How do they work out the last 2 digits?:hmm:
For instance from the uboat forum:
Each smaller grid within the main quadrants (like the "56" inside AE) was then further broken down into smaller elements to enable the Kriegsmarine to use designations like
AE 5619 (shaded grid).
Reykjavík, in the map above, is located in grid
AE 4874.
The entire world was mapped like that, including areas that never saw any Kriegsmarine operations.
AE 4874.
Well yeah i know where the AE48 is coming from but where they get the 74?
