Doctrina Imperatives walker unit focused on exterminating flying units.
Onager Dunecrawlers decimate the foes of the Skitarii whilst channelling great swathes of battlefield information to their masters high above. Squadrons of these versatile walkers clank to war in long columns that stalk forwards in uncanny unison, clambering over shattered ruins and wading through toxic run-off without breaking stride. The enemies of the Cult Mechanicus have good reason to fear the Dunecrawler, for these ornate monsters are protected by overlapping emanatus force fields, and bear some of the most esoteric and destructive tank-portable weaponry the Tech-Priests can devise.
