Griffin GRF-2N is a Medium-class 'Mech in Battletech.
The Griffin 2N is an old Star League model that was among the most versatile 'Mechs in its heyday. Its weapons generated a lot of heat, but the old Double Heat Sinks were put in to handle it. It's almost impossible to find those anymore, though.
SRM Brawler - Arguably the best Medium-Class Brawler, the 2N variant can comfortably fit 4 x SRM6 w/ 3 tons of ammunition and full jump jets to act as an effective mobile "shotgun", with remaining tonnage left over for additional armor, heat sinks, or more lasers.
The 2N variant has the highest available tonnage of all medium-class 'mechs currently in the game.
