Materiel Management Block 1 Unit 3 Questions & Answers 2026/2027 | 98 Questions | LRS, AFMC, DLA, NWRM, COMSEC & Physical Security | AFSC 2S0X1

This comprehensive Materiel Management Block 1 Unit 3 2026/2027 study guide contains 98 questions and answers across 25 pages and is presented as an expert-verified resource designed to help learners prepare for the assessment. It provides detailed coverage of Logistics Readiness Squadron (LRS) organization, Materiel Management Flight functions, Decentralized Materiel Support, Air Force Materiel Command, Air Force Sustainment Center, Air Logistics Complexes, Defense Logistics Agency, General Services Administration, Centralized Repair Facilities, supply classes, Nuclear Weapons-Related Materiel, classified and sensitive assets, COMSEC/CCI, Small Arms and Light Weapons, inventory control and physical security. The opening section provides an in-depth review of the Logistics Readiness Squadron and its organizational structure. The material identifies four LRS flights—Materiel Management, Deployment and Distribution, Fuels, and Vehicle Management—and discusses the responsibilities of the LRS Commander, Operations Officer and Logistics Manager. Materiel Management is presented as the primary liaison between customers and the Air Force Materiel Command supply chain, with responsibilities including storing, inspecting, inventorying, issuing and returning materiel, managing the repair cycle and providing customer support. Students receive detailed coverage of the Materiel Management Flight (LGRM) and its subordinate functions. The Asset Management Section includes the Aircraft Parts Store, Central Storage, HAZMART, Individual Equipment Element, Individual Protective Equipment and Flight Service Center. The guide explains the responsibilities of Equipment Accountability, Customer Support Liaison, Inspection and Flight Service Center personnel, including equipment authorization, repair-cycle management, warehouse functions, hazardous-material control, mobility equipment and customer logistics support. A substantial section examines Decentralized Materiel Support (DMS) and maintenance logistics. Students review DMS responsibilities for managing supply transactions, repair-cycle assets and requisitions, resolving supply-support problems, monitoring backorders and supporting maintenance activities. The material also discusses Not Repairable This Station (NRTS) lists, Supply Assistance Requests and Government Purchase Card support, connecting Materiel Management procedures directly with aircraft maintenance and mission readiness. The guide then explores Air Force Materiel Command (AFMC) and its five centers for science and technology, life-cycle management, test and evaluation, sustainment and nuclear support. It reviews the missions of the Air Force Sustainment Center (AFSC) and operations at Tinker AFB, Hill AFB and Robins AFB. Students also study the Warner Robins, Oklahoma City and Ogden Air Logistics Complexes, including the weapon systems and maintenance capabilities associated with each location in the course material. Source of Supply concepts and the 635th and 735th Supply Chain Operations Groups are also addressed. Another major examination area covers the Defense Logistics Agency (DLA), General Services Administration (GSA) and Centralized Repair Facility (CRF). The document reviews DLA logistics support, supply chains, distribution centers, supported weapon systems and organizational values. GSA content focuses on commercial products, tools, equipment, vehicles and commodity support. CRF questions examine regionalized intermediate-level maintenance and potential benefits such as reduced airlift requirements, reduced forward-location support requirements, asset pooling and opportunities for logistics improvements. Supply management is reinforced through Class II, Class VII and Class IX. Students review Class II organizational clothing, equipment and consumable supplies; Class VII major end items, described in the source as the backbone of the Air Force; and Class IX repair parts used to maintain mission-capable status. The document also introduces the Expendability, Recoverability, Reparability, Cost Designator (ERRCD) in connection with Class IX items. The later sections provide extensive preparation on Nuclear Weapons-Related Materiel (NWRM) under the guidance identified in the document as AFI 20-110. Topics include accountability, discrepancy reporting, inventories, marking and packaging, IUID, AF Form 4387, DD Form 1500-series condition tags, storage, issue authorization and personnel training. Students also review procedures for classified materiel, including Top Secret, Secret and Confidential classifications, receipt authorization, document control, semiannual revalidation, inventory requirements and destruction records. The final portion concentrates on COMSEC, Controlled Cryptographic Items, Small Arms and Light Weapons and physical security. Students study Airborne, Deployable and Fixed COMSEC/CCI categories, serial-number control, authorized access and secure communications equipment. The guide also covers SA/LW inventories, equipment-custodian responsibilities, controlled materiel transactions, GSA-approved security containers, combination locks, need-to-know access, controlled entry points, visitor logs, identification procedures and warehouse visitor controls. These topics make Unit 3 particularly valuable for reviewing accountability and security responsibilities alongside traditional supply-chain operations. Relevant students: This resource is particularly relevant to AFSC 2S0X1 Materiel Management students, U.S. Air Force Materiel Management Apprentice trainees, Airmen preparing for Block 1 Unit 3 assessments, Logistics Readiness Squadron personnel, Materiel Management Flight personnel, supply and warehouse trainees, maintenance-support personnel, DoD logistics learners, equipment custodians and students reviewing controlled materiel, NWRM, COMSEC and physical-security procedures. The document is structured around U.S. Air Force logistics and Materiel Management training rather than a university course, so U.S. Air Force is the appropriate institution for the title.
