Tanks crush tank corpses. Not AT gun corpses.
If Soviet AT guns can be recrewed by other factions but not
soviets, then that's a serious balance issue :p I can easily
imagine US/Brits taking 'em from soviets (since they're cheaper
but just as good) kinda. Will they keep ambush/threadbreak
once stolen?
AT gun corpses should just vanish when the crew dies,
to prevent massive piling up :p
