Critical Skills Operator
Marine Raider — the primary special operations MOS of Marine Forces Special Operations Command (MARSOC). CSOs are multi-dimensional operators capable of working across the full spectrum of special operations. Training pipeline: Assessment & Selection (A&S), then the 10-month Individual Training Course (ITC), then 6-month language school, then 18 months of unit-level training before first deployment.
“You'll be a Marine Raider — the Marine Corps' contribution to US Special Operations Command. MARSOC operators conduct direct action, special reconnaissance, foreign internal defense, and counterterrorism worldwide. You'll speak a foreign language, master advanced combat skills, and operate in small teams in the most austere environments on earth.”
The pipeline is approximately three years from the day you walk into A&S to the day you deploy as a qualified CSO. ITC alone is ten months and the attrition rate is what you'd expect when you take Marines who are already good and ask them to be exceptional — north of 50% don't finish. You need to be an E4 or E5 with at least three years in, a first-class PFT of 225+, intermediate swim qual, and SOF screening scores that your career planner will know about. The language requirement is non-negotiable — six months at DLI or equivalent, and you will maintain that language for the rest of your career. Once you're operational, you will deploy. The autonomy and capability of a Marine Special Operations Team is the closest thing in the conventional military to being left alone to solve hard problems with a small group of people who are genuinely good at their jobs. Every day you spend in the pipeline earns you something that can't be faked.

You are a feeder-MOS Marine with Raider ambitions, not a badged Raider yet.
You are a feeder-MOS Marine with Raider ambitions, not a badged Raider yet. Your daily job is your current MOS. The 0372 work at this tier is preparation: first-class PFT/CFT habits, water confidence, clean conduct, medical/admin readiness, chain-of-command trust, and learning current A&S and Marine Raider Course gates from official MARSOC sources. The trap is acting like a Raider before the community has selected, trained, and awarded you the PMOS. MARSOC does not need cosplay; it needs Marines whose current leaders would send them into a harder room.
- 01Build a screening-ready record in your current MOS before trying to borrow the Raider identity.
- 02Use current official guidance instead of old pipeline folklore.
- 03Keep fitness, water confidence, conduct, medical, and family readiness from becoming the hidden failure point.
- 04Communicate with precision across teams, partner forces, enablers, and staffs.
- 05Respect enablers and support Marines as part of the mission system.

You are the Corporal at the edge of the MARSOC conversation: good enough to screen, not senior enough to act like the team owes you anything.
You are the Corporal at the edge of the MARSOC conversation: good enough to screen, not senior enough to act like the team owes you anything. You are either proving your current MOS record, fighting for selection, or learning how little the title means without team trust. The work is screening prep, course gates, weapons and CQB fundamentals, communications, TCCC, language/culture exposure, partner-force humility, and the admin that keeps a Marine deployable. If you are not awarded 0372 yet, say that plainly. If you are newly awarded, shut up and learn the team standard before trying to decorate it with personality.

You are the working Raider on a team or section. Your name is now attached to other Marines, partner-force work, and the quality of the brief.
You are the working Raider on a team or section. Your name is now attached to other Marines, partner-force work, and the quality of the brief. You execute, rehearse, brief, maintain equipment, train with enablers, work across cultures, and tell the truth in debriefs even when the truth is ugly. The mission set may include direct action, special reconnaissance, foreign internal defense, security force assistance, irregular warfare, and other MARSOC tasks, but the daily proof is less cinematic: PCCs, PCIs, range plans, reports, language reps, partner-force preparation, and the discipline to keep classified details out of casual storytelling.

You are the Staff Sergeant making the plan survivable and the younger Raiders harder to fool.
You are the Staff Sergeant making the plan survivable and the younger Raiders harder to fool. You turn team intent into training, rehearsals, PCC/PCI discipline, range safety, reporting standards, and honest AARs. You may still be close to execution, but more of your value is now in making other people better before the mission exposes them. You coordinate with enablers, understand authorities, check assumptions, and keep the team from treating confidence as evidence.

You are the Gunny who turns Raider craft into company-level readiness.
You are the Gunny who turns Raider craft into company-level readiness. You manage readiness, training plans, risk, standards, enabler integration, and the friction between what the team wants and what the command can responsibly employ. You still need credibility with operators, but the job now punishes vanity. The best GySgt in this lane makes commanders smarter, junior leaders steadier, and bad assumptions easier to spot before they become bad orders.

You are the senior enlisted keeper of the Raider standard. The community gets healthier or lazier around what you reward.
You are the senior enlisted keeper of the Raider standard. The community gets healthier or lazier around what you reward. You advise commanders, shape readiness, protect ethical standards, manage talent, translate team reality into joint/SOF planning, and decide which shortcuts the institution is not allowed to normalize. The job is not pretending every day is a raid package. It is making sure the force can be employed honestly, sustained over time, and handed to the next generation without a box of hidden problems.

Zero reviews for 0372. Not because nobody has opinions — anyone who’s actually done Critical Skills Operator is carrying a full magazine of them — but because nobody’s put theirs on the record.
So here’s the deal: the first approved review of every MOS becomes its Founding Review. Permanently badged, permanently first. Every person who looks up 0372 from now on reads it before anything else — including the recruiter’s version.
We could fill this page with fake reviews tonight. Plenty of sites do. We never will — which means this space stays exactly this empty until someone who lived it goes first.
