Bonus when assaulting with engineers ?

[Mr Grumpy]

Yes as far as i know engineers do not add any modifier to an assault on a fortified hex, the only way some engineers effect an assault is with their higher than normal assault values, the best example of this are the Sturm glider engineers in F40 who assault Fort Eben Emael with a value of 50, however if you check the assault values of engineers in other titles they are often higher than normal infantry. ;)

It is also worth pointing out that mine clearing and bridging engineers can have very low assault values for obvious reasons.
