Owing its origin to the lost knowledge of millennia, the Onager Dunecrawler light walking tank, is based on the Mars Universal Land Engine; itself inspired by the bad-tempered beasts of burden that transported their masters across Holy Terra in ancient times. The Onager Dunecrawler, rather than being a mere people-carrier, is absolutely brimming with advanced, powerful weaponry.
Might well have been, originally. It harkens back to a time Mars was terraformed, in 40k, before it was nuked back to red wasteland normality.It looks like a farm vehicle.
