The OSR-3M is a 60-ton skirmisher that fights at stand-off range, a 3088 rebuild of the 2511 OSR-2C. Where the OSR-2C carried a Large Laser and Medium Laser in each torso with a plain SRM 4, this variant fields an ER Large Laser and ER Medium Laser in each of the Left Torso and Right Torso, with the Streak SRM 4 replacing the older launcher in the Right Torso. CASE lines the Right Torso, and a supercharger in the Center Torso pushes sprint speed to 108 km/h when engaged, well above the 54 km/h cruise and 86 km/h top speed shared with the original. Light ferro-fibrous armor replaces the OSR-2C's standard plating, and the heat-sink count drops from 15 single to 12 double. The type keeps its low, hard-to-target silhouette, and Ronin Incorporated builds it at Wallis.
