Type 6 Chi-Yo tank

The Type 6 Chi-Yo (6式戦車 チヨ) is a Yamataian next generation main battle tank designed and produced by Mitsuhishi Heavy Industries. The Type 6 is intended to complement the main battle tanks and eventually replace the  tanks. Compared to other main battle tanks in the Yamatai Imperial Army, the Type 6 has been equipped with enhancements in its capability to carry out long-range offensive anti-tank warfare, specifically with a land war on the Central Escaric plains in mind.

The tank entered service with the Imperial Army in 2016, and the Imperial Army is the main operator of the Type 6. Three main versions of the Type 6 have been developed, the Type-12 prototype, Type 6, and the Type 6 Kai. The Type 6's deployment has been lessened due to its high cost, with the older and  tanks serving as the primary main battle tanks of the Imperial Army.

Deployment
By 2020, 100 Type 6 tanks have been deployed to the Yamatai Mainland Ground Defence Force deployed in Chisei. The Type 6 has seen less deployment than other tanks in the Imperial Army due to cost factors. The Type 99 is instead the primary main battle tank of the Imperial Army and has been built in far higher numbers than the Type 6.

Armament
The main armament is a 2-plane stabilised 120 mm Sukimoto Type-99 smoothbore gun with a mechanical bustle autoloader (conveyor-belt type), identical to that used on the Type 99. The gun may be fired under computerised or manual control. The tank can carry 42 rounds including 22 in the autoloader. The autoloader can reload in around two seconds, and the practical auto-loading and firing cycle for one target is around 4–6 seconds. The gun is capable of firing APFSDS-T, HEAT, Frag-HE-T, and gun-launched tandem shaped charged ATGMs with a range of up to 5 kilometres.

Secondary armament consists of a 12.7 mm machine gun on the commander's cupola and a coaxial 7.62 mm MG.
