A new tank is something I can completely support. We need something like the panther or tiger II in the face of their bulls.
UF-MT-41 'Demolisher'
Designed to take on the Cannalan 'Bull' tank and come out on top consistently, the Demolisher tank uses an enhanced 75mm cannon (Named the 'Butcher') using a falling block breach and semi-automatic action (meaning, it ejects the spent case automatically), as well as using a lengthened barrel and more propellant behind each shot with APCBC-HE-T being it's primary round (Copied from the rounds of our german allies). The gun is also designed to have a muzzle break and has a gyroscope to make mobile firing easy. 3 Sorraias are also included in the design; 1 coaxial, 1 hull & 1 cupola. Additionally, the tank's targeting sights are provided by eagle sight Mk. IIs arranged as a stereoscopic rangefinder, allowing it to massively outshoot the bull thanks it actually having sights.
In regards to armour the Demolisher mounts roughly 100mm on the front, 60mm on the sides, 40mm on the rear & 20mm on the top (With the turret being up-armoured slightly more than the hull). All the armour on the tank's hull is sloped, with both the front and sides sloped conventionally and the rear armour sloped out in reverse (AKA Akin to a Konigstiger or panther) with a stretched-out hexagonal turret. All the armour is RHA. Furthermore, reinforced slat amour is applied to the front and sides of the hull in order to protect against HEAT rounds.
A thick firewall separates the fighting compartment from the efficient V12 engine, lessening the risk of a fire taking out the crew or ammo. Wide treads with cowling ensures that even in the jungle mud the tank will be able to move smoothly. The tank also has a crew of five men (Commander, Gunner, Driver, Loader & Radio operator) co-ordinated by use of a tank intercom and radio headsets.
