Okay, threw a sort-of veteran choir against a veteran battalion of Lyran regulars- Lyrans had about 10k more BV . . .
Did not play it all the way out, but I oopsed a bit on the TSM- was just too hard to try to regulate it, it maybe more of a 'strategic' feature than a tactical for most loadouts. While the Shadow troops lost, they managed to kill a Devastator, Black Hawk KU, Grand Titan (woo, ammo TAC, lol), Shadow Hawk IIC w/PCs, Thanatos 4S, LB-20X Thanatos and I think 1 more heavy. Managed to cripple a Ottscout, Hollander, Ostol, Phoenix Hawk 7S, and Stinger so they were either in forced withdraw or KO'd from falling. Still in the fight but badly torn up were a Phoenix Hawk 3S, Warhammer 7S, Valkyrie, Shadow Hawk C, and another medium.
The above were the results before I called it where the Archangel and IJJ/ERML Preta were all that remained . . . so five mechs, 6 BA and a vehicle to put a battalion to a bit better than 50% strength.
