FitS Scenario 8 - Bridge questions

[J6A]

I have a few questions about this scenario and I'd appreciate input.

1.  The Bridge Panic special rule refers to "broken units."  This term isn't defined in PG.  Is that DIS and DEM units, or just DIS?

2.  Do broken units which are removed from the bridge count as eliminated for victory purposes?

3.  The victory conditions give the Soviets 2 for each unit which crosses the bridge.  Is this only awarded for units that use the bridge, or is it received for units that swim the river?
