The logistics combat element (LCE) consists of those combat service support units whose primary mission is to, (1) provide direct combat logistics (i.e., motor transport and landing support, and limited engineer support, equipment maintenance, and ground supply services) to specified GCE units or certain aviation combat element (ACE) units as provided by combat logistics battalions and separate combat logistics companies, (2) provide general combat service support across the Marine Air Ground Task Force (MAGTF) by specialized service support battalions, including: dental, engineer support, maintenance, medical, supply and transportation support battalions, or (3) provide immediate command and control, and consolidated Navy personnel administration to subordinate LCE battalions and regiments by the Marine Logistics Group (MLG) headquarters and service battalion. Additionally, this battalion provides communications networking and law enforcement support across the LCE. The headquarters and service battalion also provides specialized services, including: military postal service, Marine Corps Exchange (MCX), and other personal services, to units of all four MAGTF elements (i.e., GCE, ACE, LCE, and CE).
