The Oculus Quad is a quadrupedal assault mech, which is usually paired with a Bipedal Assault Mech on the battlefield.  The front sled legs each hold an ion pulse cannon which fires a massive ion burst disabling everything in its path.  A 50mm rifle mounted on the top rear protects this mech from being flanked.  Like its bi-pedal cousin, BAM, the Oculus Quad has 11 inch thick bullet-proof armor.  Mounted in front is a double sensor / camera giving this mech its “Oculus” designation.
