Grav-Inhibitor Drone

A Grav-Inhibitor Drone

A Grav-Inhibitor Drone (Kor’vesa in the Tau Lexicon) is a type of Tau Drone (small, sleek, disc-shaped, semi-sentient machines) employed extensively alongside Tau units in battle. Grav-Inhibitor Drones have to date only been deployed as part of Pathfinder reconnaissance teams during the Third Sphere Expansion. All Grav-Inhibitor Drones are equipped with a Gravity Wave Projector, which can emit a high-powered graviton wave that repulses nearby enemies, slowing their advance to a crawl or halting them in their tracks altogether. This allows Pathfinder Teams to move out of the way of an enemy assault and take the time to react to the assault in the most efficient manner.

Grav-Inhibitor Drones consist of an advanced processor unit, which individually has only a basic intelligence (approximately equal to that of a small animal such as a pterasquirrel), and moves about by way of a small anti-gravitic generator and a smaller and much modified version of a Tau Jetpack. This allows the Grav-Inhibitor Drone to hover over the ground and skim over most obstacles. As they hover over landscapes, rotating back and forth, their sensor vane constantly transmits vital information about their surroundings.

Grav-Inhibitor Drones that are attached to a Tau squad can be controlled by a Drone Controller, whether it is in the form of a support system for a Tau Battlesuit, or a hard-wired piece of wargear for Tau infantry. A Drone Controller is an electronic device that can be used by the Tau to further enhance their control over their robotic companions. A Drone Controller acts as a hub of digital communications between the Drone's operator and any Drones that are nearby the user. It serves as an advanced interface between the operator and the artificial intelligence (AI) combat programs of the Drones, and is often used to direct the Drones’ firepower far more efficiently and with a level of accuracy far greater than would otherwise be possible on the battlefield.

So deeply do the Tau believe in the Greater Good, that even their Drones are programmed with self-preservation protocols. In the face of what the AI deems to be hopeless odds, a Drone will attempt to escape rather than stand and fight. While in certain extreme circumstances Drones might be deployed on high-risk missions likely to lead to their destruction or purposefully moved to block enemy advances on units of Fire Warriors, the Tau do not consider Drones to be disposable units and the Drone artificial intelligence will analyse every possibility in order to ensure its own survival.
