Hospital Corpsman

You are an apprentice corpsman. The ward already calls you Doc and you have not earned it yet — the next 18 months are the down payment on the rate.

Fresh out of "A" School at METC Fort Sam Houston, you rotate through whatever billet the command needs filled — ward, sick call, immunizations, central supply, optical, pharmacy window, or the watch bill at a small clinic or BAS. You take vitals, draw labs, give shots, restock the crash cart, sterilize instruments, and run the unglamorous tasks the HM2s and HM1s do not have time for. You stand duty in scrubs at the MTF or in cammies with the unit, you study for sea-and-shore qualifications (821x PQS, EOOW or aid station-specific quals), and you start the bibliography for the next NWAE cycle. Whether you end up blue-side on a ship, green-side with a Marine battalion, or in an MTF clinic depends on orders, your LPO, and how visibly you carry yourself in the first 90 days.

• 01Take a clean set of vitals — BP, HR, RR, SpO2, temp, pain score — and chart them in MHS GENESIS or the local paper SOP without correction.
• 02Run a sick-call screening to triage: who needs the PA / MO now, who is RTD, who is light duty, who is SIQ — and never overstep that line.
• 03Start a peripheral IV in a routine patient and a saline lock; draw labs by venipuncture without bruising the chief who teaches the class.
• 04Stock and inventory an aid bag, treatment cart, or sick-call room to unit SOP — expiration dates, broken seals, controlled-substance log, all caught before the LPO walks in.
• 05TCCC at the All Service Member tier — MARCH-PAWS, CAT tourniquet high-and-tight in under 25 seconds, NPA, NCD, hypothermia prevention.
• 06Master the HM Pledge and the chain of command cold — sick-call patients and the LPO both ask, in different ways.

• —NAVMED P-117 — Manual of the Medical Department (MANMED). The HM bible; live in the chapters that touch your billet.
• —NAVMED P-5010 — Manual of Naval Preventive Medicine (you will be quoted from it on every food-service or water-quality inspection).
• —JTS / CoTCCC Tactical Combat Casualty Care Guidelines, current edition (jts.health.mil).
• —Hospital Corpsman NRTC / Rate Training Manual (the legacy NAVEDTRA HM rate training manual) — start the bibliography now.
• —NAVPERS 18068 Vol II — Manual of Navy Enlisted Manpower and Personnel Classifications (the NEC catalog for 8404, IDC, SARC, SAR, Submarine).
• —OPNAVINST 6110.1 — Navy Physical Readiness Program (your PRT/BCA standard).

• —BLS (Healthcare Provider) currency from day one and kept current — lapse it and you are off the duty rotation.
• —All NWAE-eligible PQS / 301-series watch quals signed off on the timeline your LCPO sets — the slow corpsman becomes the slow HM3 candidate.
• —PRT Good Low or higher; BCA in standard. The senior corpsmen notice who carries the bag on a 5-mile movement and who falls out.
• —NWAE study habit established — eligibility cycle for HM3 is faster than fresh corpsmen believe; pull the current Bibliography for Advancement Exam Study (BIB) and own it.
• —Sick-call documentation rate: every patient encounter charted, signed, and routed to the provider the same shift. No "I will catch up Friday."

• —Charting outside your scope or after the fact. The PA / MO signs off your screening; if it is not in the record by end of watch the command cannot defend the encounter on a tort claim five years later.
• —Storing expired meds or a broken seal on the controlled-substance log. One bottle ends the inspection and your name goes on the chit.
• —Treating mental-health intakes as embarrassing. Direct Access, Fleet & Family, and the unit BH pathway exist — using them is the standard, not a black mark.
• —Pushing a shipmate to "tough it out" because the LPO wants the muster number green. You are the medical advocate, not the chief's yes-doc.
• —Sharing patient details outside the encounter. HIPAA violations at HN paygrade end careers before they start; the BUMEDINST 6300 series is real and the command privacy officer is watching.

The good HN is the corpsman the LPO sends to draw blood on the cranky retiree commander because the labs will come back clean and the patient will leave smiling. By month nine the PQS is done, BLS is current, and the LCPO is asking which "C" school pipeline you want — 8404 with the Marines, submarines, SAR, or staying blue-side for IDC down the line.

You are a petty officer now. The crow on your sleeve says you own a piece of the watch bill, a chunk of the training plan, and at least one HN who is watching how you wear it.

