Russia, to my recollection, had one man in each boarder province, a large stack of Inf, I think the majority if its inf, in Leningrad, and then another in Viborg, with a tank-mech reserve force in Belarus. It also had some modest inf stacks in the south.
Germany had 7 transports next to west Germany with more then enough inf and artillery to load – the sea lion fiegn. It also had some inf, say 5-6 strong, in Finland, east Poland and in Romania with I think 6 tanks in support of Poland and 3-4 in supp of Romania and some artillery and mech. Italy had 2 tanks and 2 mech in east Poland. Germany also had 4 tac and 4 fighters and bomber all in range of USSR.
It3 opened up Baltics, G4 German blitzed to Leningrad and used transport to land some 14 men and guns. Germany also moved into all the boarder provinces with Inf and attacked Viborg from Finland. The southern german forces moved forward one space.
USSR response was to attack Leningrad with everything in range, which was the entirety of its tanks and local inf stacks, which if I recall gave them a slight numerical advantage. USSR won, but the result was devastating for USSR. This army was smashed G5, with Germany using its transports to bring in new units and inf in Baltics. By G5 the USSR managed to pull together a large force in Bryansk from local units and from Russian reinforcements in an attempt to put together a defense.
On It4, Italy’s small force attacked from Baltic to Western Ukraine knocking out a blocking inf. G5 Germany blitzed through an empty Belarus into Bryansk with tank reinforcements in Baltics brought up from east Germany. Germany also attacked with southern Tanks and mech force from Bessarabia through Italian hole in Western Ukraine in Bryansk. Germany smashed the last major Russian force and its air force stationed there. USSR could only reinforce Moscow with infantry and was defeated.
