Defending and policing this vast realm nearly 3000 worlds strong was the largest army eer known to humanity: the Star League Defense Force. Harnessing the largest fleet of WarShips ever assembled, the most advanced technologies in BattleMech and aerospace design, and the finest, most disciplined training regimens in known space, the SLDF was the invincible might that kept the feuding Houses of the Inners Sphere in line.
