Communications Chief

E-6 (Staff Sergeant) · Marines

E1–E3E-4E-5E-6E-7E8–E9
HEADS UP

SSgt 0699 is where the Communications Chief designator earns its weight. You are no longer a specialist who leads — you are a communications integrator who happens to have come up through one of the four source MOS. The GySgt board is the next gate, and the platoon you build here is the evidence the board reads.

The Honest MOS Read
Staff Sergeant with the 0699 designator is the real entry point to the communications chief identity. Whether you entered the 06xx field as a 0612 wireman running field wire in the rain at Camp Lejeune, a 0627 SATCOM operator aligning terminals in the desert at Twentynine Palms, a 0631 network admin building VLANs in the comm shop, or a 0671 data systems admin managing servers at the regimental S6 — at SSgt you are expected to be past the boundaries of that primary MOS. You run the communications platoon. Fifteen to thirty Marines across sections covering wire, tactical radio, SATCOM, network, and data systems. You are the SNCO who answers when any of those capabilities fails. The lateral designation to 0699 per MCO 1300.8 recognizes this formally. The practical reality is that the designation follows the demonstrated capability, not the other way around. The regimental S6 and the communications officer have been watching since the Sgt tier whether your communications plans covered capabilities beyond your own specialty. The SSgt who writes an integrated PACE plan that accounts for wire degradation, SATCOM rain-fade, network routing failures, and server application crashes — all simultaneously — is the SSgt the communications officer trusts with the MEU command element's communications during the deployment. That trust is what the 0699 designator represents. You build the communications support plan for battalion-level and MEU exercises and deployments. You write three to four FitReps per cycle on your section chiefs and senior Cpls under MCO 1610.7. You brief the regimental communications officer on platoon readiness across all capabilities at the combined-arms rehearsal. You manage the COMSEC account for the platoon's full controlled-item inventory — keying material, crypto devices across radio, network, and SATCOM families — under MCO P2000.11. You mentor two to three Sgts toward Career Course graduation and GySgt-board readiness with cross-capability depth, not just depth in their primary 06xx specialty. The GySgt selection board under MCO 1400.32 is the next career gate. The board reads the full record: FitReps with relative-value placement, PME completion (Career Course required, SNCO Academy Advanced Course preferred), composite score, awards, education, deployment record. The SSgt who is building a FitRep profile that says 'this SNCO can run a battalion communications section across all 06xx lanes and mentor the next generation of section chiefs' is the SSgt who is competitive for GySgt selection. The daily work at SSgt shifts from section execution to platoon integration and institutional communications planning. You are troubleshooting multi-layer outages that your section chiefs cannot resolve alone — the SATCOM failure that is actually a network routing issue, the network outage that is actually a COMSEC key expiration, the server crash that takes down the VoIP across the entire CP. You are running the TMDE calibration cycle for the platoon's full equipment inventory. You are briefing the regimental S6 on communications readiness in a format that the MEF G6 can brief without translation. And you are developing the next cohort of section chiefs who can do all of this without you in the room — because the test of the communications chief is what happens to the platoon's communications when the chief is at the combined-arms rehearsal and not in the comm center.
Career Arc
  • 01SSgt pin-on via centralized SNCO selection board under MCO 1400.32.
  • 020699 Communications Chief designation applied per MCO 1300.8 — formal recognition of cross-capability breadth.
  • 03Communications platoon sergeant assumption — 15 to 30 Marines across all 06xx capability sections.
  • 04Career Course completion (resident or CDET); SNCO Academy Advanced Course slated on the GySgt timeline.
  • 05MEU deployment or ITX rotation as the platoon sergeant — the operational evaluation that the GySgt board reads.
  • 06FitRep writing for three to four section chiefs and senior Cpls per cycle.
  • 07GySgt centralized SNCO selection board — paper-record review.
  • 08SgtMaj-community visibility begins: the regimental S6 knows your name.
Common Screwups
  • ×Carrying a capability-lane bias from your primary 06xx MOS into the communications chief billet. The wireman SSgt who undervalues the network, or the network SSgt who dismisses the SATCOM section, produces a communications plan with a predictable failure point the communications officer has to fix.
  • ×Missing Career Course or SNCO Academy Advanced Course PME. The GySgt board reads PME completion explicitly; missed gates narrow the path and there is no recovery within a board cycle.
  • ×NJP, DUI, fraternization, or inappropriate relationship at the SSgt level — terminal for GySgt board competitiveness and any 1stSgt/MSgt track visibility.
  • ×FitRep inflation. Writing FitReps on section chiefs that the reporting senior cannot defend at the battalion FitRep review. The SSgt who inflates burns the reporting senior's relative-value credibility and the communications officer remembers it.
  • ×Delegating the integrated COMSEC account to individual section chiefs without a platoon-level reconciliation. The IG audits the account at the platoon level. Section-level tribal knowledge does not survive the audit.

