Iwata-class super-heavy assault walker

The Iwata-class super-heavy assault walker is a super-heavy walker capable of acting as a mobile troop carrier, forward base and heavy weapons platform. Standing at 27.2 metres tall, the Iwata-class is the largest vehicle in the Yamatai Imperial Army's arsenal. It is propelled by eight legs and carries numerous weapons systems, and is able to carry an entire platoon of troops in addition to its large crew. The Iwata-class walker's combat role is to exploit breaks in enemy lines and allow for an intimidating mobile command post capable of front-line combat, unlike other command vehicles such as the Type-660 command vehicle, which even if deployed close to the front cannot actively contribute to the fighting. For defensive purposes, the Iwata-class is equipped with armour similar to that mounted on spaceborne destroyers, and also has five CIWS units and ECM capabilities to intercept incoming missiles.

Deployment
Its massive size makes it difficult to deploy it from space-to-ground as with more conventional vehicles. As such, it is typically brought to the surface in pieces and constructed there. Only the colossal Kashima-class heavy lander is able to deploy an Iwata-class to the surface in one piece, though the walker's legs have to be "folded" for storage.

Variants
Thus far few actual variants of the Iwata-class have emerged, with most "variants" often the result of battlefield modifications. An underwater variant has apparently been tested on Cheongsu, with the ability to resupply submersibles and primarily designed for shallow-water activities. Yet another experimental variant has the entire upper assembly removed and replaced with a massive ground-to-space cannon. This variant has been spotted undergoing trials on the uninhabitable planet Benzaiten-4-5.

Availability
Only the Yamatai Imperial Army is able to obtain the Iwata-class SHAW. No provincial army is allowed to purchase any units.
