Hidden units. What do you say about this?

[Outlaw Josey Wales]

No zoc leaves the possibility of bypassing them, but also leaves them in your rear. Most scenarios don't really leave enough time and troops to move through every hex. I think if you find them, take them out unless leaving them in your rear doesn't pose any threat to what you are doing or have to do. The problem I have is it seems the Russian communications was nothing to brag about at best, but seem flawless in the game. We've all read about Russian tank comms, and it seems the infantry comms weren't much better if in fact they were. Somebody with much more knowledge of that would be better to talk about it.
