Bonus when assaulting with engineers ?

> ALL ENG can clear mines at a rate of one facter per turn regardless of their quality.

Engineers must be designated as mine clearing types to clear mines. Some bridging engineers don't have this capability, they can only build bridges. So check carefully what type of engineers you have. Bridging engineers are useless for clearing mines and will even take losses if they step into a minefield.
