You mean the BAT was not able to remove obstacles? even the BAT-M with the mobile crane? I read from your site (lousy Babelfish translation) that, in addition to tracklaying, it can be used for "clearing passages through obstructions" and "load-lifting". If for game purposes a civilian bulldozer can be considered to move dragon teeth out of the way, then why not a BAT?
Precision: a
dragon tooth is not a mine, but a solid concrete obstacle designed to stop tanks (you see well how they look in the game). You just need a tracklaying blade and enough engine power to move them, or a crane to lift them away.
(Yeah, I know, wikipedia source, now don't tell me there's much controversy on that issue!)
