Yeah, I figured as much that FM 3085 would be the sweet spot for doing the calculation, thanks anyways. I did some digging in the strategic games section and found a reasonable "balanced" composition in regards to Mech TO&E of the RCT's mech forces.
I have no way of calculating the cost of the infantry, but figured I can at least come up with averages for mechs, vehicles, ASF and transport assets like dropships and jumpships.
Instead of opting for a single faction, I tried to choose some across the board. It might be reasonable to assume some sort of C-Bill increase to the respective averages based on the unit rating. Maybe someone can figure something out that makes more or less sense?
Either way, here is my calculation:
Average Cost Assault Mech (3085 RAT, FedSuns): 16.831.193
Average Cost Heavy Mech (3085 RAT, FedSuns): 12.768.559
Average Cost Medium Mech (3085 RAT, FedSuns): 8.031.093
Average Cost Light Mech (3085 RAT, FedSuns): 3.744.335
Average Cost Assault/Heavy Vehicle (3085 RAT, LyrCom): 8.462.756
Average Cost Medium/Light Vehicle (3085 RAT, Dracs): 2.633.383
Average Cost ASF (3085 RAT, RotS): 10.596.601
Balanced RCT:
144 Mechs
->
light recon battalion (incl. 1 medium command lance) -> 4 mediums, 36 lights: 166.920.432
medium/heavy striker battalion (incl. 1 heavy command lance) -> 22 heavies, 18 mediums: 425.467.972
heavy/assault battalion (incl. 1 assault command lance) -> 22 assaults, 18 heavies: 600.120.308
Command Company BM Regiment (4 Assault/4 Heavy/4 Medium): 150.523.380
Command Company RCT Command (4 Assault/4 Heavy/4 Medium): 150.523.380
--> Mech total: 1.493.555.472
300 Heavy Vehicles: 2.538.826.800
1079 Light Vehicles: 2.841.420.257
40 ASF: 423.864.040
RCT (without transport assets, infantry and pure support elements): 7.297.666.569
Transport assets:
5 Overlord, 15 Triumph, 4 Mule, 9 Seeker, 2 Fury, 12 Condor, 12 Gazelle
--> Transport assets total: 17.131.584.848
--> RCT total so far: 24.429.251.417
2 Monolith, 4 Star Lord, 5 Invader, 2 Merchant
--> JumpShips total: 12.344.353.363
--> Final RCT Total: 36.773.604.780 C-Bills
+ Infantry regiments (excluding light/heavy vehicles, but including trucks etc.) & pure support vehicles
