HEADS UP

Making ICC is the milestone in this rate — more than any other Navy rating, the fouled anchors on an IC's collar mean something specific to the fleet. The goat locker is yours. The department head briefs around you. The entire division reads the maintenance standard off how you carry yourself at quarters. The first year as ICC is the year the mess forms its permanent read on who you are, so walk in like you know that.

The Honest MOS Read
Interior Communications Chief Petty Officer (ICC) is the milestone rank of the IC rate. The advancement rate from IC1 to ICC is historically among the tighter gates in the surface Navy enlisted community — the IC rate is small enough that the Chief board is reading a limited number of IC1 records, and competitive selection means the sailors who made it are the ones whose LPO tenure produced measurable results visible to multiple senior raters. The job changes more between IC1 and ICC than at any other transition in the rate. As LCPO of the IC division on a surface combatant or amphibious ship, you run ten to twenty ICs and you own enlisted execution from the deckplate to the department head sync. You write Chief-quality eEVALs — typically four to eight per cycle — that pick the next IC1 and ICC slate. You sit at department head sync as the senior enlisted interior communications voice. You walk the spaces during a TSTA, INSURV, or ISIC visit and find the broken maintenance practices before the inspector does. That last capability is the one that defines the ICC: the chief who runs a pre-INSURV walk and finds the CAT-II-potential item in the IC switchboard before the surveyor boards is the chief whose division briefs clean. The chief who finds it when the surveyor does is the one who writes a different kind of lesson-learned report. The IC systems the LCPO is responsible for are not glamorous in the way that combat systems are glamorous — the 1MC sounds like background furniture until it goes down during a real flooding event and the XO cannot talk to the repair lockers from the bridge. The IC chief's job is to enforce a maintenance discipline so thorough that the announcing plant and the gyrocompass navigation feed are never variables in a damage-control event. That means the CSMP is clean before the INSURV, the IC room watch qual standards are enforced, the ESWP tag-out log never has an unsigned clearance entry, and the battle-lantern zone inspection is on the PMS calendar plus the LPO's spot-check calendar. The personnel leadership at ICC is the other full-time job running in parallel. Four IC1s are heading into the Chief board window and they all need a LCPO who mentors the record, not just the application packet. Two IC2s are approaching the LDO/CWO eligibility window and they need specific, honest counsel on whether their records are competitive and what the next 12 months need to produce. One ICFN is about to make a decision that will determine whether his Navy career lasts four years or twenty. The ICC who is only running the CSMP is running half the job. The Chief's Mess itself is the fourth institution in the ICC's professional life alongside the division, the department, and the ship. The mess is the senior enlisted leadership platform — the chiefs who contribute to the mess's professional development program, the mentoring of other rates' chief selectees during initiation, and the goat locker's collective accountability for the ship's enlisted climate are doing the work the mess was designed for. Chiefs who treat the mess as a social club have misunderstood the function.
Career Arc
  • 01ICC selectee: CPO Initiation process — enter with humility, leave with anchors that the mess believes you earned.
  • 02LCPO assumption: 10-20 ICs, full CSMP and 3-M program ownership, 4-8 eEVALs per cycle.
  • 03Chief's Mess integration: contributing member of the ship's goat locker — professional development, initiation mentorship, enlisted climate accountability.
  • 04First TSTA/INSURV cycle as LCPO: the visible test — the IC system material condition brief before the inspectors board.
  • 05Senior pipeline output: IC1 Chief board selectees, LDO/CWO accessions, commissioning program participants — tracked and cited at command level.
  • 06Senior Enlisted Academy (SEA) — the professional development milestone for ICC; timing coordinated with LCPO and CMC.
  • 07ICCS consideration: the NWAE path to Senior Chief is distinct from the Chief board path — the record-building starts at ICC pin-on.
Common Screwups
  • ×Treating the Chief's Mess as a social club. The mess is a working leadership institution; chiefs who arrive at the goat locker with a social mentality and leave with one are visible to every IC1 in the division and to the Command Master Chief, who briefs the CO.
  • ×Stopping personal PT discipline because the anchors are pinned. Sailors read the deckplate harder when the fouled anchors go on — and an ICC who fails the semi-annual PRT is a command-level event that the XO and the CMC both brief.
  • ×Letting an IC1 LPO run a division with degraded PMS discipline because he is 'almost a Chief' and you don't want to undercut him. The ISIC inspector doesn't know he's almost a Chief — the CSMP findings have the LCPO's name on the oversight record.
  • ×Going public with disagreement with the department head or the CO at the department sync level. The disagreement belongs in the LCPO's office or the chief's mess; you walk out aligned. The wardroom and the division both read the alignment, or the crack in it.
  • ×Treating the battle-lantern operability program as administratively low-priority because they rarely fail during a real casualty. The one deck zone with dead battle lanterns during a flooding event is not a performance metric — it is a finding with the LCPO's name on the discrepancy report and the CO's name on the endorsement.

