I was thinking about this sort of this yesterday based on current rules.
For standard infantry, a 4-man base looks best:
4 x FP1 = d4
4 x FP2 = d8
4 x FP3 = d12
For the support weapons, it may need a little thought about how a 2 or 3 man
base would contribute. Just the support weapon? Or support weapon +
rifles? Option for just rifles?
With an average 8-man squad of 6 FP2 rifles, SAW and PIG we would get:
4 rifles = d8
SAW+rifle = d8
PIG = d6
For a total of Q+2d8+d6, which gets towards the "bucket 'o' dice" for
company level activations, but the fine detail will make or break this part
of combat.
