Headquarters and Service Battalion (H&S Bn), typically found within divisions and major commands of the United States Marine Corps, plays a crucial role in providing command, administrative, and logistical support. Originating in the early 20th century as part of the Marine Corps’ evolution into a modern fighting force, H&S Battalions have enabled the effective coordination of complex operations. Over the decades, they have supported major conflicts, including World War II, Korea, Vietnam, and recent operations in Iraq and Afghanistan, ensuring frontline units receive essential services and supplies. Today, H&S Bn continues to be the backbone of Marine Corps readiness, adapting to new technologies and mission demands.
