Grid

To aid navigation, each Continental and Cavern map is divided into a grid of squares.

Each grid location is referenced by "letter-number", with letters starting at A and going from left to right, with numbers starting with 1 going from top to bottom. Therefore, the top left corner is A1.

The actual area of each square varies by map.

Additionally, the grid coordinates for the square you are currently in is displayed in your Proximity Map, and the locations of squad and platoon members is displayed under their name on the HUD.
