A D5 Cat is a 70 yr old design and isn’t particularly impressive. The ‘D’ designation has no dash either.
Multiple meanings.... drive D5 old-school worldview to snowball deep state down the hill, into the Abyss.
I also recall Donald Trump Jr talking about a D5 cat during the campaign, perhaps it was at the Convention. Odd. I think he was talking about knowing the people who work for you and what they do.
