I assume the game is meant to be played with the knowledge of some supplementary course and material.

I assume that it is intended to facilitate the Army's Land Navigation (LANDNAV) training for Soldiers. MGRS is the standard format for all US Army maps.
That's interesting, if true.
In my time in the Infantry we spent a significant amount of time working on honing landnav skills, both theory, and practice.
*Edit* Also, there is already a manual for everything you do in the military.
They seem to be doing great work on that front. I was favorably impressed by the documentation attached to the tools in the game.
