Maxwell Dynamics ST-10 Sandstorm Unconventional-warfare Tactical Vehicle (UTV)

The Sandstorm was a light-armored, two-person, side-by-side, all-terrain vehicle. It was designed by General Dynamics in the late nineties for the Special Forces community. It was meant to replace the various commercial side-by-side all-terrain vehicles then in use by the US Army’s Special Forces, Combat Applications Group (CAG, or more commonly known as Delta Force), United States Marine Corps Forces Special Operations Command (MARSOC) and the US Navy’s SEAL teams. The final design crossed the looks of a side-by-side sport all-terrain vehicle and a dune buggy. It was rugged, fast, but unarmed and lightly armored. It was powered by a 660cc Single-Cylinder flex fuel engine with a continuously variable transmission (CVT). The engine could burn bio-diesel, diesel, JP-8, kerosene or various other hydrocarbon-based fuels.

After the end of the First Robotech War Maxwell Dynamics acquired the rights for the ST-10 with its acquisition of General Dynamics. The design went back into production and was purchased by the United Earth Defense Force (UEDF) for their Special Purpose Divisions. Most were used Reconnaissance Division, the Forest Division, the Desert Division and the Jungle Division. Maxwell Dynamics also pushed it on the Reconnaissance Expeditionary Force (REF) for use by their Special Warfare troops. The acquisition of the ST-10 was frivolous, as the Special Forces community in the REF preferred to use hover vehicles such as the HR-32 Flash-Clapper. Because of this, most Sandstorms did not come out of their shipping containers for the duration of the Sentinels Campaign. The ST-10 received a new lease on life during the Invid Occupation. It had a flex fuel engine that gave it respectable range and allowed operation near the Invid without fear of Protoculture emissions detection.
