Until I see specific reports of a unit's death or disbandment, I'm assuming it still exists in a greatly reduced form. Galaxies reduced to Trinaries, Keshiks reduced to Stars, stuff like that. I fully expect a complete reorganization like what happened after the Refusal Was, but until we get IKEO, it hasn't happened yet.
Speaking of which, are there any Galaxies we KNOW are completely gone, aside from that one that fell into a Japan-shaped hole? No guesstimating or inferring here, I'm talking about ones where the book explicitly says "they're all dead or disbanded".
Marthe did some creative bookkeeping calling binaries trinaries, etc. but even she would struggle to not strike units from the rolls in this case.
Even reducing a cluster to just a trinary leaves falcons with, optimistically, 7 "clusters" of their pre-Terran 52 ish. Some units died. I expect some optimistic bookkeeping myself, but wildly optimistic bookkeeping leave falcons with a Keshik and two clusters.
Regarding your question, ilClan was probably intentionally mum on specifics, and I'm not rechecking HotW. These are specific losses/survivors called out
- Khan dead
- saKhan dead
- 1 Surviving Galaxy commander out of 12 (Stephanie Chistu)
- Forward Fire Battery Beta - 100% casualties. Whoever they were
- Seventh Falcon Striker Cluster - 100% losses.
- First Falcon Jaegers - 2 surviving warriors
- Third Falcon Velites surrendering after killing mongol commander.
- 7th Kommando's raid crippled falcon ASF assets with plenty of ASF jocks still alive
I suspect we'll get a more detailed look at the damage once IlClan's Eyes Only releases.
I expect you're right.
