The Bruin is a Clan Ghost Bear assault BattleMech which was produced at the Dominion's Bergan Industries factory on Alshain. Its conception was to help unify and bolster the Inner Sphere economy while continuing integration with Clan Ghost Bear.[1]

The Bruin was designed by Bergan-C team, with mobility and psychological impact as the defining factors.[1]

Weapons and Equipment[edit]

The Bruin's long-range firepower includes a right arm mounted Omega 12-coil Gauss rifle and a center torso mounted Type X "Short Bow" LRM-10 Launcher. These two weapons give the 'Mech far reaching power, providing it the ability to penetrate an opponent's armor and damage its interior equipment.[1]

For its intermediate and short range brackets, the 'Mech is armed with a Clan Kolibri Delta Series Large Pulse Laser in its left arm and an Series 2f ER Medium Laser in each arm, along with a Smartshot Mark V Streak SRM-4 Launcher in each torso.[1]

To manage heat, it has been provided with 14 Clan tech Double Heat Sinks. Its hull is protected by 15 tons of standard Clan armor with integrated CASE.

The 'Mech 320 rated Extra Light Fusion Engine allows the Bruin to achieve a respectable running speed of 64 km/h. To enhance its movement, especially in rough terrain, it has been fitted with leg mounted Jump Jets.[1]
