I reread Dominions Divided these last couple evenings and took some notes. Without a comprehensive Field Manual 3152 type product, I thought I might list out what I found and see if it was of any interest to the Inner Sphere aficionados we have here.
DCMS confirmed losses, as of June 31525th Sword of Light (Elite/Reliable) Destroyed on New Avalon, dying to the last MechWarrior when Kanrei Toranaga was captured.
2nd Genyosha (Veteran/Fanatical) Damaged on New Avalon, reformed with Ryuken-hachi as Black Sword. Destroyed on Greeley.
Ryuken-hachi (Elite/Fanatical) Damaged on New Avalon, reformed with 2nd Genyosha as Black Sword. Destroyed on Greeley.
Ryuken-san (Veteran/Reliable) Damaged in Dragon's Tongue campaign, Destroyed on Greeley.
11th Ghost (Veteran/Questionable) Damaged in Dragon's Tongue campaign, Destroyed on Greeley.
As with all BattleTech events, even when clearly stated that these commands were destroyed, there may be some survivors. They may even exist in paper shortly afterwards. Sword of Light, Genyosha, and Ryuken commands tend to get rebuilt. As to the timeframe, who can say. Personally, I've painted up 20 mechs in 5th Sword colors, so while I can always use them to represent the Combine, I'd love them to reform soon.
AFFS Losses, Conjecture5th Avalon Hussars LCT (Veteran/Reliable) Savaged on Plymouth fighting Black Sword, lost two companies on Mauckport to 2nd NS Regs.
1st Kestrel Grenadiers RCT (Elite/Fanatical) Fought on Mansfield, "crushed" in a pincer movement on Tsamma by the 2nd NS Regulars.
So strangely, there are no confirmed units destroyed for the AFFS. Between the Rec. Guides, and a few other sources, we've heard of Davion Irregulars and Davion Auxiliaries. Both appear again here in Dominions Divided. For example, the Second Davion Irregulars becomes the core of the new First Robinson Rangers. I'm wondering if between the lines, we can assume that units that took heavy losses would be reinforced or draw on these ad hoc units.
As for the Kestrel Grenadiers--back in 3025 they had some cool unit history. Feels like since then, I've never seen a unit described as Elite meet with so many losses. Poor guys are like the clown car of the AFFS, taking a literary beating to represent the fortunes of the nation.
Anyway, if anyone was curious, there you go.
