M6 Tracker - all terrain mobile walker unit
When the military reached the west coast to reclaim the land inhabited by feral machines, the land was covered in ruins, many withering superstructures forming massive chasms and scars across land inaccessible to tracked vehicles.
Thus a need for a combat vehicle capable of scaling this new geographic environment arose, leading to creation of tracker unit.
Tracker has multiple limbs, two of them being strong enough to support whole body with entire weight on a single limb alone. These limbs allow tracker to explore devastated urban jungle with ease, while also capable of suppressing recoil from its powerful 20mm cannon rifle, making it the most versatile and reliable support unit on the west coast frontier
