Aviation Supply Specialist

The Sergeant's morning starts before the junior Marines arrive — review the AWP report, pull the CASREP list, and identify anything that changed overnight so you're not walking into the maintenance brief blind. Run the morning section standup: outstanding NMCS requisitions, DIFM follow-up assignments, receipt processing priorities. Spend mid-morning on system work — requisition register audit, AVCAL review, FEDLOG lookups for parts the maintenance shops have been requesting. Afternoon is the operational liaison work: calls to the MALS SMD on backorders, meetings with the AMO's supply representative, and the weekly readiness data call if it falls that day. Late afternoon is training and counseling — reviewing junior Marine work products, identifying errors before they become audit findings, writing counseling statements.

Monday: section stand-up, assign the week's follow-up responsibilities, review the prior week's requisition log for any unresolved discrepancies. Tuesday: DIFM accountability review — every item over 10 days since turn-in gets a personal follow-up contact, documented. Wednesday: prepare the Thursday aircraft readiness brief inputs — tail-number-level AWP data, root cause on top grounded aircraft. Thursday: attend or support the Aircraft Maintenance Officer's weekly readiness brief. Friday: AVCAL spot-check against current on-hand quantities, initiate any needed replenishment requisitions. Monthly: full section inventory per MCO 4400.16, financial reconciliation of obligation authority, counseling all assigned Marines.

Section leadership and training program ownership — you must build and run a formal on-the-job training program for E1-E4 Marines that is documented, tracked, and produces competent supply technicians, not just process-followers. AVCAL management at the Sergeant level means owning the quarterly review, preparing the allowance change requests, and briefing the supply chain impact analysis to the Supply Officer with numbers that hold up under scrutiny. Demand analysis for replenishment decisions requires you to read consumption patterns, identify aviation cycle-driven demand spikes, and make defensible quantity recommendations that don't over-burden the unit's financial obligation authority. CASREPcoordination between the squadron and MALS means you are the functional liaison — you understand the maintenance trigger, the supply action required, and the escalation path if the MALS cannot source the part. Inventory control and survey procedures are an E5 competency — you run the physical inventory, identify discrepancies, determine cause, and prepare the survey package if required.

NAVSUP P-485 Chapters 4 and 6 (Requisitioning and Receipt Processing) are your technical authority for training your junior Marines — you need to know every table, every exception, every error recovery procedure. MCO P4400.150 is still the priority designator authority, but at E5 you're using it to audit your section's work, not your own. COMNAVAIRFORINST 4790.2 Maintenance Program is now a leadership reference — understanding what maintenance is trying to accomplish tells you which supply failures are intolerable and which are manageable. The Wing Readiness Manual (varies by Wing) governs the aircraft readiness reporting that your AWP data feeds — understanding how your supply status affects the readiness brief makes you a better operator. MCO 4400.16 inventory management procedures govern your physical inventory process — know the required frequencies, the documentation, and the reporting chain.

At E5, the standard is a section that passes unannounced spot-checks without your intervention — meaning your training program actually works. Zero CASREP supply requirements without daily documented follow-up. AVCAL allowances reconciled quarterly with written justification for any deviation. Every survey action completed within 30 days of discrepancy identification. No NMCS requisition older than five days without an escalation memo to the Supply Officer. Junior Marine counseling documented at least monthly with specific performance indicators, not generic statements.

Failing to recognize a SHOREREC/ERP system duplicate-posting situation where two operators entered the same receipt independently — the inventory inflates, the obligated funds drop incorrectly, and the discrepancy doesn't surface until the annual financial audit. Not managing the FEDLOG cross-reference database updates — when NSN changes are published and your AVCAL still lists the old NSN, you're issuing material against a defunct record. Incorrect application of the Cooperative Logistics Program (CLP) procedures when a part is sourced through a foreign military sales agreement — the documentation chain differs and an error can create an international accounting discrepancy. Misunderstanding when a DIFM asset requires a DD-1348-1A survey versus when it can be processed as a routine turn-in — wrong call creates either unnecessary property loss or an unauthorized retrograde.

The Sergeant Career Designation Board window is the most consequential decision point in the 6672 career — designating into the supply management career field with a MALS-tracked service record positions you for Staff Sergeant and potentially LDO selection, while staying in the operational squadron rotation is more variable. The second decision is whether to pursue a formal supply management education (Defense Acquisition University, Naval Postgraduate School enrollment as a graduate, or an accredited degree in logistics) — the Marines who build credentials during the E5 window have materially better options at the twenty-year mark and beyond.

Sergeant billets at a VMFA squadron are operationally intense — the supply section is small, the aircraft value is highest, and the NCO is often the most knowledgeable supply person in the building after the officer. At HMH or VMM squadrons, the parts ecosystem involves more contractor logistics support coordination and the AVCAL structure is different enough that a Sergeant from a fixed-wing background needs a genuine learning period. At a MALS IMA (Intermediate Maintenance Activity) supply billet, the Sergeant is managing supply support for multiple squadrons across the wing — the accountability scope is much larger and the technical complexity of demand aggregation is significantly higher. MAG or Wing staff billets are career-broadening and visibility-raising but remove you from the operational depth that promotion boards reward.

An outstanding Sergeant in 6672 knows the AVCAL history for their aircraft type going back two years without pulling a report — they have internalized the consumption patterns. They present the weekly supply status brief to the Aircraft Maintenance Officer with tail-number-level detail, explain the supply chain reason for each delay, and have an action plan for the top three grounded aircraft before they are asked. Their junior Marines make fewer errors each month, not the same errors repeatedly, because the training program is actually working.

Staff Sergeant in 6672 is a section chief or division SNCO billet — you are responsible for the entire supply section's performance, not just your functional area. You will be writing the budget inputs, the manpower justifications, the inspector general response packages, and the training program documentation. The expectation is that you can represent the supply department to the CO during an IG inspection without the Supply Officer in the room. If you cannot brief supply readiness metrics at that level, you are not ready for Staff Sergeant.
