance Squadron." For example: Headquarters and Maintenance Squadron (H&MS) was an essential aviation support unit within the United States Marine Corps. Established during World War II, H&MS provided critical maintenance, supply, and administrative support to Marine Aircraft Groups, ensuring their aircraft remained combat-ready. Over the decades, H&MS units participated in major conflicts, including the Korean and Vietnam Wars, adapting to evolving aviation technology and operational demands. In the 1980s and 1990s, many H&MS units were reorganized into Marine Aviation Logistics Squadrons (MALS) as part of a broader restructuring to increase efficiency and support capabilities.
