The 1.66 download has a proposed later unit balance list also.
Main highlights for those interested (changes from GK values, not VEM balance).
Boost
Tanks
Helos
MG/Gatling Defence
Lancer attack (much higher).
Slight boosts to Armor, Artillery/Cannon regular attacks, very slight to Cavalry and Arty vs city.
Nerfs
Rocket Artillery (both v city and regular, presumably from no alum requirement)
Infantry
GW Infantry
MG/Gatling Attack
AA Gun
Slight nerfs to Mech Infantry, SAMs, ATGs, Rifles, Marines, Airborne, Landship, very slight Cannon vs city.
@Thal will there be any vanguard unit between Skirmishers and Paratroops (or are Paras still vanguards)? Light Infantry is gone from the table. I gathered this was a possibility from the use of Gatling/MGs instead. This could at least suppose that a medic promotion should be available for other industrial units?
