The Type 31 Field Uniform consists of a breathable synthetic fabric shirt and trousers; it can be worn inside of synthetic-core power armor or it can be worn with its accessories (vest, boots, and helmet) for traditional infantry combat.

Designed in YE 30, the Star Army of Yamatai Type 31 Field Uniform was designed to provide soldiers in the planetary forces with a more versatile and tactically useful uniform than the colorful duty uniforms. All items in the set are available in Black, White, Bluish Gray, or Star Army Camouflage. Because the field uniform is meant to be usable in armor, no metal pins are allowed on it; ranks are fabric patches attached by a hook-and-pile system.
