Balka Damage

By panzerjaeger, in Tide of Iron

I've got two questions about vehicles in Balka.

1. If a vehicle during a single advance action passes through a Balka (i.e. enters it and exits it) does it check for damage once or twice?

2. The rules say that a vehicle damaged by a Balka is lightly damaged, so if a vehicle were already lightly damaged is it immune to balka damage, or do we read between the lines and assume it takes a hit of damage and becomes heavily damaged?

Thanks for you help.

My opinion:

1 - Roll twice

2 - Heavily damaged

It would have been nice if the rules had covered such obvious issues explicitly.

I get the strong impression that FotB was released before it was ready.
