In a scenario of France, tanks and vehicles are allowed to move over a wreck, and doing it, the wreck is removed.

On image 1 the infantry can remove the wreck.


But it's not necessary because moving the tank on it, it'll remove the wreck.


Another exemple

In a recent MP scenario: MPARNHEM*capture_the_crossing_mp), the target was the bridge, near the end of the scenario, the bridge was occupied by an enemy tank, I killed it, so a wreck stay here, but I was unable to remove it, and so, either infantry or vehicles can go onto the bridge again to retake the flag.
Is there a way to understand how the wreck are controlled in each scenarios?, is there a script where is defined?
In that case, the remove icon wreck was dimmed on all adjacent units with enought AP's to remove the wreck (4 AP's).

Vehciles can move through wrecks but it uses a lot of additional movement points. Moving through destroys them.
