River crossing battle tactics

[Imp]

So "Imp's firewall" is a limited usage tactic, but possibly useful in the right circumstances.

I have found it very effective with most terrain TI units tend to be back from the river bank so can deny them sight or change the anty by making them move. Difficult to guess LOS with fire & smoke so set yours up covering where he might move for & start piling everyone else in the water while hitting the far bank with conventional arty.
If you are lucky can hit infantry fairly near to the bank & deny LOS to places further back with the same volley, couple of strikes & your window has opened.
If you have them now is a good time to send in the planes as his armour might be on the move so easier to detect plus may give you some idea of which way to break out once you are over.