A Day in the Life

  • 0530LCPO is in the spaces before the division. Check the overnight OMMS-NG entries and IC room watch log before the IC1 LPO arrives.
  • 0600Chief's Mess: early-morning goat locker session if the mess runs one — professional development discussion, initiation guidance for the chief selectee class, or command climate brief from the CMC.
  • 0630Breakfast and OMMS-NG review. Any overnight casualty entries or watch-log notes that require LCPO awareness before the 0730 muster.
  • 0730Division muster: LCPO runs the accountability check and the week's priority brief. IC1 LPO receives the tasking; LCPO validates that the IC1's plan is coherent before the division disperses.
  • 0800Department head sync: IC system material condition brief. One page, all open CSMP items with status and resolution dates, INSURV/ISIC liabilities, pipeline status.
  • 0900LCPO counseling session with IC1 LPO: weekly touchpoint on Chief board packet, CSMP posture, and any personnel issues in the division that require LCPO-level awareness or action.
  • 1000Division spaces walk: IC room, gyrocompass room, IC switchboard space, and spot-check of two or three battle-lantern zones. LCPO is looking for the thing the IC1 did not notice, not verifying that the IC1 did his job.
  • 1100eEVAL drafts: review IC1-level draft input; counsel the IC1 on specific measurable bullet language before it goes to the senior rater.
  • 1130Noon meal.
  • 1230Personnel pipeline work: LDO packet review with the IC2 candidate, school nomination paperwork for the NEC pipeline, MILPERSMAN review for any open personnel action in the division.
  • 1400Goat locker: Chief's Mess professional development session or CMC-directed fleet focus area discussion.
  • 1500Unscheduled block: casualty response if anything surfaces, INSURV pre-walk segment if in the approach window, or ICCS/ICCM professional development reading.
  • 1600Pre-liberty accountability: LCPO verifies the IC1's accountability report. All ICs accounted for, all open CSMP items documented, overnight watch assigned.
  • 1700Evening meal. CMC or department head conversation if any personnel issue requires same-day alignment.
  • 1900-2100Senior Enlisted Academy reading list, MILPERSMAN review, or NWAE study for ICCS if in the advancement window. The LCPO who reads every night is the one whose counseling sessions have something current in them.

Weekly Cadence

The ICC's week runs on two parallel tracks simultaneously: the maintenance track and the people track. The maintenance track is managed through the IC1 LPO — you set the standard, verify the output, and step in when the CSMP is drifting or the ISIC approach window is tightening. The people track runs directly: four IC1s with open counseling items, two IC2s weighing the LDO decision, one ICFN who needs a come-to-Jesus conversation about NWAE study before the window closes. The rhythm that matters most for an ICC is the chief's mess cadence. The goat locker meets regularly — the frequency and format vary by command — and the ICC who contributes consistently to the mess's professional work is the one who receives the mess's institutional backing when a hard personnel decision requires the LCPO's recommendation and the CMC's endorsement to mean the same thing. When the ship is in the INSURV approach window, the ICC's weekly cadence changes entirely. The maintenance track dominates — the LCPO is in the spaces daily rather than weekly, the IC1 LPO is briefing the CSMP status every morning rather than weekly, and every deferred MRC and every open CSMP item is a personal decision with the LCPO's name on it. The pre-INSURV window is the most visible test of the ICC's entire tenure, and the chiefs who pass it cleanly are the ones who ran the division at INSURV standard every week of the tour, not the ones who cleaned it up in the approach.

