This YE 31 uniform was introduced in the second half of YE 31 during the onset of the Second Mishhuvurthyar War, replacing the Star Army Female Bodysuit, Type 21. Designed for use on Star Army starships, the rugged new uniform is suitable for technicians, combat teams, starfighter pilots, and can be worn inside the Mindy 3 or Ke-M2-4 Series "Mindy" Armor. It is available in male and female versions and is the first uniform to be worn with rank patches instead of rank pins.
The Type 31 Working Uniform consists of dark tactical blue pants (with built in kneepads for ship maintenance work or field work), and a form-fitting dark blue shirt with the upper portion and shoulders clad in an occupational uniform color (the colored section has a sky blue lining). The Mandarin-style collar is dark blue. The uniform is worn with a police-style utility pistol belt (Star Army Utility Belt, Type 32), boots, and gloves. The belt, boots, and gloves are in matching blue-gray.
As of July 1, YE 38, it is permitted for soldiers to roll their sleeves up with this uniform. The sleeves should be rolled up to slightly above the elbow and the thickness of the roll should be around 4 fingers in width.
Metal insignia pins shall not be worn on working uniforms when they might present a safety hazard (e.g. FOD).
Since the start of YE 35, a navy blue baseball cap is authorized for wear with this uniform when it is worn outdoors. The cap is authorized to have patches sewn on the front and rear that are embroidered with a starship name and registry number or with the name of a duty station such as a fort or other installation. These caps are not standard issue items and can be obtained through ship stores or civilian markets at the ship captain or unit commander's discretion.