You own a shift in the BAS, the ship's medical department, the MTF clinic, or the sick-call rotation. You train HNs on PQS line items, run immunization clinics, manage a sub-account on the medical AMAL/ADAL or shore-equivalent supply, and execute the LPO's training plan instead of just attending it. If you are green-side after FMTB, you are the battalion line corpsman or the H&S Company aid station bench — kit ready, TCCC dialed, and rucking with the Marines whether they like having a sailor in the line or not. The "C" school conversation gets serious: 8404 if you came in blue-side and want the FMF tab, IDC packet long-range, submarine pipeline, SAR, or PMT (8409). Pull the current NAVADMIN for advancement quotas and the current NEC source ratings before you fall in love with a path.

• 01Run sick call as the screener for 30-80 patients a shift — clean triage, clean charting, clean handoff to the PA / MO; know when to escalate and when to RTD.
• 02Execute a 9-line MEDEVAC / casualty-evacuation call on a real patient, with the radio in your hand, the grid right, and the receiving facility actually expecting the patient.
• 03Run a TCCC lane for line Marines or shipmates — instructor-level CAT/junctional/wound-pack/airway with realistic scenarios, not slide-only.
• 04Manage the controlled-substance log on your shift — count, sign, secure, reconcile, and never leave it open. Discrepancies are command-level events.
• 05Operate the unit's electronic health record (MHS GENESIS, or the deployable version your platform runs) without your LPO double-checking your encounters.
• 06Stand BAS / sick-call watch as senior corpsman on duty during liberty hours — own the call to wake the duty MO at 0200 if it is real, and own not waking him if it is not.

• —NAVMED P-117 (MANMED) — own the chapters that touch your billet (sick call, immunizations, occupational health, deployment health, behavioral health).
• —JTS / CoTCCC TCCC Guidelines — current edition; you teach this, you do not just take it.
• —BUMEDINST 6300 series — clinical and patient-care policy from BUMED; the rules your CMIO / quality NCO quote on every inspection.
• —NAVPERS 18068 Vol II — the NEC catalog; read the entries for 8404, L09A submarine, L13A IDC, 8425 SAR, 8427 SARC, 8409 PMT before you talk to the career counselor.
• —Hospital Corpsman NWAE Bibliography (BIB) — current cycle. Pull from MyNavyHR / NETC; the BIB is the test, the test is the BIB.
• —FMSS / FMTB student handbook if you are 8404-track — the FMF qualification piece (FMF/E warfare device) is a real packet you build, not a checklist someone hands you.

• —NWAE for HM2 prep on the LCPO's timeline — the corpsman who walks into the exam cold is the corpsman who watches the slate from the bench.
• —PRT Good Medium or better; BCA in standard. Green-side corpsmen are held to the unit's PFT/CFT cycle on top of PRT — pass the Marines' standard or you are visible for the wrong reason.
• —BLS, plus ACLS or PHTLS / TCCC instructor depending on billet — currency tracked in MEDPROS / equivalent and on the LPO's tickler.
• —At least one NEC pipeline packet in motion (8404, submarine, SAR, PMT, ATT/8483 aerospace) — or a documented reason you are still building the next one.
• —eEVAL trait average that supports an EP if the command wants to push you — your LPO knows it weeks before the EVAL drops.

• —Treating a controlled-medication count as a paperwork drill. One missing vial in a narc box ends the inspection, opens a JAGMAN, and follows your name on every future EVAL.
• —Closing an encounter as RTD because the chief or gunny wanted the number. The injury surfaces on the next field op or the VA fights the sailor for it in year ten — and your charting is what gets read.
• —Skipping the BH referral because "the captain does not like the numbers." MANMED and BUMEDINST are clear; the corpsman who hides a referral wears the consequence when the suicide attempt happens.
• —Going around the LPO to the LCPO or the MO. The medical chain runs through the LPO for a reason; the chiefs notice, fast.
• —Posting OPSEC-relevant photos from the BAS or sub patrol. Patient on the table, unit insignia, deployment timeline — the BUMED IG and the OPSEC officer read social media, and so do adversary collectors.

The good HM3 is the corpsman the LPO trusts to run sick call when the LCPO is on leave and the MO is in the OR. The HNs come to him with the question before they ask the chief; his charting is clean; his TCCC class is the one the gunny actually wants for the platoon. He is on the bench for the next NEC slate before his first eEVAL closes.

You are the working senior corpsman. The HM3s call you LPO whether the title is on your collar or not, and the chief is mentoring you toward the anchors he will pin in two boards.

