We just got the same copy-paste Skink (the exact one we got for Britain) for the American tech tree with just a default camouflage change:
American:
British:
The Skink Anti Aircraft 20mm Quad prototype tank(s) IRL had a different armament re-fitting of both the 20mm Hispano-Suiza aircraft cannon AND the simpler Oerlikon-designed Polsten 20mm cannons later after:
Hispano-Suiza:
Polsten: (note the casing around the barrels)
We basically could have gotten a more unique “Skink” for the American tech tree in the form of a way more faster-firing Hispano-Suiza Tipo 404 20mm cannons having 700 RPM and a slightly different designed turret rather than just the same Polsten-equipped 20mm Skink stuck with 450 RPM from the British tech tree. It’s also worth noting that the change from Hispano to Polsten actually caused historical issues in the form of reloading being only shortened magazine-fed while also having fitting issues with the gun itself.
I just wish certain vehicles would just stop downright being copypasted entirely when there are also certain changes they could add to make them more unique and different instead of grinding them out again in yet another tree. : /
