OS-11A Twilight Fang One of Obsidian's high-performance light STs, developed based on the OS-06F Diana's combat data. The Twilight Fang's built-in "Fang" unit can forcibly calibrate the ST's actions when the pilot's operational accuracy is insufficient, ensuring mission completion. This ST was designed in two models—Model A, suitable for urban terrain, and Model B, for jungle and mountain warfare. Ultimately, Obsidian chose the more versatile Model B to be mass-produced.
