NTRP 1-02 supplements Joint Publication 1-02 (JP 1-02), Department of Defense Dictionary of Military and Associated Terms. The terminology established by NTRP 1-02 shall be used without alteration unless a distinctly different connotation is intended. For guidance in preparing glossaries and lists of acronyms and abbreviations for NWL publications, consult NTTP 1-01, The Navy Warfare Library. Terminology included in NTRP 1-02 is collected from the main text of promulgated Navy publications and widely-used allied publications. Terms that are adequately defined by or that have definitions that can be derived from a standard collegiate dictionary are not included. Terms defined in JP 1-02 are not included in NTRP 1-02 unless Navy usage has a markedly different context or meaning. Abbreviations and acronyms in NTRP 1-02 reflect standard meanings for those used most commonly in NWL publications. As a general rule, abbreviations defined in standard collegiate dictionaries are not included. Entries do not include prowords, code words, or brevity words. As changes are approved for NTRP 1-02, they are added to the online database, making the online version more up-to- date than any printed edition. The authoritative version of NTRP 1-02 is the online database in the Navy Warfare Library, accessible on the Navy Doctrine Library System website (https://ndls.nwdc.navy.mil/assets/Terminology.aspx). The printable file that is created periodically and added to the website is a database report that facilitates terminology work offline. Both the online and printable versions reflect the idiosyncrasies of databases, including anomalies in alphanumeric sorting. 1-1 APR 2011 NTRP 1-02 INTENTIONALLY BLANK APR 2011 1-2 NTRP 1-02 CHAPTER 2 TERMS AND DEFINITIONS 360-degree security.
