Synopsis as published on the index

This Order clarifies materiel readiness reporting procedures, and provides logistics information reporting guidance in support of capabilities based assessments and operational readiness reporting through Department of Defense systems such as the Defense Readiness Reporting System-Marine Corps (DRRS-MC). Logistics information systems and force structure requirements systems contain information relevant to resource management, equipment condition/equipment availability and requirements. This information alone does not provide an assessment of capabilities. This policy includes amplifying guidance for reporting the temporary reassignment of readiness reportable assets in support of task organized units as defined in paragraph 4.a .2.a .3. b. This Order provides the framework to present objective, relevant and accurate logistics information for Marine Corps units and selected commands. Additionally, this Order outlines the process for retrieval, integration and processing of essential and authoritative data through various systems to: (1) Reflect the current operational condition of reportable ground equipment and supply inventories by reporting activities. Readiness Reportable ground equipment is identified and published annually in the Marine Corps Bulletin reference (j) series. (2) Present an overview of the effectiveness of maintenance programs and supply chain management procedures in support of ground equipment reporting. (3) Provide data that reflects the measure of an organization's equipment inventory compared to its mission requirements. The "S" rating (equipment availability) indicates the ability of supply chain to support equipment requirements. (4) Provide data that reflects the measure of an organization's operational equipment availability. The "R" rating (equipment condition) indicates the condition of the equipment an organization has on-hand, without regard to that organization's equipment requirements. Represented as a percentage, the R-rating is the equipment on-hand minus the equipment deadline divided by the equipment on-hand. Specific guidance on the formula for calculating the Supply/Equipment On-Hand Readiness ('S '), Maintenance/Equipment Condition Readiness ('R'), and Materiel Readiness ('MR') ratings can be found in enclosure (1). (5) Provide an overall assessment of a unit's MR rating in order to measure the overall equipment readiness at various levels (i.e., Functional Area (FA)/equipment type/organization, etc.) within the Marine Corps as defined by enclosures (1) and (2). Numerically, the MR of a unit is represented as equipment on-hand minus the quantity of equipment deadlined divided by the Table of Equipment (T/E) quantity. (See enclosure (1)).
