Please Read the Notes section for kinda important details.

The AMH.55 is a 3rd generation main battle tank in service with the Royal Army and Royal Marine Corps. It was designed to replace the aeging main battle tanks of the Royal Army and is equipped with the latest technologies.

HISTORY
During the North Eastern Conflicts, Royal Army Command decided to replace both of their MBTs, the Golem Mk.IX and the Thunderbolt I. The Golem with emphasis on firepower and armor, akin to a heavy tank, and with the Thunderbolt having an emphasis on manueverability and speed. the XMH program was initiated to replace both of these designs, combing their strengths into one vehicle. The new tank which was now named Thunderbolt II, was to be armed with a 130mm smoothbore gun, the newly developed Stroheim composite armor, and a multi-fuel turbine engine. The first prototype was completed in five years after delays and design changes, and the Thunderbolt IIA1 entered service eight years after the program's birth.

DESIGN
The Thunderbolt II was the first MBT of the Royal Army to have a three man crew, a commander, gunner, and driver. This was due to the fact that it was equipped with a bustle autoloader. The engine is a 1,500hp turbine engine which was notorious for guzzling fuel, but later models had larger fuel tanks and a much more efficient engine. The Stroheim armor has a classified composition, but was designed to defeat both shaped charged warheads and kinetic projectiles. The main armament is the GR.130/50A2C smoothbore cannon capable of firing different types of ammunition.

URSA T-2
The URSA(Urban Survival Add-on) is a heavy modification first seen during the early days of the SCW. It was revealed that Thunderbolt II's were vulnerable in urban warfare, especially against newer tandem shaped warheads which either penetrated the sides of the tank or heavily damaged the Stroheim. Crews would hastily modify their tanks to protect from these threats, and eventually they were given the URSA pack. The URSA T-1 was the first modification, mainly for additional composite armor on the turret to protect the tank against tandem shape warheads, though they were also capable of stopping some APFSDS rounds. URSA T-2 is the most major upgrade, giving the tank additional hull armor in the form of composite and ERA, slat armor in the rear, additional smoke/anti-personell grenade launchers, a remote controlled .50, and the Lyre Mk.III hard kill APS. These upgrades made the Thunderbolt II very lethal, and soon most Thunderbolt IIs left the factory in this configuration. Though meant for urban, close quarters combat, the URSA T-1/2 did not prohibit the Thunderbolt in long-range engagements.

NOTES
THis is probably my 5th attempt in building a tank with the same name, and I think this is my favourite. I went all out on it, using all of the knowledge I know. Now, due to the amount of parts and moving parts, she makes my game really lag, and thus after I' completed her, I couldn't test her out fully. So if your device can run her smoothly, know that there are a few stuff I might've missed, some oversights and miss behaviours, and for that I apologize. Otherwise, enjoy.
