This regulation establishes uniform source maintenance and recoverability codes for all Department of Defense Services/participating agencies and prescribes policy and interprets guidelines for the initial assignment, changes to and application of these codes. This publication reflects the changes in terminology required by the MILPRF-49506, Performance Specification, Logistics Management Information, which replaces MIL-STD-1388-2, DOD Requirements for a Logistics Support Analysis Record. Uniform SMR codes will be used by all DOD Services/PAs. Subject to the Service options contained herein, each Service/PA will ensure that the coding structure and application of these codes are used by their logistics management systems in order to provide uniformity and a means of inter-Service/agency communication of information for multi-Service/agency equipments. All Services/PAs are not required to use every SMR code contained herein. However, only codes contained herein will be used when SMR codes are assigned. A table of approved SMR codes for all Services/PAs is located at appendix B, table B-1.
