The Onager Dunecrawler takes its heritage from ancient exploratory vehicles, its distinctive crawling gait allowing it to traverse ground that would defeat wheeled or tracked machines. In the service of the Skitarii it has been refined into a formidable battle engine, its central hull housing a powerful primary weapon and its frame protected by heavy armour and, often, a projected shield that turns aside incoming fire.
The versatility of the Onager lies in its interchangeable armament. It may carry a neutron laser that punches through the heaviest armour with contemptuous ease, an eradication beamer that boils away infantry and structures alike, an Icarus array to scythe enemy aircraft from the sky, or a heavy phosphor blaster to mark and burn the foe. Whatever its configuration, it brings weighty firepower to bear in support of the advancing legion.
Tough and dependable, the Dunecrawler anchors Skitarii battle lines, absorbing punishment while delivering precise and destructive fire. Its machine spirit is honoured with careful ritual, and its crawling advance across the battlefield is a familiar and reassuring sight to the cybernetic soldiery it protects, a mobile bastion of the Omnissiah's wrath.
