The Aktaeus is the most recognisable of the Ordinatus Minoris created and operated by the Mechanicum, a super-heavy transport designed to carve a path through the stony heart of a world to deliver its cargo of warriors to the centre of the battlefield. Known to the armies of the Emperor as the Imperial Mole, this vehicle is employed primarily as a siege engine capable of rendering even the most formidable fortifications pointless by burrowing beneath them.
