Destroying terrain

[Scorpio_Rocks]

Any Class #37 "Engineer vehicle" is capable of flattening a building, in game, safely (ie without getting stuck).
It may also be true of all Mine Plough / mine clearing tank class too, unsure.

As for the blowing holes in terrain, hedgerows, etc - I believe you are mistaken, the description Hedgerow hole means that there is a hedgerow AND a hole (in the ground) in the hex NOT that there is a hole in the hedgerow. Check after a Heavy artillery barrage many terrain types can also have "holes" - shellholes. Slightly advantageous as cover for stationary inf and slightly harder (higher cost) to move through for all units. I do not believe it is possible to "destroy" terrain - other than bridges and changing buildings to rubble.
