Maintenance Battalion

Maintenance battalions provide intermediate (3rd and 4th echelon) maintenance support for Marine Corps-supplied (vice Navy, other service, or contractor-supplied) tactical ordnance (i.e., weapons and weapons systems), engineer, motor transport, communication-electronics, and general support (e.g., generators, refrigeration systems, water purification) equipment of the Marine Expeditionary Force (MEF). Maintenance battalions are typically comprised of a headquarters and service company, as well as five maintenance companies (electronic, engineer, general support, ordnance, and motor transport).
