PMX-1-1B: The A model's production version and far more common. Originally deployed to federal military units and later replaced or upgraded to C models. The left over B's would later end up as test subjects, trainers, and mercenary high end equipment.
Changed it up this time, slightly different post effects and this one done in pen. Other missing elements entirely intentional.
Edit: Shown here on the left shoulder is a multi-short-ranged UAV launcher. The legs feature 6-legged UGV's rather than the normal Anti-personnel/Reactive-armor. The load-out shown is more of an information warfare support setup. Ironically while not suited for CQC, the left arm weapon is an explosive shotgun.
Oh, and the lines this time were (mostly) by pen. Yeah, I said it.
