The Signum is a special communication device which allows the user to access a myriad of useful battlefield targeting data and pass that information on to their companions, allowing for more accurate and coordinated fire. Signums are available to members of a Deathwatch Kill-Team as well as normal Adeptus Astartes Techmarines, Devastator Sergeants and Techpriest Enginseers of the Imperial Guard. While useful on its own, pairing a signum with the interconnected autosenses of a squad of Space Marines allows them to strike their foe with deadly and inescapable coordinated precision.

目标指示器是一种特殊的通信设备，允许使用者访问无数有用的战场目标数据，并将这些信息传递给他们的同伴，从而实现更准确和协调的射击。死亡守望杀戮小队的成员以及普通星际战士的技术军士、毁灭者军士和帝国卫队的技术神甫工造士都可以使用标志。虽然其本身就很有用，但将一个目标指示器与一队星际战士相互连接的自动感知系统相结合，可使他们以致命且无可逃避的协同精度打击敌人。
