Hey Moopy, just
FYI you might want to get the post moved to
YMDC, as this is the Swap Shop, common mistake
As far as your question goes, I would say the first option because I would take a guess that whole models have to be removed first. Also, special weapon squads are only allowed to be equipped with 1 Demo charge, so unless you have 2
SWS really close and they're both wiped out by the D-charge, that would be some karma.