A Day in the Life

  • 0500Wake. Phone check — overnight platoon issues, equipment alerts, Marine-in-crisis notifications. Text the duty NCO for overnight status.
  • 0530PT formation. Take platoon accountability. Report to the communications officer or 1stSgt.
  • 0545-0700Unit PT. You run with the platoon. The section chiefs set the pace for their sections; you set the standard for the platoon. Wednesdays may be platoon humps with communications equipment.
  • 0700-0900Hygiene, chow, change into cammies. Walk the comm shop and the equipment spaces. Meet with the communications officer and the 1stSgt for the morning sync — 15 minutes on the day's priorities, the regimental S6's tasking, and any platoon issues.
  • 0900Morning formation. Brief the platoon. Section chiefs brief their sections on specific tasking.
  • 0915-1130Work call. Platoon training — integrated communications node setup exercise, cross-section troubleshooting drill, COMSEC key load and rotation exercise. Or: you are at the battalion BUB with the communications officer, briefing platoon readiness to the S3 and the regimental S6. Or: you are at the regimental S6's planning session for the next exercise.
  • 1130-1300Chow. You eat with the other SNCOs and the communications officer. Conversation is platoon and company level: equipment status, training gaps, COMSEC posture, FitRep timeline.
  • 1300-1500Afternoon work. FitRep drafting for section chiefs. COMSEC account inventory and reconciliation. Equipment deadline report. Counseling sessions with Sgts — quarterly mentorship on Career Course, composite score, cross-capability development. Career Course or SNCO Academy Advanced Course study.
  • 1500-1630Final formation. Sensitive items check across all sections. Platoon-level COMSEC accountability. Next-day brief.
  • 1630-1800Stay 30-60 minutes with the communications officer for the daily AAR — what went right, what needs attention, what the S6 needs for tomorrow.
  • 1800-2200Personal time. Married SSgts: family. SNCO Academy study. The post-20-year retirement math starts becoming relevant. After-hours coordination with section chiefs or Marines in crisis as needed.
  • Field / MEU / ITXThe clock collapses. You are the platoon's senior communications enlisted during the exercise or deployment. The communications officer is in the planning cell; you are in the comm center. Every capability is your responsibility. Sleep when the communications officer rotates you out.

Weekly Cadence

The Mon-Fri rhythm at the 0699 SSgt level runs on the company and battalion training calendar and the communications officer's planning cycle. Monday is planning — the communications officer and you synchronize the week's training, the equipment maintenance schedule, the COMSEC inventory timeline, and any regimental S6 tasking that landed over the weekend. You brief your section chiefs by 0930. Tuesday through Thursday is execution. Platoon-level training — integrated communications node exercises, cross-section troubleshooting drills, collective task rehearsals against NAVMC 3500.44. You observe the section chiefs running their sections; you intervene when the integration layer fails — the gap between two capability lanes that only the platoon sergeant can see. Thursday may be equipment maintenance day or the motor pool cycle. Friday is the BUB cycle, equipment status reconciliation, and the communications officer's release brief. The regimental S6 may pull you for a planning session on the next exercise or deployment. The second rhythm is the battalion and regimental work: the SNCO huddle with the company gunny (weekly), the regimental S6 comms chief council (monthly if the regiment runs one), the MEU PTP timeline (compressed during the workup). The SSgt who is on the GySgt track is at the regimental S6's office regularly. Field rotations and MEU deployments collapse the weekly cadence. The platoon operates around the clock. The COMSEC accountability is continuous. The equipment status changes hourly. The communications officer is briefing the battalion commander on the platoon's readiness daily — and the quality of that brief depends entirely on the quality of the status the SSgt delivered that morning.

