As for Kress' statement, and as a more general statement as well, I agree about the Unioner non-combat ship. Rheinland unlawfuls seem to have more legitimacy than other unlawfuls - If all of lawful Rheinland disappeared, you'd still have a government, miners, shipbuilders and farmers all ready to get to work. They're all friends and they all want a better Rheinland or whatever, so I can see them using more non-combat stuff than their equivalents in the other houses to try and legimitise their claims to be fighting for the side of good.
Not that that has much to do with me sticking up a train in my behemoth, though. Ho ho.