You run a section — sick-call cell, immunization clinic, ward team, BAS line, ship's medical department night shift, or a Marine company's aid station as the senior corpsman embedded. You train and qual-sign two-to-four HM3s and HNs, build the section's training plan, manage your slice of the AMAL/ADAL, sit on the LCPO's synch as the section lead voice, and write the section's portion of the medical annex when the unit publishes an OPORD or NAVMSG. NEC-coded billets define the seat: 8404 with a Marine battalion BAS, L09A submarine corpsman on patrol, L13A IDC candidate building the packet, 8425 SAR rotary-wing, 8427 SARC pipeline if selected. The NWAE for HM1 is no longer abstract; the eEVAL ranking against your peer HM2s actually starts to matter for the next slate.

• 01Run a BAS or ship's sick-call line as the senior enlisted medical voice on shift — triage, treatment, charting, controlled-med oversight, handoff to the MO / IDC / PA without the provider rewriting your work.
• 02Operate independently when the platform requires it (LCAC det, sub patrol, embedded with a Marine company, small ship) — within IDC / PA reach-back, but you are the on-scene provider until they answer the radio.
• 03Run a battalion-level or ship-wide MASCAL drill as the senior corpsman in the response — triage tags, START, evac sequencing, blood plan if the unit is fielded with cold-stored whole blood.
• 04Build and sign off PQS / 301 line items for HM3s and HNs as the qual signer — your signature is the standard, and your LCPO reviews what you put your name on.
• 05Write the medical input to a company / ship / boat OPORD — casualty estimate, evac chain, blood, MASCAL, classes of supply — clean enough that the BAS officer or MEDO does not have to rewrite it.
• 06Mentor an HM3's NEC / "C" school packet from idea to selection — 8404, submarine, IDC application, SAR, SARC, PMT — and be honest about the lifestyle cost of each path.

• —NAVMED P-117 (MANMED) — fluent in the chapters that drive your billet, including the deployment health and occupational health pieces you sign for.
• —NAVMED P-5010 — Manual of Naval Preventive Medicine (food service, water, vector, occupational — the inspection you have to pass cold).
• —BUMEDINST 6010 series — clinical and quality management; you live the documentation standards on every encounter.
• —JTS Clinical Practice Guidelines (jts.health.mil) — current; you teach the line off these, you do not invent your own SOP.
• —NAVPERS 18068 Vol II — NEC catalog; you mentor packets off this and the current NEC source-rating message.
• —NWAE Bibliography for Advancement (BIB) for HM1 cycle — current; build a study plan with milestones, not a stack of PDFs.

• —NWAE for HM1 prep documented on the LCPO's timeline; the candidate who passes EAW (Enlisted Advancement Worksheet) clean and walks in with a strong BIB study log is the candidate the chief defends in the wardroom.
• —NEC awarded or in-pipeline (8404, L09A submarine, L13A IDC selection in motion, 8425 SAR, 8427 SARC) — the HM2 without an NEC pathway is visible at the next ranking board.
• —PRT Good High or better; BCA in standard; FMF / Submarine / Aviation / EXW warfare device pinned where the billet allows (FMF/E for 8404, SS/SW for sub, EXW for expeditionary).
• —eEVAL trait average and ranking that supports EP/MP recommendation; your LCPO knows your number before the EVAL board reads it.
• —Section certification rates — TCCC, CLS, BLS, ACLS where required — at or above command average without exception.

• —Letting an HM3 close encounters without spot-checking. Your sign-off is the standard; if the chart is wrong, the LCPO comes to you first and the MO comes to you second.
• —Skipping the controlled-substance inventory because the watch turnover was rushed. The next IG / BUMED inspection finds it, the JAGMAN starts, and the petty officer who broke the chain is named.
• —Practicing past your scope under stress and not documenting after. Your NEC scope (especially 8404, IDC-candidate, submarine) is real and broader than civilian EMT-B — but it is bounded, and the chart has to defend what you did.
• —Treating the FMF / SS / AW warfare device as a paperwork drill. The qual board chiefs ask hard questions; an HM2 who walks in cold and fails embarrasses the section and shows up on the LCPO's tickler.
• —Going around the LCPO to the senior medical officer. The medical chain runs through the chief; the goat locker hears about it the same day, and your Chief packet feels it three years later.

