Marine Corps Systems Command (MCSC) is the Commandant of the Marine Corps’ agent for research, development, acquisition and sustainment of systems and equipment used to accomplish the Marine Corps mission as an offensive amphibious “force in readiness”. The command provides United States Marines with everything they drive, shoot and wear, and work closely with partners in industry and the Department of Defense to acquire the systems and equipment necessary to ensure mission success.

We provide critical competency resources such as engineering (systems engineering), program management, contracting, financial management, and logistics to eight MCSC Product Groups as well as the Program Executive Officer Land Systems (PEO LS), the Program Executive Office Enterprise Information Systems (PEO EIS), the Joint Program Office for Mine Resistant Ambush Protected (MRAP) Vehicles, and others. In our role as an acquisition organization and a competency support organization, MCSC manages or supports over 35 ACAT I, II, III and IV defense acquisition programs and hundreds of Abbreviated Acquisition Programs.

The areas MCSC supports include IT Systems, Command and Control, Unmanned Systems, Combat Vehicles and Engineering, Expeditionary Power, Training Systems, Infantry Weapons and Optics, Communications, Combat Equipment and Support Systems, Armor and Fire Support, Weapons and Sensor Integration, Radar Systems, Intelligence and Networking Systems, Global Combat Support, and others.

Program Executive Officer (PEO) Land Systems (LS) Marine Corps was established in 2007 and is the Corps' only PEO comprised of 23 weapons systems programs, including a number of Acquisition Category (ACAT) I and II programs. PEO LS is a separate command, reporting directly to the Assistant Secretary of the Navy (ASN) for Research Development and Acquisition (RDA). PEO LS' integral relationship with MCSC leverages infrastructure, competencies and technical authority.

PEO LS manages a diverse program management portfolio of approximately $7B, which includes the Marine Corps' largest ground acquisition program, the Amphibious Combat Vehicle (ACV), an Acquisition Category ID (ACAT ID) program and the next generation, amphibious ship-to-shore capability for the Marine Corps. The PEO LS' portfolio also includes Common Aviation Command and Control System (CAC2S), Ground-Air Task Oriented Radar (G/ATOR) and Lightweight 155mm Towed Howitzer (LW 155). Ground mobility programs include the Joint Light Tactical Vehicle (JLTV), Logistics Vehicle System Replacement (LVSR), Medium Tactical Vehicle Replacement (MTVR), and the Mine Resistant Ambush Protected vehicle (MRAP).
