Osiris OSR-5D

The OSR-5D is a 3081 rebuild of the 3063 OSR-3D, a 30-ton striker. Where the OSR-3D carried an SRM 6, a pair of ER medium lasers in each arm and torso locations, and a machine gun, this configuration strips all of that away for a single Heavy PPC in the right torso. A lighter 210 XL fusion engine replaces the 240 XL unit, dropping cruising speed from 86 to 76 km/h and top speed from 130 to 119 km/h, while jump range grows from 120 to 210 metres. Light ferro-fibrous armor replaces the base model's ferro-fibrous plating. Achernar Battlemechs builds it at Cahokia.
