OK, I did miss that to be honest. On the other hand. I really do not think the captain would be that stupid. Not to mention.... they would still have some level of anti-boarding action stuff. Some of the crew and command staff would be armed. I would bet all my money that there are some heavy turret emplacements at key points inside. Like... the bridge, reactor etc. Just because it says it's a weak ass target for boarding doesn't mean the moment a soldier comes on board he wins.

Oh and how many of our characters are familiar with elder engineering? Who knows where the bridge would be located? So again I don't see a win here. Slightly less insane but still.