The good HM2 is the corpsman the LCPO names when the BAS officer or MEDO asks who is running the night shift. His section's certification numbers brief without caveats; his HM3 has a packet on the table; his eEVAL bullets are action-result-impact, not generic medical filler. He sits the HM1 NWAE on a study log the chief can defend, and the NEC pipeline he is in is the one the LCPO recommended without prompting.

You are the LPO. The chief is grooming you for anchors; the wardroom calls you by name; the HM2s and HM3s watch how you carry the section the way you used to watch the chief.

You are LPO of a department, ship's medical division, battalion BAS, MTF section, submarine medical department (if you are the senior corpsman aboard a sub without an IDC), or specialty clinic — 10-25 corpsmen and a piece of the command's medical readiness. You write four-to-six eEVALs per cycle for HM2s and HM3s that pick the next NWAE slate. You build the department training plan, defend the readiness brief at department head sync, manage controlled-substance accountability at the LPO level, and mentor at least one corpsman a year into IDC / 8427 SARC / submarine / commissioning (Seaman to Admiral, MECP, Nurse Corps) selection. The Chief board packet conversation is no longer abstract — your LCPO is editing your record, your eEVAL profile is being built, and the warfare device on your blouse matters more than any single qualification you have ever earned.

• 01Run a department-level training and readiness program — TCCC, BLS, ACLS, PHTLS, immunizations, BCA, dental, PHA — at or above command average with reporting the MEDO can defend.
• 02Operate as the senior corpsman on an independent platform when the billet requires it — small ship, sub patrol if NEC-coded, embedded Marine company on FMF orders — with IDC / PA / MO reach-back but day-to-day clinical authority on scene.
• 03Manage controlled-substance and high-risk medication accountability at the department level — chain-of-custody documentation that survives a no-notice BUMED IG or Joint Commission look.
• 04Build and defend a department readiness brief to the MEDO / BAS officer / department head — MEDPROS-equivalent / medical readiness reporting, dental, PHA, individual medical readiness (IMR), behavioral health waitlist — without the wardroom rewriting your numbers.
• 05Mentor an HM2's NWAE / NEC / IDC / commissioning packet from idea to selection — and counsel honestly when the path is wrong for the sailor.
• 06Write an eEVAL block the senior rater can defend at a wardroom board — measurable accomplishments, named outcomes, the language the Chief board actually reads.

• —NAVMED P-117 (MANMED) — fluent across the chapters that govern your department; you are now the LPO the HM2s come to with the chapter question.
• —NAVMED P-5010 — Preventive Medicine (you sign the inspection sheets; you brief the gaps).
• —BUMEDINST 6010 / 6300 / 6320 series — clinical, quality, and patient-care policy as it applies to your platform.
• —OPNAVINST 6110.1 — Navy PRT; you defend the department's PRT/BCA posture and you live it.
• —JTS Clinical Practice Guidelines — full library; you teach off them and you defend command training against them.
• —NAVPERS 18068 Vol II + the current NEC source-rating NAVADMIN — you build the packet pipeline off the current cycle, not the one from two years ago.

• —Chief board packet under construction with the LCPO's eye on every line; eEVAL profile defensible at wardroom / command level; warfare device pinned and current.
• —Department medical readiness reporting (IMR / dental / PHA / immunizations) defensible at MEDO / department head level — every cycle, no caveats.
• —Controlled-substance accountability clean — zero unresolved discrepancies, audit trail intact, witness signatures matching watch bills.
• —Pipeline output — IDC / SARC / submarine / commissioning / NWAE — producing at least one selectee per year from your department.
• —NWAE for Chief is replaced by the Chief Petty Officer selection board; the package is built across the year, not the week before submission. The LCPO defines the cadence.

• —Briefing IMR / readiness numbers you have not personally validated. The MEDO catches it once and your Chief packet feels it permanently.
• —Letting a senior HM2 carry the controlled-substance reconciliation because "he is your guy." When he transfers, the gap surfaces and the LPO's name is on the JAG.
• —Confusing seniority with clinical authority. The MO / PA / IDC owns the clinical call; you own enlisted execution, training, and the documentation that defends the encounter.
• —Going around the LCPO to the MEDO or department head. The chiefs talk; the next Chief board sees the pattern.
• —Treating the Seaman-to-Admiral / MECP / Nurse Corps mentoring conversation as transactional. The sailors you put through commissioning at this rank build the bench BUMED quotes a decade from now — counsel honestly about ADSO, OCS, and the seat they actually want.

