Infantry tank Mk.III Churchill VII was a brittish infantry/heavy tank of WW2, designed to support infantry attacks and clearing fortifications. it had one of the thickest armor platings of it's time, and was invunurable against most german anti-tank weaponry. it's main gun wasnt that powerfull, only a 6-pounder, but it did get aditional firepower upgrades later in the war, such as the churchill crocodile (added a flamethrower) or the churchill HAVRE (replaced main gun with a heavy mortar to convert it into attillery)
last picture is with the muzzle brake.
this tank is gunless as-is but does have internal hovers already added to it. you can mount any weapon you want but i advice disintregrators for good firepower at all ranges and against any target.
