This document was prepared by the SAE AS-1B1 IMM Task Group to explain and document background information and design decisions made during the development of AS5726. This handbook is published separately to preserve information that is not required or provided in the AS5726 but may be important to system designers to ensure interoperability between the Micro Munition Host and Micro Munition. As a handbook, it cannot be invoked as a requirement in a contract.
