River crossing scenarios?

[Huib Versloot]

- What is the fundamental difference between a heavy full hex bridge or a heavy full hex pontoon bridge?

In game, none. Pontoon bridge is made in the scn file.

- How heavy must a pontoon bridge be to allow for medium tanks, is there a way to create them so that heavy tanks cannot cross (IS-2s, ISU-152s), but the said medium tanks e.g. T-34 SU-76 let alone T-70 can do so?

Dunno, never tested that. Should not be too difficult in a simple test setup.

- Can either one (full hex bridge, remember) be damaged , or are they basically the same, just visually different?

Both can be damaged, but NOT during the game.

For historical reasons I will need both real bridges and pontoon bridges, but is there a difference how they should be used during the scenario?

No difference except that a pontoon bridge may be not directly connected to a road.
