KX139 Ta'Unar Supremacy Armour
If the Stormsurge Ballistic Suit was considered the Tau's first foray into Titan death machines, the KX139 Ta'Unar Supremacy Armour would be the Tau's first attempt at mass producing these fuckers.
The Ta'Unar Supremacy Armour truly is, the Metal Gear Rex of the army.
Overview
The largest class of Battlesuit in the Tau inventory, it is intended to meet a threat that the Tau Empire has not yet prepared for; the defense of worlds within their growing domain from the threat of other galactic races. Designed to counter anything from Imperial Knights to monstrous Tyranid bio-titans, the KX139 lacks the maneuverability of other battlesuits, and is instead intended for balls out firepower. Earth Caste engineer Fio’o Ke’lshan Sho’aun developed the KX139 to mount a dynamic yet stoic defense against the enemies of the Tau Empire. Development began after it was found that Tau heavy flyers such as the Manta were often outclassed in the form of a gratuitous amount of Flakk cannons.
The KX139 bristles with weaponry, with its primary armament being a back-mounted Pulse Ordnance Multi-Driver or Nexus Meteor Missile System. Additional weaponry includes triple Ion Cannons or Fusion Eradicators on each arm and two chest-mounted stations known as the Vigilence Defence System with Burst Cannons and Missile Pods. Other weapons options include a Heavy Rail Cannon Array with Fragmentation Cluster Shell Launcher. Protection is provided by a Barrier Shield Generator, which can withstand even Titan-class weaponry.
Crunch
When it comes to 9th Edition, this Metal Gear comes with 4 Smart Missile Systems, 4 Burst Cannons, 1 Pulse Ordnance System (that can be swapped for a Nexus Meteor Missile System or a Heavy Rail Cannon with Cluster Shells ability), and 2 Tri-Axis Ion Cannons (that can be swapped for Fusion Eradicators). T8, 30W, 3+/5++ makes it a bit more durable than a Knight. It can fire its non-Macro weaponry while in melee and it may reroll 1's when firing the Burst Cannons and Smart Missile Systems in Overwatch. It can move through any unit without Fly or Titanic, however, it cannot Fall Back and still fire that turn.
