In my experience playing for example, I've seen a grid system being used instead. Now calling out for example, "__ KB__" works well, to an extent. But it wouldn't be as precise. What about rougher terrain, etc? You get the idea.
Something else that could possibly work in conjunction, or perhaps alone would be to have a highly detailed grid on the map in-game. Basically smaller squares within the square.
Again, the Radio Idea is just a thought. For all I know it's impossible to VOIP over different squads. I would think not.
This could potentially clear SAY chatter a bit more on a more "serious business" server. Presumably all of them. Some being more leaniant than others, in terms of rules. That's aside the point. The point I'm making here is, I believe either of the two things I suggested (or both), would add further to the realistic immersion players find themselves in when they play Project Reality.
