What you can do is eliminate the units, then noncom into newly captured territory.
This isn’t a blitz.
By holding mechs and tanks back during combat movement, you could potentially noncom them into zones (newly captured or not) they could not have reached during combat. you often need all your firepower so this isnt all that common but it is helpful
Ive seen it tried many times against me, but its a side show. you need a combination of events. You need to make a thousand cuts against an enemy and it will die quickly. Keep hitting France, Karelia, Italy, Benulux, Norway and you will win
The cost structure and transport rules from 42.2 are the same as the global game, so if you ever want to transition to the global, 42.2 would be a closer match, though there are many more diplomatic rules, the carrier unit is very different in global (16 cost attack 0 defend 2 2 hits) We found it for $42.
sadly the game we were playing was a KGF game. Germany is just too strong, but I do like the first round take buy to keep Germany from stacking in Karelia R1.
