Twin-linked weapons are two ranged weapons of any type that share the same targeting information and fire actuation link. This system allows the linked weapons to be fired in tandem, increasing their destructive power. Twin-linked weapons are most often deployed by the forces of the Imperium of Man, and most types of Imperial ranged weapons deployed on armoured vehicles or aircraft can be twin-linked. Tau Battlesuits and Eldar vehicles such as War Walkers have been seen making use of twin-linked weaponry, as have Orks wealthy and strong enough to bully one of their Mekboy engineers to upgrade their Shoota. Even the Tyranids have started to outfit some of their larger bioforms with two versions of the same ranged Biomorph to improve the bioform's chances of hitting its target.
