note: this is 3-plate-fig scale, the stack of 3 studs/1x1 round plates on the mecha base represents a pilot or other humanoid minifigure.
a relatively typical ground type mecha, equipped with a rotary autocannon in its left hand along with extra magazines stowed on its backpack, and a larger caliber shoulder-mounted cannon more like a tanks main gun in its right hand. small manipulator arms (the u clip) are installed on the front torso for combat engineering tasks.
I love the idea of using mini figs for building mecha.
