This is wonderful stuff, thanks for posting. Looking forward to getting home and giving it a proper look.
I've been thinking for a while about doing something battalion scale for FPW, er, in part so I can use the various lovely ranges that have come out (Perry, EoE).
Ideally I would like rules that capture the fire vs shock tactical choice at battalion level. How many men to feed into the firing line, how many to hold back formed up.
