The Computer Assisted Biologically Augmented Lifeform (originally named Computer Assisted Bio-organic Artificial Life-form) is a sinister and highly advanced sentient AI created by Kane using technology and data he acquired, presumably from the Tacitus.

CABAL's purpose was twofold: it served as a console interface between Nod battlefield soldiers and their commanders worldwide, while at the same time utilizing the subsequent and vast network of live intelligence to collate and devise complex strategies of its own, ultimately acting as a potent advisor and right-hand to those highest in command of the Brotherhood's forces.

It also proved to have the capability of decoding and translating the Tacitus, an object considered to hold all the recorded knowledge on the mysterious Tiberium substance. CABAL's overall function was parallel to GDI's EVA to a large degree, but was vastly superior. CABAL even referred to the GDI EVA as a "primitive machine". The AI literally had a mind of its own and could both reason and act completely autonomously, a lifeform more than a computer. The EVA unit, in comparison, gives at best logically-formulated advice based on the sum of the information it was presented with.

During the Second Tiberium War, CABAL was used as the Brotherhood's tactical, logistical and global communications coordinating console, as well as a potent type of advisor to Kane's top operatives under the command of Anton Slavik.
