Special operations are conducted by small teams in hostile, denied, or politically sensitive areas. Success depends on the skill, maturity, and professionalism of each member of the team. SOCS are Marines who provide combat support expertise in intelligence, fire support, communications, and military police as part of a Marine Special Operations Team.

The MARSOC Combat Support Orientation Course (MCSOC) is designed to identify Marines from combat support MOS who are interested in a tour in special operations. MCSOC will educate these Marines about the unique challenges, opportunities, training and operations that await those assigned to MARSOC to become SOCS.