Key Skills — How to Drill Each

  1. 01
    Build an integrated communications support plan for a battalion-level or MEU exercise — wire, tactical radio, SATCOM, LAN/WAN network, data systems, VoIP, COMSEC key plan — that the regimental S6 can brief without rewrites.
    Start with the operational timeline, not the equipment inventory. What does the commander need to communicate, to whom, by when? Build the PACE plan backward from the mission requirement. Assign capabilities to each PACE layer based on terrain, distance, available equipment, and degradation risk — not based on your comfort zone. The COMSEC key plan must cover every device family in the plan with load, rotation, and destruction timelines. The equipment timeline must account for setup sequence dependencies (the network switch must be up before the VoIP, the SATCOM must be aligned before the WAN link). Brief the regimental S6 in the format the G6 uses at the MEF BUB. The communications officer who receives a plan he can brief without editing is the communications officer who writes a clean FitRep.
  2. 02
    Write three to four FitReps per cycle under MCO 1610.7 that the reporting senior can defend at the battalion FitRep review.
    Keep running notes in the platoon sergeant's day-book during the rated period. Draft Section A attribute rationale tied to specific events: section MCCRE rating, MEU PTP milestone, COMSEC inspection result, equipment readiness rate, Marine development outcomes. Rehearse with the reporting senior before the report transmits. The SSgt whose FitReps survive battalion FitRep board scrutiny is the SSgt whose reporting senior assigns harder section chiefs to.
  3. 03
    Manage the COMSEC account for the platoon's full controlled-item inventory across all crypto families.
    The COMSEC account at the platoon level spans every crypto device family in the 06xx inventory — TACLANE for network encryption, fill devices for radio and SATCOM crypto, keying material across multiple key types. Daily inventory, two-person handling for every transaction, destruction records current, IG-ready documentation at all times. Run a monthly platoon-level reconciliation that cross-checks every section's local inventory against the platoon account. The SSgt who passes every COMSEC inspection clean through a full deployment cycle is the SSgt whose integrity is never questioned.
  4. 04
    Troubleshoot a command-post communications outage that involves multiple capability layers and restore the primary capability within the operational window.
    Multi-layer outages are the test of the communications chief. The CP goes dark: is it the network switch, the SATCOM link, the server application, the power supply, or the COMSEC key expiration? The 0699 SSgt diagnoses by walking the layers systematically — physical layer (cable, connector, power), data link (switch port, VLAN), network (IP routing, DNS), transport (firewall ACL, NAT), application (server service, VoIP registration), and crypto (key status, COMSEC device operational). Restore in the priority the operations order demands — voice first, data second, or whatever the commander needs to maintain C2. Brief the communications officer on fault, restoration timeline, and risk before the S3 calls to ask.
  5. 05
    Mentor two to three Sgts into Career Course graduates and SSgt-board-ready candidates with cross-capability depth.
    Each Sgt section chief gets quarterly mentorship sessions with development objectives tied to the SSgt competitive package: Career Course completion, FitRep relative-value profile build, MCMAP Black Belt progression, cross-capability training assignments. The honest assessment: which Sgts are building the cross-capability breadth the 0699 track requires, and which are deep specialists who will serve best in their primary MOS at SSgt? Both are legitimate outcomes. The communications chief who develops two Sgts to SSgt-promotable with cross-capability depth is the communications chief the regimental SgtMaj names.
  6. 06
    Run the platoon equipment inspection and TMDE calibration cycle for the full communications inventory.
    The platoon inventory spans wire gear, radio equipment, SATCOM terminals, network switches and routers, server hardware, test equipment, and the TMDE calibration schedule. Run the equipment inspection against the CMR (Consolidated Memorandum Receipt) and the TMDE schedule quarterly. Deliver the deadline report to the communications officer before the window closes. Deadlined equipment with a parts-on-order report is an honest answer. Deadlined equipment with no report is the platoon sergeant's failure.

Manuals & References — What Chapters Matter

  • NAVMC 3500.44 — Communications T&R Manual (platoon-level collective standards)
    The T&R manual contains the collective standards the regimental S6 evaluates your platoon against. Build the platoon training plan against the collective tasks. Brief the communications officer on T&R completion rates and the gap analysis before every major exercise.
  • MCWP 6-10 — Marine Corps Communications
    You operate at the battalion and regimental communications plan level now. The integrated MAGTF communications architecture your platoon supports is described in this document. The communications officer's planning is graded against it; your execution is graded against the plan.
  • MCO P2000.11 — Marine Corps COMSEC Policy
    You own the account for the full platoon and the answer when the IG asks. The handling procedures, accountability standards, destruction requirements, and inspection criteria — all of it is your responsibility across every crypto family in the platoon inventory.
  • MCO 1610.7 — Performance Evaluation System
    You write FitReps on section chiefs and senior Cpls now. The FitRep policy, Section A mechanics, attribute marks rubric, and relative-value math — re-read before every reporting cycle.
  • MCO 1400.32 — Marine Corps Promotion Manual
    The GySgt selection board mechanics. The SSgt-to-GySgt board is paper-record selection-board based. Your FitRep relative-value profile across the most recent reporting cycles is the primary input. Understand the board's mechanics well enough to build a competitive profile.
  • DISA STIGs and RMF (Risk Management Framework) documentation
    Network and server segments in your platoon have STIG compliance and RMF accreditation requirements. The ISSM validates compliance; the MCEN accreditation framework governs the network boundary your platoon operates. You own the platoon's compliance posture.

