Yakut as starting position: it’s mainy a threat to strafe, not a full counterattack advancing to the coast (But may risk to become so if it goes ‘too well’)
1R: 10 inf 2 ftr threatens max Japanese force in Buryat which can be only 3inf 1tnk. (Assuming Kwangtung transport sunk 1UK) So they don’t try.
2R: 10 inf 2 ftr threatens max Japanese landing which can be 6inf 1arty 1tnk. So they do it one area back, in Kwangtung.
3R: cannot attack anymore, if Japan concentrate in Buryat 2 turns worth of transports. But they can still hold. 1-2 tanks may arrive to improve defense.
4R Russians have to retreat.
Novosibirsk as medium-term holding position. The unapproachable dead zones would be Yakut, Sinkiang and Kazakh. Tank reserve can be in Moscow, threatening Ukraine and Persia too.
On longer term building race: agree that 8 units/turn is only a start, and at one time Japan would NEED a factory or two.
Factory in Novosibirsk: I think it’s necessary once Japan is solid in place. Cheaper inf/arty can be built and defend right now, and attack next turn. Tanks in factories (Kwantung, FIC etc) need 3 turns from income to battle, and are relatively more expensive. Forces from Japan need 5 turns.
And for a time, the two flows cumulate: new forces built in Novo, old flow still coming for 4 more turns before being reduced (not a lot, because of the total income).
Factory in Caucasus: it’s very nice, the problem is that at this stage both sides have a stalemate of 80-100 units. If this is all, Russians still win with 6-8 units/turn built compared to Japan’s 4. What I was talking about was the smaller new force gathering in Yakut etc. from further landings. It may get to 20-30 units or so, but surely it would be suicide to put it in Novo next to the 100 unit Russian mass strafing every turn. And if waiting until second Japan army is strong enough, at that time the Russian mass may have overtaken the Caucasus besiegers. To unify back in Kazakh at the last moment would abandon the factory, and the east force needs to come from Sinkiang (since Novo is a dead zone). Right ?
So back to a simple frontal siege from Novosibirsk.
An interesting case can be made for swapping or keeping flank areas (Evenki, Kazakh, Persia etc) with more forces. Like 3-4 inf each. If Russia wants to swap them, they can do it only one at a time, and send some forces (some of them offensive, like arty) each turn. At this stage, accelerated attrition works for Japan, and they have more fighters. Or Russia may ignore Japanese presences, and the income difference helps Japan again.
