0631 vs 0111
Network Administrator (USMC) vs Administrative Specialist (USMC)
The Marine Corps promised both of these would "make you a leader." The methods range from "forging in fire" to "death by PowerPoint."
0631: The Uncensored Pamphlet. in the field, you're building tactical networks from scratch — setting up a COC's entire data backbone with military networking gear that is not Cisco no matter how much the recruiter implied it was. Get your CCNA on your own time — the military courses don't go deep enough for the civilian market. 0111: The Other Uncensored Pamphlet. nobody respects admin until something they care about requires admin to fix it — then you are briefly the most important person in the building. The work is repetitive, detail-intensive, and chronically thankless, but the hours are genuinely better than most MOSs and you will never hump a mortar baseplate up a mountain. Neither pamphlet will be featured at the recruiting station. Both should be.
After the Uniform
The part the recruiter skips: what each job actually translates to once you're a civilian — and what it pays.

Recruiter vs. Reality
The pitch versus what people who actually did the job report back.
“You'll build and maintain the network backbone that connects every Marine in the fight. Routers, switches, firewalls, tactical data links — you own the infrastructure that makes command and control possible. CCNA-level networking skills are in massive civilian demand, and the cleared network engineers the Marine Corps produces are exactly what defense contractors and enterprise IT shops are hiring. This used to be lumped together with systems administration under 0651 — now you get to specialize in what matters: the network itself.”
You are the plumber of Marine Corps IT — you own the pipes. Switches, routers, firewalls, cable runs, IP schemes, VLANs, and whatever tactical network gear the Corps is fielding this year. When the 0651 split happened, 31s got the network infrastructure and 71s got the servers and systems. In practice, especially in smaller units, you still end up doing some of both because there aren't enough bodies. In garrison, your life is managing network closets, running cable, configuring switches, and troubleshooting why building 4200 can't reach the print server. In the field, you're building tactical networks from scratch — setting up a COC's entire data backbone with military networking gear that is not Cisco no matter how much the recruiter implied it was. Training at MCCESS covers the fundamentals but you'll learn the real stuff on the job. Get your CCNA on your own time — the military courses don't go deep enough for the civilian market. The good news: networking is one of the most transferable military IT skills. Companies need people who can troubleshoot at the packet level under pressure, and that's exactly what deployed Marine network admins do every day.
“Admin Marines keep the entire personnel system running — pay, records, unit diaries, correspondence, everything that makes a Marine Corps unit function as an organization rather than just a group of people with guns. The organizational and records management skills translate directly to office administration, HR, and government service careers, and the hours are significantly more predictable than the infantry.”
You will become intimately familiar with MOL, MCTFS, unit diaries, and the specific formatting requirements of every administrative document the Marine Corps has ever invented. You are the person everyone comes to when their pay is wrong, their leave was rejected, or their award package disappeared into the administrative void. Nobody respects admin until something they care about requires admin to fix it — then you are briefly the most important person in the building. The work is repetitive, detail-intensive, and chronically thankless, but the hours are genuinely better than most MOSs and you will never hump a mortar baseplate up a mountain. The civilian translation is strong for office management, HR assistant, and government administrative positions. If you can navigate the Marine Corps personnel system without losing your mind, corporate HR will feel like a vacation.
