TThe "Hiden Minefield" strategy card from the Desert Tactics deck in DAYS OF THE FOX provides for placement anywhere except in any hex containing an enemy unit. Is it therefore correct to understand that a minefield can otherwise be placed in ANY hex regardless of terrain, including bridges and buildings? If not not, then which terrain type(s) would prohibit the placement of a minefield in it? (Since it's not spelled out better anywhere in the rules, in the FAQs, or on the card itself, I'm assuming one can place the minefield anywhere.)

This is how I have always played it, the rule book dose not list any terrain types it can not be used in. In fall of tobruk my friend played this card on me and put it on one of the bridges which then left only one safe route open (if you could call it that, since alot of his firepower was directed over there). As for the building I guess it could represent the buildings being booby traped.