Key Skills — How to Drill Each

  1. 01
    Run an LCPO division of ICs — accountability, training, readiness, discipline, financial counseling, family support — with a weekly cadence the wardroom and the XO can predict without calling you.
    The LCPO cadence has a visible structure: Monday work-center muster with a specific tasking brief, mid-week personnel check (who has an open counseling item, who has a family readiness issue, who has a financial problem the command financial specialist needs to see), Thursday eEVAL input review, Friday accountability close. The XO's read of the ship's enlisted climate comes partly from whether the LCPO's division runs to a visible professional standard. If the XO has to call you to find out what is happening in your division, your cadence is too informal.
  2. 02
    Defend the IC system readiness brief — CSMP, deferred PMS liability, INSURV posture, battle-lantern operability by zone, warfare qualification rates, NEC pipeline — at CO-level sync without the department head rewriting your numbers.
    The CO-level readiness brief has a one-page format: material condition by system area, open CSMP items with resolution dates, the two or three INSURV liabilities that represent operational risk, and the pipeline status (NEC, Chief board, LDO/CWO). The test is whether the department head passes your brief verbatim to the CO's sync. If he rewrites it before it goes up, your brief was not ready. Walk through the brief with the DH informally the morning before the sync — not to ask permission, but to validate that the numbers are current and the framing matches his communication style.
  3. 03
    Walk a real-world TSTA, INSURV, or ISIC maintenance inspection as the senior enlisted IC voice — and be the one who finds the CAT-II-potential finding before the inspector does.
    The INSURV pre-walk is one of the most important things an ICC does in the two months before a survey. Walk every IC space, every gyrocompass room, every IC switchboard space, and every battle-lantern zone on the ship with the same mindset the surveyor will use: is this system in the material condition the TM requires? Are the ESWP tag-out logs current? Is there an unsigned clearance entry anywhere? The LCPO who walks the spaces the week before the survey and produces a list of self-identified CAT-II items that are corrected before the surveyor boards is the one whose division briefs clean.
  4. 04
    Mentor four to six IC1s into Chief-board-competitive candidates over the course of a sea tour.
    Chief-board mentorship is not a one-time packet review — it is 18 months of specific monthly guidance: this month, your eEVAL narrative needs to show a CSMP metric; next month, make sure the NEC nomination is in the pipeline; six months from now, the SWS requalification needs to be on the record. The IC1s who made Chief from your division should be able to name the specific counseling session that changed how they ran their division. If they remember the relationship but not a specific conversation, you were a presence rather than a mentor.
  5. 05
    Operate as the senior enlisted IC technical voice during a deployment, WESTPAC, or surge — including the 0200 call to the XO when a damage-control announcing loop is degraded.
    The 0200 brief to the XO has four elements: what is down (specific system and affected zones), what the diagnosis is (TM reference cited), what the operational risk is (which damage-control zones have degraded announcing coverage), and what the recovery timeline is (parts on hand vs. parts on order, labor estimate). The XO does not want to hear 'we are working on it' at 0200 during a voyage repair — he wants to know whether the ship's damage-control announcing capability is functional for the next watch. Brief that question directly.
  6. 06
    Translate NAVSEASYSCOM, Type Commander, and INSURV program requirements into deckplate maintenance decisions the ICs execute without rewording the message.
    NAVSEASYSCOM and TYCOM maintenance messages arrive in program-management language — system designation codes, OPNAV N4 priorities, INSURV finding category definitions. The ICC's job is to read those messages, extract the deckplate action, and hand the IC1 LPO a specific tasking: 'TYCOM maintenance message 26-XXX requires a visual inspection and OMMS-NG entry for IC switchboard corrosion protection on all installed units by end of quarter. Assign the IC2 to run the inspection this week.' The IC who is still trying to parse the original message three days later was not briefed by an LCPO who does this well.

