TX-81 Battle Fortress

The TX-81 Battle Fortress is the largest tank ever built by the Quantonian Empire, The TX-81 is 20 meters tall with 10 sets of tracks where each track is on average 6 and a half meters wide, which the length of average 19 meters to compensate the weight. The TX-81 has two mega railguns on the turret that is on top the tank, 4 rocket pod turrets on the front, rear, left and right sides that can elevate themselves when firing and high caliber machine gun turrets all around it. The TX-81 runs off of a fusion reactor which disables itself when the tank takes too much damage which then the tank activates reserve power generators. The TX-81 weights 30'000 Tonnes.
The TX-81 can drive up to 30 miles per hour on flat terrain which is thanks to its fusion reactor, the reserve generators make the TX-81 drive up to 5 miles per hour as these generators run off basic fuel sources from solar power and petrol.
The TX-81 was first designed by a mad yet intelligent scientist at 12/05/1100 because he feared of the upcoming Second Great War. However the Quantonian Empire denied his idea as they did not have the technology to build a power generator strong enough to run the vehicle, however the empire won the war anyway with the technology they had.
The TX-81 was eventually first built at 24/10/3040 with up to date equipment. At least 100 of these battle fortresses have been built.
The TX-81 requires a crew of 200 men, 100 of them being the tanks security crew in case some lucky bad guy climbs up the side of it and 50 to be the pilots of the tanks weapon systems, the other 50 are to drive the tank and maintain it.
The TX-81 has a self destruct system which causes a mini nuclear explosion upon detonation, this is only used if a TX-81 is captured by the enemy which then the empire lets them send it to their base so then they can detonate it.
The TX-81 has the ability to raise the tracks into the tank so the battle fortress can be a tactical defense/offense emplacement.
The TX-81 has 4 entrances, a metal hatch underneath between the tracks but is used only as an emergency exit and is locked from the outside when engine is on. Two ladders on either side that are connected to the exterior catwalk and can be retracted. A hatch on the top behind the railgun turret. The Doors are as armored as the tank itself, the locks are also ultra secure and require two keys to open.
