How about this?
AS-T15
The first of Arstotzka's glorious fighting engines.
An armoured shell made from the finest Arstotzkan steel. It has 55mm forward armor, 40mm side, 25mm rear and top, 10mm bottom
Fitted with 6 dreadnought wheels, the rear pair are driven by the the mighty AS-51 Superheated steam engine.
Armed with a single forward facing AS-1912 Artillery gun(capable of traversing 15 degrees) and a pair of AS-1910 Machine Guns in side turrets.
Traversable turret for 80mm gun is very complex stuff and while we only need to fire forward because we will move to assault enemy trenches. On other hand, machineguns need to fire in all directions because enemy infantry can get behind it
The AS-T15 should use tracks instead of wheels.
Alright, I'm
pretty sure this is what we're shooting for. Gonna be a lot of dice rolls. May Random.org be with you.
AS-T15: This is a steam-powered tank using the AS-51 S steam motor from Arstotzka's steam locomotive. In fact, it's mostly the enormous locomotive engine, which a rectangular armored shell. The armor is shaped in a half-cylinder, like an airplane hangar, except the front is cut at a 45 degree angle. Exit is through a hatch on top, which breaks up the smooth shape of the tank along with a couple chimneys. The armor is 20mm throughout. The only open space inside is towards the front of the tank, the engine is located in back and the sides along the engine are used for storing coal. The front of the tank has a gunner on the right side firing an 80mm cannon with a narrow, tank destroyer-like arc of fire. There isn't room for a lot of ammo. The driver sits in the left front, and there is an AS-1910 gunner on each side aiming through slats in the armor. Packed in between all of these people is a coal shoveler. The tracks are set on six rigid train wheels and follow a flat shape on the bottom of the tank, with a large wheel in the front and back. The tank becomes incredibly hot inside due to the coal boiler, hot enough to cause weapon malfunctions and heatstroke. It can exceed 50 degrees celsius in prolonged use, and the soldiers assigned to test it nickname it "The pressure cooker". Being mostly engine, it can reach 13 kph. The track system is complex, and the machine uses a great amount of material, which combine to make it Very Expensive.
Revision time! Could you guys label all your votes in
Bold? It will save me a lot of time tallying up after long discussions.
