Osiris OSR-4D

The Osiris OSR-4D is a 30-ton striker that fights close in, cruising at 86 km/h and topping out near 130, with jump jets carrying it 240 metres, twice the reach of the 3063 OSR-3D. In place of the SRM 6 in the left arm and the Machine Gun in the left torso, this variant leaves the left arm unarmed and adds a Medium Pulse Laser to the right torso alongside an ER Medium Laser. The ER Medium Laser in the right arm and the ER Medium Laser in the center torso carry over from the OSR-3D. Achernar Battlemechs builds it at New Avalon and Cahokia.
