I absolutely love this tank. Not only is it a breeze to put together, as it took me two hours to build and it went together so easily), but has so many little connotations that make it feel like what the lore says it is.
These tanks were commonplace during the Wars of Unification. Those brutal wars in the early years of the Imperium, before the Great Crusade.
For me what cements this are the details. Firstly, the two hull sponsons. Not the weapons themselves but the fact that there are these two weapon mounts placed here. For me this makes me think of the strange tank designs of the Interwar period, specifically the Vickers A9 Cruiser MkI with the two smaller turrets in front of the main turret and the MkI-IV tanks of WWI. Also the M3 Lee comes to mind here too. Whilst the Vicker A10 Cruiser MkII replaced these turrets with a front armour section that housed the driver and forward machine gunner, it is this change that brings me to the front hull section.
What is this little cupola to the right of what is clearly the driver. Is this where the commander can pop his head out and block the lens above him which is for something, the hull sponsons I guess. This little bit of weird design is reminiscent of the VK45.01(P), also called the Tiger (P) [(P) stands for Porsche, for those who may make the mistake it for prototype or production, although one did see combat the rest were repurposed].
It is that vision slit and then angled armour that makes me think of this. Save for the additional little lens, it is almost a like for like remake of that little section.
The turret itself has a bit of a mix of thoughts for myself, the almost dome turret fits in with the Deimos pattern predator and Fellblade turrets, but the option of taking a dome turret is a little archaic for me too. This turret type has been part of the design process for a nearly as long as the tank itself has been a design, with it being present on the Vickers A1E1 Independent (it had 5 turrets, the main one was domed), the Renault G1 and AMX-40 (duck tank) in earlier periods, whilst in later periods the M60 and T-55 (I'm pretty the USSR ran with this idea on their other tanks, under all their reactive armour).
It is all these little details that made this tank a great one for me.
Just don't get me started on why this wouldn't actually work as a tank.
