Yeah I borrowed a bit from a Semovente and a StuG because I don't want them to look too much like any countries tanks from OTL. The Armadillo is an assault vehicle and meant to attack fortified positions but it will evolve into a tank destroyer later.I spy an Italian Semovente influence it there! Well it makes sense since you're using an Italian made turret for the main tanks of the Confederates too. Want to carry over that kind of style to it I suppose. I kinda rely like the look of this one too! Its squat, flat, but looks foreign enough from the german inspired designs to make one say "hey yeah, that's a confederate barrel". Plus the Italian designs aren't as well known too. would have figured there would be a longer gun, but that may be for a late design thing. This thing looks like it can take on US tanks.
Designation "Armadillo" is cool too. You got a name for the Confederate main tank you made? I think the Confederate naming convention leans toward animals in general.
(Side note: Italy was actually neutral in both wars in the novels, to the annoyance of both the Central Powers and Entente. It stayed especially neutral in the Second Great War too, with Benito Mussolini not coming to power. So I say using Italian designs is a plus, since Italy's tank development in TL-191 would be especially behind.)
I like using animal names and I think it works for the CSA, I named the six wheeled armor car the Badger the SPG the Armadillo but I didn't name the medium tank yet, if you have an idea for a name go ahead and post it.
I was thinking of maybe using canine names for the tanks, the way the Germans used cat names for their tanks.
So maybe wolf or Coyote?
