I guess tactical doctrine isn't that bad as it puts one of the mechanics of the game to good use.

I feel that if you succeed to put your engineers into a position to use this ability, you should reward them with a powerful outcome.

Since, as far as I know, only the Germans used remote demolition and since they are flexible doctrine in every theatre except Norway '39 I guess it make no real difference.

I've certainly read accounts of the larger Borgward IV vehicles being used against several different troop targets in a single engagement, I can't believe the more expendable Goliaths would be less readily used in the same way.

Like so many supposed "wunderwaffen" the remote demolition weapons were unreliable and expensive but very effective in ideal situations.
