Photon caster

An XV9 Hazard Battlesuit's Photon Caster units

A Photon Caster is a T'au defensive technology that all XV9 Hazard Battlesuits have mounted upon their forward knee armour. Operating in a similar fashion to Photon Grenades, Photon Casters are designed to be used in the situation that enemy forces advance too close to the Battlesuit, and repel attackers with a dazzling pulse of multi-spectrum light and a deafening sonic burst.

This will often blind and disorient attackers, confusing them and slowing their charge so that the Battlesuit is able to respond with further volleys of lethal firepower.
