Markerlight

A markerlight is essentially a laser targeting system wieled by infantry and aimed like any other weapon. The markerlight itself does no damage, but it is common knowledge amongst the enemies of the Tau that anything with a tiny markerlight dot on it is going to die, soon. This small laser dot "paints" a target for heavy weapon systems to target with ease. When in use with a Railgun from a Hammerhead or Broadside, the target's destruction is almost certainly immenent. In addition, the markerlight can be used to give a squad instant support, as when a markerlight is fired, a signal can be sent to a remote seaker missile mounted on a vehicle to seek out the painted target and destroy it, completely independant of the vehicle.
