Agreed, so far then im thinking a standard infantry platoon would be something like:
Inf 15cm - 5+ 5+ LMG 15cm AP5+
and a HMG support platoon:
Inf 15cm - 5+ 6+ HMG 30cm AP5+
(reduced the CC to factor in less troops, and tripod mounted MG's are not the best thing for CC)
Mortar platoons would have indirect fire and BP's the bigger the mortar the more BP's, same with Arty just simply better range and more BP's
AT platoons
Inf 10cm - 6+ 6+ ATG 30cm AP5+/AT5+
(reduce or increase range and AT value depending on gun)
Carriers/halftracks - in effect as rhinos, maybe tweak the stats to add an LMG
Tanks would need statting up, though I think I would stat them in classes of light/medium/hvy/ super hvy for ease rather than looking into the capabilities of each type, and for now I'd go with the no save in CC for AV unless RA
Air, its not something I use regularly so not overly sure if this would stand as is or need amending, a few plane types would need statting up though
better inf ie para's/airborne some SS etc would have better FF & CC, some would have multiple ranged shots
Need to think about formations, though at a platoon per stand, battalion looks about right, Initiative as IG in the main with maybe some exceptions such as armies wholly made up of elites - para battalions for eg.
im just rambling now
so will see what you guys can add
