Kill-team Cassius was designated an Aquila Kill-team. In many ways, these kill-teams are a microcosm of the Deathwatch itself, for they comprise battle-brothers drawn from multiple Chapters, each bringing their own specialised tactics and favoured armaments to strengthen the team as a whole. Rather than specialise in the destruction of particular xenos species or strategic assets, Aquila Kill-teams are generalist squads whose strength lies in their capacity to adapt swiftly and decisively to new battlefield challenges as they arise.
