The spotting from the squad-deployment-screen is to powerfull. You dont even need your team to mark it. I would suggest to hide enemy movement completely on this screen. And I would suggest in general to mark tanks not exactly where they are, but show a bigger area where they are. Mark it with a moving red circle.
In tunesia its the worst, since there is no cover for them. I can spot almoast every tank of the enemy from the squad-deployment-screen and nuke it away with 1000kg bombs. No skill needed.
If you want some sort of reconnaissance, then add a ability for radio operators to ask for a reconnaissance plane that makes enemy movement visible on the map or squad-deployment-screen for certain time.
