Warhammer Horus Heresy Vultarax Stratos-Automata

Vultarax automata make use of a complex cortex unit that allows them to control the various gravitic impellers and jets that hold them aloft, and grant them more affinity for independent action. While the Magos of the Mechanicum employ the Vultarax as a forward unit, ranging ahead to engage and harass the foe, those automata they grant the Skitarii Conclaves are employed primarily as scout surveyors. In this secondary role, the Mechanicum permit some Stratos-automata to be retrofitted with additional auspex scanning arrays.
