These are automated RLS units (Remote Linked Strikers). They were developed in the rouge colonies using common linked construction robot control technology and outlawed striker AI systems. The one on the left is an anti-armor version whose main armament is turret mounted rail gun with a small targeting laser attached. It has dual undermounted heavy gattling guns and pivoting shoulder mounted launchers (capable of firing several kinds of shells) for secondary weapons. It also has telescoping arms with reinforced claw like hands. The RLS unit on the right is an anti-personnel version with a single high velocity gattling gun as it's primary weapon. It also has two sets of shoulder launchers capable of firing smoke, chaff, flares, or grenades. A large, back mounted ammo bin stores enough rounds for the main gun to last through most missions and can easily be replaced, making rearming very quick. Serrated pinchers on each arm provide hand to hand combat capabilities if the unit is unable to resupply. RLS units were developed before the much larger JAK units and were actually the prototypes for that system. Whereas JAK units rely on an extremely complex remote interface that controllers are able to jack into, the earlier system relied mostly on mimic units built into power armor. The operators in the special powered armor could transfer their movements to the RLS robots. The downside to the system was that fine control still had to be handled by AI computers, it was difficult to control more than one unit at a time, and the operator had to be physically present on the battlefield. Within a decade the RLS units were replaced by larger piloted versions, which were in turn quickly replaced by remote control JAK units.
