I've been re-reading the Star League sourcebook recently, specially in the Reunification War section. The Star League through massive formations at the Periphery, with Outworlds Alliance facing two Corps (6 Divisions of BattleMechs, not counting other things....) with brigades of Kurita forces. Alliance only had a regiment worth of Light 'Mechs, a 3-Regiment 'Mech brigade secretly gifted to them from disgruntle nobility of House Davion, and large quanity of anti-'Mech irregular infantry. They (the Alliance) held them off for five years, with resources being drawn to the Taurian fight. Its going be interesting how things will be layed out in the Historical. Using Battle Force? War Chest System like Era Reports?
