United States Marine Corps Forces Special Operations Command (MARSOC)

MARSOC is an umbrella organization that covers several United States Marine Corps special operations elements (excluding those remaining Force Recon elements dedicated to USMC ops). MARSOC itself is under the umbrella of SOCOM (Special Operations Command).

MARSOC consists of:

Marine Special Operations Regiment (MSOR)
- Headquarters Company
- Marine Special Operations Battalions (MSOBs)
  - 1st MSOB
  - 2nd MSOB
  - 3rd MSOB
  The MSOBs are MARSOC's combat units. MSOB operators are trained in direct action, special reconnaissance, foreign internal defense (training foreign military forces) and unconventional warfare. Each MSOB contains 4 Marine Special Operations Companies (MSOCs). Each MSOC contains 4 Marine Special Operations Teams (MSOTs) of 14 Marines. The 1st and 2nd MSOBs were initially formed from the corresponding existing 1st and 2nd Force Reconnaissance companies of the Marine Corps. The 3rd MSOB was eventually formed from the Marines Special Operations Advisor Group, a previous MARSOC unit, which specialized in foreign internal defence and unconventional warfare operations.
