[SG] Buildings & suppression

I was reading the SG2 book last night, mainly the beginning sections that I
usually just skip because 'the interesting rules are all further back in the
book' when I came across something quite interesting...

How exactly does suppression affect buildings? On, I think, page 18, under
'Suppression to Vehicles & Buildings' the rules seem to say that the only
affect of suppressing a building is to make it impossible for a unit to exit
the suppressed side of the building, or the two adjacent sides. In common with
vehicles, it seems to suggest that units in suppressed buildings can still
fire & move, just not out that suppressed side. Is this the case? (Jon?)

If so, this makes buildings & urban combat a LOT more dangerous, as if it
wasn't dangerous enough already.

If this is true, I'd like to suggest the following: Minor sucesses on units in
buildings only suppress that side of the structure; a Major success puts the
Suppression directly on the target squad as normal, along with the attendant
casualties as usual. It makes squads holed up in
buildings more dangerous, but I can sort of see the logic of it -
there's a LOT more cover in a solid building than in nearly anything else; so
it's a sort of cover bonus, above the Hard Cover shifts the squad would
usually get.

Comments? An [OFFICIAL] sort of ruling/interpretation, Jon?
