Fang of the Sun Dougram is one of my favorite mecha series, and the old toys are fantastic. The 1/144 series manages to strike a great balance of diecast, solid construction, and sharp details into a small size that allows for army building and some nice Real Robot diorama action. Here’s an Earth Federation patrol on maneuvers in the desert.
Spotted by a recon flyover.

They don’t usually deploy bipeds in the desert :3
