An armored construct designed and built with the express purpose of operating on the frontlines, Frank is considerably bulky, numerous layers of armor of various sorts bolted onto its chassis. Standing at an even ten feet tall (thirteen, if you include the retractable communications and sensor array), the Cavalry Mk. XVII model carries itself upon two thick, heavily armored legs calibrated for optimal balance when handling high-recoil armaments.

Its torso forms the bulk of the automaton, easily five feet wide and boasting the thickest armor plates, as well as the identification barcode, dark gray and blue colors, and rank sigil characteristic of warmachines of the Arcturus Synthetic Collective. A pair of mechanical arms extend from either side of the torso, augmented with enough actuators and servos to lift a moderately-sized building, each limb thus being capable of carrying two weapons systems normally found on tanks.

Atop the walker rests its primary sensory receivers, a somewhat head-sized armored block with 360 degrees of movement along its socket. The mounted combat optics array occupies the bulk of this area, a large primary lens ringed on one side by four smaller lenses, all of which emanate a bright green glow. Lastly, the vast majority of Frank's utilities can be found on its back, a vast number of systems and devices all integrated into an Advanced Combat and Command Module.
