A Failsafe Detonator is a powerful T'au explosive device that causes the bearer's T'au Battlesuit to self-destruct in a lethal explosion. This technology was developed to be used in only the most dire of circumstances and was intended to serve as the ultimate expression of the doctrine of the Greater Good.
With the pilot's sacrifice, he buys the rest of his squadmates time to withdraw and regroup in the face of overwhelming enemy forces. A Failsafe Detonator is a signature Support System available only to Battlesuit pilots of the rank of Shas'vre or higher.
