Master-At-Arms

Master-At-Arms First Class (MA1, E-6) is the LPO seat in the Navy's law enforcement and physical-security rating — and the MA rating is small enough that the Chiefs Mess nationally hears about every MA1 who is being watched. You are likely LPO of a security division at a Naval Station / NAS / Naval Submarine Base / Naval Weapons Station security department, the supervisor of the investigations bench (MA-2008), the kennel master or senior K-9 trainer at a military working dog facility (MA-2046), the senior antiterrorism / force protection cell supervisor (MA-2002 / MA-2070), the senior FAST platoon NCO, the senior brig NCO, or the senior ship-attached MAA on a mid-size or large hull. You run 10-25 MAs, and the difference between this and the MA2 seat is not just the rocker — it is legal ownership of the section's readiness, the eEVAL signatures that will determine who pinches chief next cycle, and the JAG / NCIS interface at a level the security officer and department head actually rely on. The Chief Petty Officer selection board is where your next rank lives, and the board is not a test — it is a paper record review. The board reads the last 3-5 EVALs and the Senior Rater's comments; the NEC stack (MA-2002 ATO, MA-2006 crime prevention, MA-2008 investigations, MA-2046 K-9, MA-2070 force protection / ATWO — verify current codes via NAVPERS 18068 Vol II and the current NEC source-rate NAVADMIN); the deployment record and the warfare device; the PME completion (Petty Officer 1st Class Course or applicable Foundational Course for Senior Enlisted Leaders; applicable Navy COOL-funded credentials); and the awards. The LCPO and the CMC review your package 12-18 months before submission. The MA1 who walks into the chief board window with a package assembled in the final 90 days is the MA1 who watches the next slate from the bench. The division training and readiness program is yours to defend, not just execute. Division-level weapons qualification (M9 / M18 sidearm, M4 / M16 service rifle, and any crew-served or specialty weapons your command runs), less-lethal currency (OC spray, ASP baton, Taser where your command fields it), use-of-force and search-and-seizure refresher training, MWD certification status (if your division runs K-9 teams), FPCON drill cadence, and antiterrorism plan currency — the security officer and the department head brief the command on these numbers, and your name is behind the numbers. When the CCRI-equivalent physical security inspection, the no-notice antiterrorism inspection, or the IG-LE-side look comes in, the first file they ask for is the one with your signature. The JAG / NCIS interface at MA1 is qualitatively different from the MA2 level. You are managing case-packet quality across the division's investigation load — evidence custody chain, search authorization compliance, witness statement production, and the referral upward to the NCIS resident agent when the case crosses felony / federal jurisdiction. The trial counsel knows your division. The NCIS special agent in residence has your number. When a case goes sideways, the conversation starts with you, not with the MA2 who ran it. The mentoring mandate at MA1 is load-bearing for your Chief packet and for the Navy LE community's institutional bench. You should be putting at least one MA through a commissioning pathway (Seaman-to-Admiral / STA-21 where accessible, LDO 649X or Chief Warrant Officer LE-side accession track — verify current accession paths against the most recent NAVADMIN each cycle), a Warrant / LDO packet, an NCIS Special Agent (1811-series) application, or a FAST / Naval Security Force pipeline per year. The careers you build at this rank are the ones the MA Chiefs Mess talks about when your name comes up at the next advancement cycle. The post-service federal LE market sharpens at MA1. Your profile is LE-equivalent in training and experience — the agency that will want you has already done its informal vetting through the community. DHS / CBP, USSS, USMS, FBI (1811-series SA pipeline), BOP federal corrections, DoD Police, and the long tail of federal LE positions under USAJOBS / OPM federal hiring authorities are all live conversations at this rank. State and local POST programs in most jurisdictions give meaningful credit for Navy MA training. The MA1 who treats the post-service market conversation as something that starts at the 18-year mark is the MA1 whose counterpart — who started the conversation at 10-12 years — is already a GS-9 at CBP when they both walk out the gate.