Manuals & References — What Chapters Matter

  • NSTM Chapter 430 — Interior Communications
    At ICC level you are the technical authority the wardroom calls at 0200 on an IC system question. Know the full chapter at a depth that allows you to answer without looking — not every procedure memorized, but every section known well enough to navigate the chapter faster than the IC1 can. The INSURV surveyor cites NSTM Chapter 430 paragraph by paragraph in the finding; you should know which paragraph before he opens the binder.
  • NAVSEA IC system TMs across the full suite your division owns
    The LCPO's TM knowledge spans the full IC suite — not because you need to execute every procedure, but because you need to know which TM answers which question at an INSURV approach brief. The surveyor asks about the calibration tolerance for the installed gyrocompass model; you should know which TM section and what the tolerance is before he reads the question off the survey criteria sheet.
  • OPNAVINST 4790.4 — Ships 3-M Systems Procedures
    You are now the LCPO who defends the program at ISIC and INSURV level, not the petty officer who fills out the MRC. Know the finding category definitions (CAT-I vs. CAT-II), the CSMP maintenance code standards, and the quarterly coordinator report format. When the ISIC coordinator asks why a scheduled quarterly event was deferred, you cite the authorization chain and the documentation — not a verbal 'the DivO approved it.'
  • MIL-STD-461 — EMC Requirements for Equipment and Subsystems
    At ICC level you brief EMC compliance posture on IC system modifications to the NAVSEA technical representative and the combat systems officer. Know what MIL-STD-461 requires at the system level — conducted and radiated emissions limits, the test categories that apply to shipboard IC equipment — so that when the combat systems officer asks 'does the new amplifier installation meet EMC requirements,' you have a specific answer rather than a referral.
  • MILPERSMAN — articles governing enlisted personnel actions at ICC visibility
    The ICC who needs to look up the MILPERSMAN article number during an NJP counseling session with an IC2 has already lost the counseling session's authority. Know the articles governing advancement, retention, NJP, administrative separations, financial hardship programs, and family separation allowance at a working-knowledge depth — the standard that allows you to answer the question in the room before you pull the article to verify the detail.
  • CPO 365 / CPO Initiation guidance and Senior Enlisted Academy reading list
    The Chief's Mess holds the ICC to the professional development standard the goat locker and the wardroom expect. CPO 365 and the SEA reading list are the formal framework; the informal standard is whether you are contributing to the mess's professional development program and whether the IC1s you mentor can articulate specific guidance you gave them, not just that you were 'supportive.' Read the list. Use it.

Standards — How to Hit Each

  • CPO Academy/Chief's Mess transition complete; standing as a Chief in the mess and on the deckplate — not a Chief in title only.
    The mess reads the new ICC in the first 90 days. The chiefs who contribute to the professional development program, participate fully in the initiation process for the next selectee class, and bring real divisional accountability to the goat locker's conversations are the ones who receive the mess's full institutional support. The ones who arrive with a 'I already know this' posture leave that first year with a different kind of standing.
  • Division-level CSMP and PMS posture defensible at CO level — zero LCPO-attributable CAT-I INSURV findings on the IC system suite during your tenure.
    CAT-I INSURV findings on IC systems are the visible permanent record of an LCPO's material maintenance stewardship. The way to avoid them is not to be lucky during the survey — it is to run the pre-INSURV self-assessment as though the surveyors are watching, find the findings yourself, and correct them before the survey. The LCPO who can say 'we self-identified and corrected seven potential findings in the six weeks before the survey' is briefing a posture, not a result.
  • Surface Warfare device current and backed by an actual qualification record; you brief around it when the division is watching.
    The SWS device on an ICC's uniform is a visible signal to the division that the chief is invested in the ship, not just the work center. Keep the qualification record current through the tour — annual re-qualification requirements where they exist, new-ship qualification when you check aboard a different platform. The chief who says 'I have the device' but cannot answer a ship's systems question in front of the division is wearing a credential, not carrying one.
  • Pipeline producing 1+ NEC-pipeline entry, LDO/CWO, commissioning, or NWAE selectee per year.
    The pipeline output the wardroom can name without asking you for the list is the output that appears in the LCPO's end-of-tour evaluation. Track the pipeline annually: one school nomination per year, one LDO/CWO packet counseling per cycle, one NWAE study plan on the table per cycle. The ICC who produces three IC1 Chief selectees and one LDO accession in a 24-month sea tour is building a measurable professional legacy.
  • Zero Chief-level integrity incidents. One ends the career permanently and the goat locker already knows the math.
    The ICC's integrity standard is not the same as the IC2's integrity standard — it is higher. The mess, the wardroom, and the command read the LCPO's integrity in every CSMP number, every eEVAL narrative, every personnel recommendation, and every 0200 brief to the XO. The ICC who rounds up a CSMP number, softens a negative eEVAL because the sailor is his 'guy,' or passes a verbal authorization as documented is eroding the institutional trust the goat locker runs on.

