The 2 letters stand for a particular rectangular area on the map/globe. Mostly in alphabetical order, but not completely sequential around the globe. The coverage of sea and coastline was guiding.
Then each number digit resemble a subdivision of the larger rectangle. Divide it up like a 3x3 telephone numberpad. 1 at the top-left, 9 at the bottom right. The number of the digit in the grid-reference determines which 'button' to consider. Then further sub-divide the button by 3x3. And take the next number digit in the grid-reference to narrow down to smaller area. And so on, and so on, until it is pinpointed sufficiently. There should not ever be a 0 in that gridreference. But you'll eventually come a cross a gridreference in the game, either given by SH3 Commander as a patrol assignment, or by some radiomessage, of something like "BF10" or "AM10". You can ignore that. Or any patrol grid assignment really. Nobody will blame you if you ignore such orders. |
