The M10 "Linus" was utilized by American Trade Union in the Gasoline Wars. Though the Linus is popularly seen as the foil to the RCC's Orlan, filling a similar recon/light attack role, both have logged many times more kills on larger vehicles rather than each other.
Though the Linus lacks the straight-line speed and open-field mobility of the sleek, well tuned, low-slung Orlan, it is far more agile. In addition, its low turning profile and narrow shape make it a much more ideal infiltrator, even if its combat load is less versatile. When Linuses did engage Orlan squads, they would often only suceed through ambush from good cover where the Orlans couldn't follow.
Props to shinigami195 for doing the miniature-base thing in the first place, as it's a cool idea. I love rendering little slices of terrain under my robots and not having to worry about a scene background. It lets the design stand out better.
I'm working on a remake of its rival, the Orlan, in the same style.
