The system contained in the U.S. Department of Defense Handbook of Military Symbols (MIL-STD-2525C) is designed to eliminate conflicts within various symbol sets and to establish a core set of common symbology under one Department of Defense standard. This handbook provides sets of C2 symbols, a coding scheme for symbol automation and information transfer, and technical details to support systems, which makes it the best tool to learn the complete symbology of warfighting. Revisions not seen in the previous standard include sections on emergency management symbols and using symbols in pseudo-three-dimensional displays. It also provides a thorough list of definitions and acronyms, along with tables and figures displaying thousands of symbol variants.
