Maps with big rivers + bridges + engeeniring unit

That is point in which CoW is not that realistic.

In II World War and even now, in XXI century in real life war in Syria, rivers matter a lot!

Crossing them, without bridges is very hard and slow. And bombing bridges or blowing it up was a part of military strategies since ever.

But the maps does not shows it.

It would be great to get maps with big rivers shown the way, they are not possible to cross without bridges, as in real life is.

So normally every province with such river, would have bridge. I guess it could be building with 3 levels for example. 3rd level is a lot of bridges and strong ones, 2 is medium, and 1 is not many smaller bridges - as symbol of real life. Some provinces like in Siberia might have rivers but no bridges initially, as in real life

So overtaking province or bombing it would damage bridges.

Bridges could be rebuild or blown up by engeenirs unit. Engineers unit would be one of armor units

Building bridges would take time. Blowing up would take time too, as explosives need to be put on bridge by engineers.

It would be good that You would be able to bomb Your own bridge too, as in real life it's possible (by bombers or artillery, naval units).

Engineers would be slow as in real life, to travel. On different levels they would took different time to set up/blow up a bridge.

This would be game changer. I guess not everybody would like to play game with bridges so it could be as optional version of maps, with engineers and bridges.