Technical Mistakes — Concrete Consequences

  • Treating the goat locker as a social club rather than a working leadership institution.
    The Chief's Mess is the senior enlisted leadership platform of the ship — the chiefs who do not contribute to its professional development program, its accountability functions, and its enlisted climate work leave the mess carrying their anchor without the mess's institutional investment behind them. The IC1s in the division read the difference between a chief who is in the mess and a chief who is of the mess.
  • Stopping personal PT discipline because the anchors are pinned.
    An ICC who fails the semi-annual PRT generates a flag the XO sees, the CMC brief includes, and the Chief selection board reads in the evaluation package of the next ICCS/ICCM nominations from that command. The physical readiness standard for an ICC is not lower than for an IC2 — it is more visible because the division watches whether the LCPO who demands maintenance discipline maintains his own.
  • Allowing an IC1 LPO to run a division with degraded PMS discipline because he is 'almost a Chief.'
    The ISIC inspector finds the degraded CSMP posture during the work-center assessment. The finding attributes to the IC1 as the LPO and to the LCPO as the division chief. 'He was almost a Chief' does not appear in the ISIC finding report; 'ICC [name] served as LCPO of the IC division during the assessed period' does.
  • Going public with a disagreement with the department head or CO at the department sync level.
    The wardroom and the division read the alignment between the LCPO and the DH in every interaction at the department sync. A chief who surfaces a disagreement publicly rather than taking it into the chief's office is signaling to every IC in the division that the chain of command is negotiable. The next time an IC2 goes around the IC1 LPO to the DivO, the LCPO is the one who has to explain why that is unacceptable — while the division watches.
  • Treating battle-lantern operability as administratively low-priority.
    The battle-lantern zone that has dead batteries in the main engine room flooding scenario is not a performance metric on an INSURV assessment — it is a safety incident with a causal chain that runs through the IC work center's PMS calendar, the LPO's zone inspection record, and the LCPO's oversight of both. The INSURV finding report names the LCPO.

Career Decisions at This Rank

  • ICCS (Senior Chief) selection — is this a goal and what does the record need?
    ICCS selection is the NWAE path extended into the senior enlisted tier — but it is not just a test score. The ICCS selection board reads the ICC record for: LCPO-level pipeline output (Chief selectees, LDO/CWO accessions, NEC pipeline), INSURV and ISIC posture across multiple sea tours, Chief's Mess contribution (SEA completion, initiation mentorship, goat locker professional development leadership), and the CMC/CO recommendation. The ICC who starts building the ICCS record on ICC pin-on day — not on ICCS eligibility day — is the one whose record briefs cleanly when the board convenes.
  • Senior Enlisted Academy — timing and priority.
    SEA is the professional development milestone for ICC/ICCS; the ICCS selection board reads it as a positive marker. The question is timing: SEA attendance takes the LCPO off the ship for several weeks, and the right time is when the division has the IC1 LPO bench strength to run without daily LCPO involvement — which is itself a measure of how well the LCPO has built the division. The CMC coordinates the nomination; the conversation about timing should happen in the first six months of the ICC tour, not when the CMC asks if you have applied.
  • Command Senior Chief billet vs. continuing as LCPO — eligibility opens at ICCS.
    The Command Senior Chief (CSC) billet is available to ICCS/ICCM selectees and focuses on command-climate leadership, enlisted welfare, and the CMC-level advisory function to the commanding officer. For an ICC approaching the ICCS gate, understanding the difference between the LCPO path (technical/maintenance/personnel leadership for a specific rate and division) and the CMC path (command-wide enlisted climate and advisory function across all rates) is the decision that shapes the last five to ten years of the career. Neither path is universally better — the right answer depends on whether your leadership strengths are rate-specific technical mentorship or command-wide enlisted climate work.
  • Post-Navy transition planning — the ICC who starts at 15 years is two years ahead of the one who starts at 18.
    The IC rate's post-Navy market is real: marine electronics integrators (NASSCO, Bath Iron Works, HII, L3 Technologies), NAVSEASYSCOM and PEO Ships GS billets, and the DoD contracting base that supports fleet IC system maintenance. The ICC who has cultivated relationships with the NAVSEASYSCOM technical representatives, the FTSC team leaders, and the shipyard engineering contacts over the course of a 20-year career is the one who gets the call before the resume goes in. Build the network during the tour — not because it feels strategic, but because these are the professionals you will work alongside for the next 20 years after the Navy.

