Ironstrider Ballistarius

Like its brother, the Sydonian Dragoon, the Ironstrider Ballistarius shares the same chicken leg design, however unlike the Dragoon the Ironstrider carries a twin Autocannons or Lascannons as well as downlinks providing them with the sum knowledge of their enemies, making it highly dangerous and efficient in eliminating important targets. These walkers travel along with their Skitarii Ranger brethren in search for high value targets. The Ironstrider's mechanized mounts are able to walk on the most hostile terrain, making it quick on uneven terrain even among other walkers. However due to this, this makes the servitor driving the thing to be the first components to fail, you would think the Mechanicus would spend some time in making their slavebots more resistant to things such as corrosive gasses and water. *sigh*.....more Mechanicus incompetence.
When in battle, the role of the Ironstriders is to act as a mobile artillery platform, making it a more longer range and more Dakka version of their Dragoon cousins. Due to their enhanced eye sight, it is thus, the role of an Ironstrider Ballistarii to hunt down enemy commanders and spiritual leaders in order to sow chaos and confusion within enemy ranks. When not hunting for a particular space pope nor an overgrown fungus or psychic Harry Potters, the Ironstriders form into groups called a Ironstrider Cavalier whose sole purpose is to shatter enemy formations as the quick speed, agility and firepower ensues that no enemy, even ones clad in Terminator armor or a Super-heavy tank would emerge unscathed.
Additionally, Ironstriders are able to see things in slow motion due to the combination of the downlinks mixed in with an intravenous dump of hyperfocus stimulants which hype up the already augmented senses of the rider. This ability is what allow Ironstriders to hit with such accuracy and grace that could rival even the smug, knife-ears and their chicken walkers. Thus it is of no surprise that Ironstriders are favored among the Mechanicus forces when out hunting for potential acheo-tech or a new STC.
