The Type 34 Infantry tank was a Heavy tank that entered service in 1934, it is notable that it is the only multi-turreted tank that was mass produced and also being the first tank with a diesel engine.

Armament: The armament consist of One 57mm short barrelled Type 17 tank gun in the main turret (usable) and three 7.5mm Type 22 machine gun in three Auxillary turrets (unusable).

: Armour The tank hull is protected by 60mm of riveted stall plate, the main turret 50mm riveted steel, and auxillary turrets 27mm (I don't know how to add armour so let's just pretend that this tank have it)

Speed & range: Powered by 150hp Parkinson Diesel engine and had a top speed of 34kmh, it carries a large 110L fuel tank at the back of the tank.

Pros Have a very thick armour impervious to anti tank weaponry up to 25mm gun, three Auxillary turret gave it a 360° Arch of fire covering the entire tank

cons Have a large and noticeable fuel tank means it is surprisingly easy to incapacitated the tank, short barrelled gun meant that it can't effectively engage other tank outside of the Light tank category.

Most effective as:
Heavy breakthrough tank, smashing through enemy fortification and supporting infantry advance

Real life counterpart:
Type-95 heavy tank and T-35 heavy tank

Operational manual:
Group 1 is to activate main turret, trim is for traverse while VTOL is for elevation.

group 2 isto activate Front auxillary turrets, trim is for starboard auxillary turret's traverse while VTOL is for Port auxillary turret's traverse,
group3 is for aft auxillary turret, use trim to control the traverse
