MarSOC is a component of the US Special Operations Command (SOCOM) that is a joint group consisting of the Naval Special Warfare Command (SEAL / SWCC), Army Special Operations Command (Special Forces, 75th Rangers, Special Operations Aviation), Air Force Special Operations Command and the Joint Special Operations Command (JSOC).
What Is the Difference Between Marine RECON and MarSOC?
There are two Special Operations Capable groups of Marine RECON in the USMC: Battalion and Force. For generations, RECON has been the Special Operations Capable units in the Marine Corps. However, shortly after September 11, 2001, the Department of Defense / SOCOM requested of the Marines to create a special operations command to become a component of the Joint Special Operations Command with skilled operators who were highly trained to conduct special operations all over the world.
There is a difference between the two RECON units as well. The difference, mainly, is who works for who. The Battalion RECON answer to the Marine Division Commander (typically a Colonel in the USMC). The Force RECON Marines answer to the Air-Ground Marine Task Force Commander who is typically a Major General. They both do battlefield operations but Force can be tasked with "beyond the battlefield" operations behind enemy lines taking the fight to the enemy. In essence, the Marine RECON units work for the Marine Corps though they may do joint operations with other military branches in larger scale conflicts.
MarSOC works for the Special Operations Command which also has component commands such as the Naval Special Warfare Command, Army Special Operations Command, Air Force Special Operations Command, and the Joint Special Operations Command. All tend to work together or independently as needed and as the warfighting climate demands to conduct a variety of missions that include direct action, foreign internal defense, counter-insurgency, intelligence gathering, special reconnaissance, and more depending on SOCOM deployment orders.
The Official MarSOC Mission
The MARSOC mission is to recruit, train, sustain, and deploy scalable, expeditionary forces worldwide to accomplish special operations missions assigned by U.S. Special Operations Command (USSOCOM). To accomplish that, MARSOC equips and trains Marines to succeed in austere conditions against a wide range of adversaries.