Standards — How to Hit Each

  • Career Course completed; SNCO Academy Advanced Course slated as the GySgt board approaches.
    Career Course is the PME the GySgt board expects. The SNCO Academy Advanced Course at the regional SNCO academies is the next tier. Pull the Advanced Course slot the moment the GySgt board timeline clarifies. Resident slots compress when the year-group moves into the zone.
  • Black Belt MCMAP — the platoon expects the senior SNCO to lead by example.
    At SSgt, Black Belt is the bar. Black Belt Instructor (BBI) is the visible differentiator. The platoon's MCMAP belt progression rate under your leadership is visible to the company gunny and the regimental SgtMaj.
  • Platoon COMSEC account at zero discrepancies through every IG and unit inspection.
    The COMSEC account spans every section in the platoon. Monthly platoon-level reconciliation. Two-person handling for every transaction. Destruction records current. IG-ready at all times. One discrepancy at the platoon level is the platoon sergeant's discrepancy.
  • FitRep relative value above battalion average — one weak cycle on the GySgt board moves the timeline by years.
    The relative value on your FitRep is the board's primary read. The SSgt who is rated in the top block by the reporting senior, with attribute rationale tied to specific operational outcomes, is the SSgt who is competitive. One weak cycle — one FitRep where the reporting senior cannot defend the marks — can delay GySgt selection by an entire board cycle.
  • All platoon communications capabilities operational or formally deadlined with parts-on-order before exercise start.
    The regimental S6's BUB slide depends on your equipment status. Deliver the deadline report with parts-on-order status and estimated restoration date. No surprises at the exercise start line.

Technical Mistakes — Concrete Consequences

  • Delegating the integrated communications plan to a single section chief because 'that is their lane.'
    The communications plan that was written by the wire section chief covers wire beautifully and leaves SATCOM as a one-liner. The SATCOM failure during the exercise reveals the plan's seam. The communications officer rewrites the plan himself. The platoon sergeant's FitRep reads differently than it would have.
  • Writing FitReps as wish lists instead of evaluations.
    The reporting senior who defends an inflated section chief at the battalion FitRep board remembers the SSgt who wrote the input. The SSgt whose section chiefs are not getting GySgt at the rates the FitRep input implied loses relative-value credibility. The communications officer adjusts the next reporting cycle accordingly.
  • Allowing section chiefs to manage their COMSEC accounts in isolation without platoon-level reconciliation.
    The IG audits the platoon account, not the section accounts. A discrepancy that existed at the section level because the platoon sergeant never reconciled is a platoon-level discrepancy. The report goes to the communications officer with the platoon sergeant's name on it.
  • Treating the NIPR/SIPR network boundary as the network section chief's problem.
    A NIPR/SIPR spillage incident in the platoon's communications node is the platoon sergeant's incident. The investigation does not care that the spillage was in the network section's equipment. The spillage report goes to the ISSM, the communications officer, the regimental S6, and the IG — and it has the platoon sergeant's name on it.
  • Hiding a platoon capability gap from the communications officer to avoid the conversation.
    The communications officer finds out at the exercise start line from the S3 when the capability fails to come up on schedule. The conversation the SSgt was trying to avoid becomes the conversation the SSgt has with the company gunny and the regimental SgtMaj — which is a different conversation entirely.

Career Decisions at This Rank

  • GySgt board preparation — building the FitRep profile the board reads.
    The GySgt selection board under MCO 1400.32 is paper-record based. The FitRep relative-value profile across the most recent cycles is the primary input. Build the profile intentionally: seek the hardest platoon-level assignments (MEU communications platoon, ITX lead platoon), deliver clean COMSEC inspections, develop section chiefs who get promoted, and write FitRep input that the reporting senior can defend at the battalion FitRep board. One weak FitRep cycle moves the GySgt timeline by an entire board.
  • 1stSgt vs MSgt fork — which track to build toward.
    The 1stSgt vs MSgt fork at E-8 begins shaping at SSgt. 1stSgt (the 8999 designator) is troop leadership: company senior enlisted, daily formation, discipline, climate, family readiness. MSgt is the staff track: operations chief at regiment or MEF, the G6 senior enlisted. Both are real careers with real authority. The honest self-assessment: are you a troop leader or a staff planner? The SNCOs who know you will have an opinion. Ask the regimental SgtMaj. The answer shapes every assignment choice from SSgt forward.
  • B-billet timing if not yet complete.
    If you reached SSgt without a completed B-billet (DI, MSG, recruiter, instructor), the SSgt window is the comfortable opportunity. Most successful communications chiefs completed at least one B-billet at the SSgt or Sgt level. Declining all B-billets is visible on the board read. The MSgt staff track may absorb the absence better than the 1stSgt troop track.
  • Retirement timeline at 12-16 years TIS — the continuation pay window and the 20-year decision.
    Under BRS, continuation pay at the 12-year mark is a financial decision point. The 20-year retirement math (2.0% per year of service, TSP match) compounds. Senior 06xx SSgts with clearance and clean records are valuable in the civilian market — defense contractors, federal civilian IT (DISA, NETCOM), cleared commercial IT. The calculus of staying for E-8 vs ETSing as a senior SSgt is the most important financial decision of mid-career. Run the math with a financial counselor before the continuation pay decision.

