Thanks for the replies so far.
Sarna.net has Baranov with a Mech Battalion in 3058, and by 3067 with supporting elements. But I don't mind putting it at 2 battalions worth of Mechs and supporting units in 3065.
How about McNally? I'm thinking maybe a combined arms battalion total. A company each of Mechs and Armor, with 1-2 Infantry companies. Was McNally a Mechwarrior, or any sort of military veteran?
Ridzick brothers I've never seen anything about what they have. I believe they were mentioned in the old Chaos March book but didn't give any details. Per canon I believe they are no longer a factor around the 3065-67 time frame, but as I said this is for an AU so I'm keeping them around.
What about Wobbies? Any troops or advisors helping out Baranov?
