During their campaign to retake the planet Isstvan V, the detachment of Desert Lions was accompanied by an attached cohort of Legio Cybernetica robots. The chapter's attack on the planet's defense forts were preceded by this cohort, all of which had been programmed to advance on the defenses in an apparently mindless fashion. While they were easily destroyed by the forts' defenders, they succeeded in their mission - to map out the defenders' fire-plans and blind spots. Armed with this tremendously useful information, the Desert Lions launched their attack, losing only seven Marines in the process. Those robots whom survived the battle were afterwards inducted into the chapter as honorary members as a mark of respect.