How the Seat Varies by Unit Type

  • Surface Combatant (DDG, CG) — deploying
    The highest-visibility LCPO billet in the IC rate. A DDG LCPO runs a work center of 8-15 ICs through deployment cycles, TSTA events, and INSURV workups that are visible at Type Commander level. The eEVAL profile from a deploying DDG LCPO billet is the strongest ICCS/ICCM record in the surface IC community. The operational demands are real: 0200 XO calls, GQ drill cycles, and 7-month deployment maintenance windows where the CSMP cannot slip.
  • Amphibious Ship (LHA, LHD) — major-hull LCPO
    A larger hull with a larger IC suite — more announcing zones, more gyrocompass repeater networks, more battle-lantern inventory. The LCPO on a major amphibious hull may have a larger division than a DDG LCPO and a correspondingly larger eEVAL and CSMP footprint. The amphibious mission profile (well-deck operations, MEU deployments, TRAP/NEO support) creates additional IC operational demands the destroyer community does not have.
  • Shore Technical Command (FTSC, NAVSEASYSCOM Det)
    The ICC who takes an FTSC or NAVSEASYSCOM detachment billet as LCPO is building cross-platform IC system expertise and the NAVSEASYSCOM network simultaneously. The LCPO role at a technical command involves managing field service teams rather than a shipboard division — the accountability structure is different, the eEVAL profile is different, and the INSURV exposure is indirect. The post-Navy contractor network built from an FTSC or NAVSEASYSCOM det tour is the strongest in the IC rate.
  • Surface Force Staff (TYCOM, Group Staff)
    An ICC on a Type Commander or surface group staff serves as a senior enlisted IC technical voice in a planning and advisory function. The billet involves fewer direct LCPO responsibilities and more program-level advisory work — NEC source-rating management, INSURV program review, fleet-wide IC system material condition assessment. The record-building implications for ICCS selection are different from a sea-billet LCPO — the Chief's Mess and the CMC read a staff tour differently from a ship tour, which is not a negative but is a different kind of record.

What Good Looks Like at This Rank

The good ICC is the LCPO the CO calls by name in the readiness brief and the goat locker defends in the mess. His IC system suite briefs without caveats before an INSURV survey — not because he cleaned it up in the two weeks before the surveyors boarded, but because the CSMP is clean every week that it needs to be read by anyone, which is every week. The IC2 he promoted to IC1 last cycle picked up Chief on the subsequent board. The LDO packet he mentored was selected. The NWAE selectees from his division are on the advancement list the command cites in the rate-health brief. The thing the ICCS/ICCM selection board actually reads in the ICC's record is not the eEVAL summary — it is the answer to 'what did his division produce and what condition was the IC system suite in when he left?' The ICC whose answer to both questions is specific and measurable — Chief selectees named, LDO accessions documented, INSURV posture clean across two surveys, battle-lantern operability rates above threshold through two deployments — is the one the board recommends without qualification. The thing the IC1s in the division remember about the good ICC five years after the tour ends is not that he was smart or technically proficient. It is that he held the line. That the CSMP numbers were never wrong because he verified them personally. That the eEVAL he wrote about them was specific enough to defend in a wardroom board. That when the 0200 call came in about the 5MC loop, he was in the IC room in 20 minutes with the right TM section and the resolution timeline. That is the standard that follows the rate's chiefs into the next generation.

Preview — The Next Rank

ICCS (Senior Chief Petty Officer) and ICCM (Master Chief Petty Officer) are the ranks where the IC rate stops assigning you to a division and starts assigning you to a staff, a squadron, or a command-level advisory function. The LCPO accountability that defined the ICC tour becomes the baseline — the ICCS/ICCM is expected to have already demonstrated LCPO-level excellence, and the new question is whether the officer can advise the department head and the CO on enlisted matters across the entire command, not just the IC division. The INSURV posture brief at ICCS/ICCM level is a fleet-level or Type Commander-level brief, not a ship-level brief. The NEC pipeline management conversation shifts from 'who in my division is eligible for the advanced course' to 'what is the rate-wide NEC pipeline health and what is the NAVSEASYSCOM recommendation.' The scale changes; the discipline required to produce accurate numbers does not. The post-Navy transition plan that the good ICC has been building for five years becomes an active project at ICCS/ICCM. The ICs you produced for marine electronics integrators, NAVSEASYSCOM GS billets, and DoD contractors over a 24-year career are your professional network. The ICCM who cultivated those relationships is the one who lands the senior technical role — not because of nepotism, but because 24 years of demonstrated IC system expertise and technical leadership is exactly what those organizations need and rarely find.
