The 25th Arcturan Guards RCT seemed to survive the FCCW intact and ended up stationed on the Falcon border it seems on Mkuranga but no indication they were still there in '69 when they were destroyed. But I also cannot find what Falcon force they ended up fighting. With a mech regiment, 3 aero wings, 5 armor regiments (Gurti?), and 5 infantry regiments it would take quite a sizeable Falcon force to hammer what could be concentrated to face invaders even if the whole force could not be assembled in one place. I mean take it by 2/3s and you have 2 mech battalions, 3 armor regiments and 3 infantry regiments- it will take more than a cluster of Falcons IMO.