The good HM1 is the LPO the LCPO trusts to run the department for a week without daily check-ins. His readiness numbers brief without caveat; his eEVALs select corpsmen above expectation; his pipeline produces IDC, SARC, submarine, and commissioning packets the wardroom signs without rewriting. He sits the Chief selection board with a record that reads itself.

You are a Chief. The gold-fouled anchors mean the goat locker is yours, the wardroom asks you by name, and the entire department reads the command's mood off how you stand at quarters.

The job changes more between HM1 and HMC than at any other promotion. As LCPO of a department — medical division on a ship or boat, BAS at a Marine battalion (8404 LCPO), specialty clinic at an MTF, BUMED detachment, training command — you run 15-40 corpsmen and you own enlisted execution from the deckplate up. You write Chief-quality eEVALs that pick the next HM1 and HMC slate; you sit at department head sync as the senior enlisted medical voice; you walk the deck during a real-world contingency, MASCAL, or readiness inspection and identify broken systems before the surveyor does. You build the next LPO. You mentor the next IDC / SARC / submarine / commissioning candidate. You enforce the standard, in uniform, every day, while the deckplate watches whether your liberty habits match your at-sea posture.

• 01Run an LCPO's mess of corpsmen — accountability, training, readiness, discipline, family, finance — with weekly cadence the MEDO and the department head can predict.
• 02Defend the department's medical readiness, controlled-substance accountability, BUMED-mandated training (TCCC, BLS, ACLS, PHTLS, BH first aid), and inspection posture at command-level synch without your numbers being rewritten.
• 03Walk a real-world MASCAL, mass-casualty drill, or BUMED IG visit as the senior enlisted medical voice on scene — your AAR is what the wardroom briefs up the chain.
• 04Mentor four-to-six HM1s into Chief-board-competitive candidates; mentor at least one IDC / SARC / submarine / commissioning / Nurse Corps packet to selection per year.
• 05Operate as the senior enlisted medical voice during a deployment, patrol, MEU, or contingency — including the call to wake the CO at 0200 when the medical posture has actually shifted.
• 06Translate Surgeon General / BUMED / Type Commander medical strategy into deckplate decisions the corpsmen rehearse without rewording the message.

• —NAVMED P-117 (MANMED) — full familiarity; you are the LCPO the JOs come to with the policy question.
• —BUMEDINST 6010 / 6300 / 6320 / 6440 / 6710 series — clinical, quality, controlled-substance, and patient-care policy across the BUMED catalog.
• —OPNAVINST 6110.1 — PRT (you defend it across the department).
• —JTS Clinical Practice Guidelines — current library, indexed in your shop.
• —MILPERSMAN — fluent in the articles that govern enlisted personnel actions (advancement, retention, separation, NJP) at HMC-level visibility.
• —CPO 365 / CPO Initiation guidance — the wardroom and the goat locker hold you to it, even after the anchors are pinned.

• —CPO Academy / Chief's Mess transition complete; standing as a Chief in the mess at the deckplate level — not a Chief in title alone.
• —Department-level medical readiness, controlled-substance accountability, and BUMED training rates defensible at department head and command level, every cycle.
• —eEVAL profile and ranking that picks the next HM1 and HMC slate from your shop — measured by which sailors actually select.
• —Pipeline producing 1+ IDC / SARC / submarine / commissioning / Nurse Corps selectee per year.
• —Zero Chief-level integrity incidents — fraternization, financial, HIPAA, OPSEC. One ends the career permanently.

• —Mistaking the goat locker for a private club. The mess is a working leadership platform; chiefs who treat it as social will be the ones the department reads as off-mission.
• —Stopping personal PT and BCA discipline because "I am a Chief now." Sailors read the deckplate harder when the anchors go on, not less.
• —Letting an HM1 LPO run a bad department because he is "your guy" or "almost a Chief." The MEDO and the CMC see the climate first and the slate gets read.
• —Going public with disagreement with the MEDO or the CO. The disagreement happens in the office; you walk out aligned. The goat locker enforces this without the wardroom asking.
• —Treating the IDC / SARC / submarine / commissioning mentoring as a checkbox. The careers you build at this rank shape BUMED's enlisted bench for the next decade.

The good Chief Hospital Corpsman is the LCPO the CO calls by name and the goat locker defends in the mess. His department briefs without caveats, his HM1s pick up Chief, his commissioning and NEC packets select at rates above the platform average, and his deckplate posture matches his liberty posture. He is on the Senior Chief slate before the CMC has to ask.

