I dont know if this has been suggested or not, but incase it hasn't i figured i'd throw it out there.
A grid system for the map. on the X and Y axis of the map there is already room for simple A,B,C etc.. and 1,2,3..etc.
Having to say "SS @ 56/71" or "CV @ 112/67", gets some people looking a little too much.
Why not just have something like? CV A4 or BB6 F6? It may not be precise as the current method to call out targets,
but it would make it easier in general to call out a target, or request support of some sort (Air Cover, Smoke Bombs)
Just a Suggestion. (:
