lol Rip XD

As for my tanks, use the inspirations behind them:

The light tank is a m24 chaffe
the mid tank is a m4 sherman
the heavy tank is a churchill 
the SPG is a T95
[/quote]Well, my heavy tank is more like a King Tiger or IS-2 in power.
Albeit my Feredyr tank destroyers have no chance to penetrate the front armor of your heavy tanks. Maybe it works on the medium tanks especially if these are early type Shermans.
As for mine, I upped the front armor protection of the later Arqwyen tanks to 50mm. That combined with the sloped design may give them medium-ish protection from the front but otherwise it's vulnerable as always.
Though be careful of my firepower.
33mm autocannons on 600RPM can be quite devastating anything not armored up sufficiently. But I think your nation has intimate experience of those from the last Yamatai-Yllendthyr War.
