This is a 15mm (1/100) scale model of a late production Neugen Type B Main Combat Walker. It stands about 6cm tall.
As the war dragged on, many of the older Offworld Neugen A walkers were refitted with heavier armor, and had many of their auxillary systems removed or replaced. This made repair and resupply of these prized assets a lot easier and helped ease the strain on the supply chain of the alliance.
