4h Edition Terrain Modification Rule?

[Blackcloud6]

Thanks, and that is how the Tank Dinosaur and I played it a few weeks back.  What I am seeking though, is the rule that tells us to do it this way.  There does not seem to be any in the PG 4th Editon RB, and I word searched extensively and there is nothing in the AAaD Special Rules.   I believe it was Afrika Korps that had the special rule to place the terrain change marker on the hill and the hill of that color changed to whatever marker showed it to be.  AAaD should have a similar rule if there isn't one in the main RB, right?