How the Seat Varies by Unit Type

  • Infantry battalion communications platoon sergeant (1st/2d/3d MarDiv)
    The default 0699 SSgt assignment. You run the communications platoon for a rifle battalion. The platoon covers the full 06xx spectrum in a small footprint — forced integration across capability lanes. The MEU rotation cycle defines the OPTEMPO. The communications officer is typically a junior captain; you are the experienced SNCO who makes the communications plan work.
  • Communications battalion platoon sergeant
    Larger platoon with more specialization. You may have deeper capability-specific sections with more equipment. The training environment is more structured. The 0699 value: you integrate across larger sections with more Marines, but the forced cross-capability integration of the infantry battalion is less intense.
  • MEU communications platoon sergeant (afloat)
    The strongest FitRep-building assignment at SSgt. You are the senior communications enlisted on the MEU, supporting the MEU command element and the BLT. The PACE plan is tested under real contingency conditions. The communications officer writes your FitRep based on MEU-SOC certification results and contingency response performance. A clean MEU deployment as the communications platoon sergeant is the strongest evidence the GySgt board can read.
  • III MEF / Pacific rotation
    Forward-deployed communications platoon sergeant under III MEF. Interoperability with allied forces adds complexity to the PACE plan. The operational tempo is different from CONUS. The III MEF SgtMaj community has its own slate dynamics.
  • Regimental or division S6 staff SNCO
    Staff billet rather than troop leadership. You are the S6's senior enlisted, managing the S6 shop's communications planning and coordination. The assignment builds the MSgt staff track profile. Less direct troop leadership but more visibility into the institutional communications architecture at regiment and division level.

What Good Looks Like at This Rank

The good SSgt 0699 is the platoon sergeant the communications officer can walk out of the pre-deployment planning session and trust that every node — wire, SATCOM, network, server, VoIP — will be up on the operational timeline, the COMSEC account will pass the IG, and the section chiefs can brief their capability assignments without the platoon sergeant standing behind them. His section chiefs are getting GySgt-board-ready with cross-capability depth. His Marines re-enlist because the technical credibility and the leadership of the platoon are both real. The communications officer has mentioned him to the regimental S6 as the next communications chief candidate before the GySgt board convenes. The test of the 0699 SSgt is what happens when the CP goes dark during the MEU deployment. The SSgt who can walk into the comm center, diagnose the multi-layer outage — network, SATCOM, COMSEC, application — and direct the restoration in the priority that restores command-and-control fastest is the SSgt the communications officer trusts with the hardest deployment. That trust is what the 0699 designator means at the SSgt level: not a specialist who leads, but a communications integrator who happens to have come up through one of the four source MOS.

Preview — The Next Rank

GySgt 0699 is the communications chief billet — the senior 06xx enlisted in the formation. You run the communications section at the battalion or regimental level, or serve as the senior enlisted in the regimental S6 shop: 25 to 60 Marines across the full capability spectrum. The communications officer writes the plan; you make it real. The promotion math at GySgt to MSgt/1stSgt (E-8) runs through the centralized SNCO selection board. The 1stSgt vs MSgt fork is explicit at the E-8 board: 1stSgt is troop leadership (communications company senior enlisted), MSgt is the staff track (operations chief at regiment, MEF G6, HQMC C4). Both pin at E-8; the slate determines which billet you walk into. The daily load at GySgt shifts from platoon management to institutional communications leadership. You build and defend the battalion or regimental communications architecture. You write FitReps on SSgts that determine who becomes the next GySgt. You brief the regimental SgtMaj and the MEF G6 on communications readiness. The test is no longer whether you can troubleshoot a multi-layer outage — it is whether you have built a platoon of SNCOs who can troubleshoot it without you in the room.
