My results of the battle would have definitely impacted the diplomacy . . .
The First Tyr assault mech star was 2 Kodiak 6s, Executioner (chose L for some range), Mad Dog S, Mad Dog III Prime. Vehicle star was wonky too, 3 Hachiman (AAA) . . . random rolls, lol.
Meanwhile the Pact force ended up with 3 Falcon heavies (Shadow Cat II 4, Jade Hawk 2, Hel Prime) along with a LOT of mixed tech like the Crusader 10S, Flashman 10E, and Atlas 8-S which resulted in a lot of Gauss Rifles & Heavy Gauss Rifle (6 combined). Also ended up with a Marksman (LPPC) as a heavy vehicle which drifted a round right onto some Elementals.
Pact got lucky . . . same turn a Hollander II hiding in the trees put a Gauss slug (only hit for everything on 10s) into one Kodiak's CT for 2 TACs, engine & gyro. Other Kodiak had a TSM active Hatchetman jump behind it after taking a Gauss slug to the LTR . . . which the Hatchetman put his hatchet into the gaping wound that turn. While the backshot Kodiak and Mad Dog III Prime wrecked the Shadow Cat II 4 in that same exchange, it still managed to put a Gauss and LRMs into the Mad Dog III's side torso to open it up & crit a LRM20.
In one turn, while the Pact lost a single heavy mech the Bears had two assaults crippled into forced withdraw and a heavy get beat on too.