You are the senior enlisted medical voice in a department, command, or staff. The CO names you in the slide. The deckplate watches whether you still walk the line.

As HMCS or HMCM you run the senior enlisted medical posture for an MTF department, a medical battalion, a CSG / ESG / MEU / TYCOM staff, a BUMED detachment, or sit as a Command Master Chief (CMC) or Chief of the Boat (COB on submarines) where the path opens. You write fewer eEVALs but they are the ones that pick the next Chief and Senior Chief slate. You sit at command-team synch as the senior enlisted voice on every enlisted medical decision — accession, training, retention, credentialing, discipline. You translate Surgeon General / BUMED strategy into command-level talent decisions. You build the next CMC / COB / SEA selectee. You start the post-Navy market plan 24-36 months out — credentialing translation, civilian RN/Paramedic bridge, federal hiring, defense industry, healthcare administration — because the bench you leave behind decides whether the goat locker remembers your name.

• 01Run a senior-enlisted command climate across a medical department or command that produces certified corpsmen, IDC/SARC/submarine selectees, and commissioning accessions at rates above the type-command average.
• 02Brief the CO, MEDO, TYCOM, or BUMED on enlisted medical readiness and risk in language the flag officer can defend at the next echelon — without rewriting.
• 03Sit on Chief selection board panels, command CMC slates, and senior-enlisted credentialing panels with the discipline and confidentiality the convening authority requires.
• 04Translate BUMED / Type Commander / OPNAV-led medical strategy into enlisted talent management decisions at the unit and across the rate.
• 05Run a real-world contingency, deployment, or mass-casualty response as the senior enlisted medical voice — and your AAR is what BUMED reads in the lessons-learned.
• 06Run a Red Cross / casualty notification with the dignity it requires. You are the face the family sees.

• —NAVMED P-117 (MANMED) — full library; you are quoted from it more often than you quote it.
• —BUMEDINST series across clinical, quality, controlled-substance, credentialing, and personnel — you are the LCPO of LCPOs.
• —MILPERSMAN — fluent on enlisted personnel actions at the senior-enlisted threshold; you are in the room for NJP, separation, and high-visibility cases.
• —OPNAVINST 1306.2 series — detailing and assignment policy as it applies to senior-rate HMs.
• —Senior Enlisted Academy (SEA, Naval War College Newport RI) reading list and CPO/CMC Symposium materials — you consume doctrine and translate it down.
• —BUMED, Surgeon General, and Type Commander policy memos / NAVADMINs — current; pull each one as it drops, not from a stale folder.

• —SEA fellowship or USAFCSEL / equivalent senior-enlisted PME complete before competing for command CMC / COB slate.
• —Command-level medical inspection (BUMED IG, Joint Commission, TYCOM) passed without senior-enlisted-attributable findings during your tenure.
• —Commissioning, IDC, SARC, and submarine accession pipeline producing 1+ selectee per year from your command — and the wardroom can name them.
• —eEVAL profile that the senior rater can defend at command and TYCOM level — your rated chiefs are picking up Senior Chief and Master Chief on schedule.
• —Zero senior-enlisted-level integrity incidents — financial, fraternization, HIPAA, OPSEC. One ends the career permanently and there is no recovery at this paygrade.

• —Pretending to be the senior clinical voice on a topic where you are out of date. Senior corpsmen lose authority by faking depth — the MEDO and the JOs see it inside the same brief.
• —Letting a Chief-led department drift on credentialing or controlled-substance accountability because "the wardroom will catch it." You own the enlisted execution at the unit roll-up; the inspection finds it under your name.
• —Treating the commissioning / IDC / SARC mentoring conversation as transactional. The careers you support at HMCM build the enlisted medical bench BUMED depends on for the next decade and beyond.
• —Going public with disagreement with the CO, MEDO, or commodore. Take it in the office. Walk out aligned. The goat locker and the wardroom both enforce it.
• —Confusing the warm-up to retirement with the job. Until you walk out of the formation for the last time, the formation is your job, and the deckplate reads which one you are working.

The good Master Chief Hospital Corpsman is the senior enlisted medical voice the CO, MEDO, and TYCOM all name without thinking. His department or command's enlisted medical slate is the one BUMED quotes in policy memos; his commissioning and NEC accession rate is in the upper third of the rate; his rated chiefs pin Senior Chief and Master Chief on schedule. When he retires the goat locker remembers the standard he left, not the position he held.
