I have played many team games. One method to get around the labels is take a screen shot and drop it into your favorite editor. Draw a few lines and arrows and send to your team mate(s).
As a commander, limit your remarks to goals for the game day and let your team figure out how to do it.
Usually villages, cities or towns and a compass direction can convey a point.
In some team games, we created our own names for locations as the battle developed. Rats nest, "the slot", killing field, and that big #$%@ hole, come to mind...
In the end you may feel like Napoleon at Waterloo wondering what Ney and Grouchy are doing. That is part of the fun being in a team game.
