RMS-179 GM II Semi-Striker
A custom-made close combat specialist GM II built from various spare parts at Torrington Base. Its most notable features (and the origin of its namesake) were the patch-on armor and twin-beam spear taken from a GM Striker. It fought admirably but was destroyed unceremoniously by the fearsome Efreet Schneid during the Zeon Remnants' assault on Torrington Base.
