Morning review of the AWP report and CASREP list — identify any new CASREP supply requirements and initiate requisitions before the 0800 brief. Process any overnight-received material, verify condition, post transactions, and route to maintenance. Spend mid-morning on DIFM follow-up — call or message each shop that has overdue returns and document the contact. Afternoon is demand analysis review, checking whether any high-consumption items should be added to the AVCAL, and training the junior Marines on discrepancy resolution. Late afternoon is the daily status call with the MALS SMD to talk through backordered NMCS parts.

Monday: review and certify the requisition register with the supply chief — every document accounted for. Tuesday: DIFM cage audit — hands-on verification that every item receipted to maintenance has a documented status. Wednesday: NMCS/AWP brief preparation for the Aircraft Maintenance Officer's Thursday staff meeting. Thursday: participate in or brief the aircraft readiness meeting — know your numbers cold. Friday: AVCAL review, identify any items burned down to below minimum allowance, initiate replenishment. Monthly: full physical inventory of assigned storage areas to NAVSUP P-485 standards.

Demand analysis is the E4 skill that separates the good from the average — understanding which parts your aircraft consume consistently, identifying NSNs that should be on the AVCAL but aren't, and making defensible requisition quantity decisions. CASREP process management requires you to know exactly which supply requirements are tied to a CASREP, maintain daily contact with the supporting supply activity, and report status accurately to the Aircraft Maintenance Officer. DIFM accountability demands you know every item receipted to maintenance, track due-back dates, and escalate overdue returns before they become a survey. Training junior Marines on MILSTRIP means you must be able to explain every field, every code, and every error message from first principles. SHOREREC/Navy ERP reconciliation — knowing how to find and resolve posting errors — becomes an E4 responsibility.

NAVSUP P-485 Volume II chapters on aviation support are the technical backbone of your CASREP and NMCS procedures — know which supply status codes obligate you to escalate versus which you can resolve at the unit level. COMNAVAIRFORINST 4790.2 Series Chapter 15 covers the supply-maintenance interface and defines what triggers a CASREP from the supply side versus the maintenance side — understanding it helps you have technically credible conversations with maintainers. MCO P4400.150 priority designator tables live in your head at this rank, not on a reference card. The Wing/MALS OPNAV 4790/CK forms are your daily operational documentation — know how to read every field.

At E4, standard is zero unresolved discrepancies on your DIFM log for more than 10 days without documented escalation. Priority designators applied correctly 100 percent of the time — the Supply Officer should not be correcting your codes. NMCS requisitions followed up every 24 hours, not 72. Junior Marines in your section should be improving, not making the same mistakes after two weeks of your training. Inventory accuracy in your assigned area should survive a surprise spot-check.

Processing a receipt against the wrong document number because two requisitions for the same NSN were open simultaneously — the part goes on the books twice and one requisition stays open as an unresolved due-in, creating a phantom debt against the unit's obligation ceiling. Misclassifying a repairable item as consumable on a DIFM transaction eliminates the turn-in requirement and creates a missing asset that shows up at annual inventory. Incorrect condition code assignment on a survey — marking a repairable asset 'H' (condemned) when it should be 'F' (unserviceable repairable) routes it to disposal instead of the repair facility and the Government loses the asset.

If you're considering re-enlistment, the decision between staying at a fleet squadron for a second tour versus competing for a MALS billet is the most consequential career move an E4 can make in 6672 — MALS billets are technically harder and the promotion competition is tighter, but the Marines who go through MALS consistently outcompete their peers at the Sergeant board. The second decision is whether to pursue the Naval Aviation Supply career path toward a Limited Duty Officer (LDO) package — the E4/E5 window is when you need to be building the academic record if that's the goal.

At a VMFA squadron, the pace is highest and the technical complexity is concentrated on a smaller, high-value aircraft fleet — every NMCS event is high-visibility. At an HMH or VMM (tiltrotor) squadron, the rotary-wing parts logistics involve heavier use of contractor logistics support (CLS) and depot relationships that add coordination complexity beyond standard MILSTRIP. At MALS, you're the supply authority for multiple subordinate squadrons and the work is more systems-management than transactional — discrepancies at MALS affect multiple aircraft across the wing. MAG headquarters supply billets are administrative and career-building rather than operationally intensive.

An outstanding E4 in 6672 knows every aircraft tail number's current supply status without looking it up — they have internalized the AWP report. They proactively identify AVCAL deficiencies before the quarterly review, draft the justification package for allowance changes, and hand it to the supply chief ready to sign. They are the Marines the Aircraft Maintenance Officer calls by name when there's a supply problem, not because they made the problem but because they fix them.

Sergeant means you are managing the entire supply section under the supervision of a Staff Sergeant — not just your functional area. You will write counseling statements, manage scheduling, and be the technical authority the junior Marines call when the system throws an error code that isn't in any manual. The expectation is that you know not just what to do but why, and that you can brief the Supply Officer on readiness impacts without notes.
