Bridge builders in tutorial #3

[FroBodine]

Stupid question - how do you use the bridgebuilder unit in the 3rd tutorial mission?

I moved them to the river, but nothing happens, and I could not see any option to build the bridge?

What am I doing wrong?

Bridge engineer unit standing on a river acts as a bridge for other units. So, just place it on the river, and other units will be able to cross at this point.

That is exactly what I did. I wonder if enemy units adjacent to the bridge engineer were not allowing my units to cross. I was trying to move units onto the bridge unit and attack from there, but it did not work.

I will try the mission again and cross the bridge away from enemy units and see how it goes.
