Well after posting AAP-6 for Map Symbols, I figured I might as well post terms and definitions as well. Enjoy!
Now DND doesn't have a published document per say, we have a Jont Terminology Database on the DIN, but the nice folks at Army.ca have prepared a useful guide.

The fun one is US JP-01-2
Department of Defense Dictionary of Military and Associated Terms. This is where you'll find your shit hot terms like "kill box" and "beam rider"

UK MoD's version Joint Doctrine Pub 0-01.1, very similar to NATO but noted where different.

Again, NATO AAP-6
NATO GLOSSARY OF TERMS AND DEFINITIONS

* Note in a completely self-serving aside, on the front page they list ADM (HR-Mil), which has been superceded by Chief of Military Personnel or MILPERSCOM depending on context.
