Blowing up bridges when enemy troops are crossing

[AlienXXX]

Hello,

I have blown up a few bridges in SPWW2 and MBT with artillery.
I don't think I ever caught an enemy vehicle crossing, though.

When this happens do I get a message ?
Does the artillery unit that fired the shell get the kill point in the same way as if it had destryed the vehicle with a direct shot?

Thanks
