Margen Type-C1 Light Combat Walker.
This is a 15mm (1/100) scale biped walker coming in at around 5.5cm tall. Second in the line of Orbital Bipeds, it was based off the heavier Neugen Chassis, removing a lot of the more expensive systems, instead replacing them with more easily manufactured indigenous components. The result was a cheaper, more cost-efficient weapons platform that served alongside the dwindling numbers of off-world Neugen Walkers till the end of the war.
