You Could Look It Up: DoD Dictionary Updated

The newly updated edition of the Department of Defense Dictionary of Military and Associated Terms includes a new entry for “Improvised Nuclear Device.”

It is defined as “A device incorporating fissile materials designed or constructed outside of an official government agency that has, appears to have, or is claimed to be a nuclear weapon that is no longer in the control of a competent authority or custodian or has been modified from its designated firing sequence.”

The 400-page DoD Dictionary, now updated through 15 October 2016, is a useful reference for interpreting specialized military terminology and for decoding current acronyms, which are listed in a 120-page Appendix. But it is also a reflection of current DoD concerns and priorities.

Another new entry in the latest edition is for “resilience,” which here means “The ability of an architecture to support the functions necessary for mission success with higher probability, shorter periods of reduced capability, and across a wider range of scenarios, conditions, and threats, in spite of hostile action or adverse conditions.”

The update replaces prior editions which were designated Joint Publication 1-02. For unknown reasons, the JP 1-02 document format has been abandoned in the new edition, which is simply entitled DOD Dictionary of Military and Associated Terms.
