Hide and Seek...

[Grit]

If units can hide in trees to heal can they also hide to say flank or conduct covert ops that would be sweet

[CivX]

Or ambush(auto attack) any units who try to enter the forest or jungles?

Would an ambush in a marsh have a greater damaging effect?

If so would an ambush only happen on another human players turn? and if so, would he not just reload the map and decide not to actually step foot on that tile?

If you have played Advance Wars you will know what I mean. In it under fog of war conditions (of course in this it would not exist to long) forests hide units until they are discovered by an ajasant enemy unit. The forest would be the only one revealed any conecting forest (jungle, etc.) could still conceal a unit.

And yes decidedly we are humans we cheat so unless you want to send someone with every game to make sure you don't reload everytime you get in a sticky situation it will happen.

This was implemented in Sid Meier's "Pirates!" which is a respectable game. When besieging a city in that game, one could hide in trees, and flank opponents from the sides and back.
