The Selection Process
Assessment and Selection (A&S) is a mandatory 2-phase course to screen physical ability, confidence, situational awareness, and acclimatization.
A&S Phase 1 is a grueling, three-week course that tests the physical and mental capability of each candidate. You will be evaluated on:
- Abandon ship drill
- 300-meter swim
- 11-minute tread
- 12-mile ruck
- Physical in-test
A&S Phase 2 is a mentally and physically challenging evaluation that enables MARSOC to identify Marines that have attributes compatible with special operations missions and the MARSOC way of life.
Becoming a Marine Raider
A&S selects proceed to the Individual Training Course (ITC), a nine-month program that turns a Marine in to a CSO.
Earn it Every Day
Throughout your nine months at ITC, you will learn:
- Medical skills
- Communication skills
- Small unit tactics
- Amphibious tactics
- Combat marksmanship
- Close quarters battle demolitions
- Urban combat
- Special reconnaissance training
- Irregular warfare
