WW2 SG2

Thought: all discussion hinges or rating FP wrt current weapons. Ignore that.
you won't have them on the field. A WW2 SAW is an MG42 or a Bren. D8 or D10
FP. A BAR gets FP3. An M1 FP2. etc. rate things versus the
maximums the game provides (FP 1-4, then dice, Impact d8-d12 ish) then
you'll have the "variability" needed to show the variance in weapons.
