A grid reference you can say out loud.
Also known as: Military Grid Reference System, MGRS coordinate
The military grid reference giving a position as a zone, a square identifier and a pair of digit strings.
Gives a position by zone, hundred-kilometre square and a digit pair whose length sets the precision.

Precision is chosen by how many digits are given, so the same scheme reports to a kilometre or to a metre with no change of notation — the reference states its own accuracy by its length.

Built to be spoken: the letter square removes most of the leading digits a full grid reference would need, which is what makes it usable over a radio under pressure.

A zone designator, a two-letter hundred-kilometre square identifier, and an even number of digits split between easting and northing.
