The ST-02 Commissar is a mobile frame in the Solar Calendar setting.


Originally called the Conscript, the ST-02 was developed decades ago for combat logistics. However, with the advent of the modern ST-03 standard, the incompatible 02 quickly fell out of favor. Repurposed as a labor frame to recover development costs, Oster Mobile has inadvertently been selling military hardware ever since to every colony in the Solar Union. With the addition of a sensor package making up for its weaknesses, the Commissar now performs valuable scouting and field command missions for many Free Colony cells.
