USSR VS JAPAN ,what would happen in WWII

 

 

It's difficult to say depending on which time period (need to be more specific than just WWII... a lot of shits happened during that period), variables, but if you were to ignore everything else except just USSR and Japan... it would be USSR all the way probably. In Manchuria and Chinese mainland, USSR will wipe the floor against Japanese with little practical battle experience against modernized forces. Russians will emphasize the meaning of superior armor doctrine with superior armors (even for western standards) whereas Japs had little anti-tank weapons... even fewer arsenals that would effectively take out Russian medium/heavy tanks like T-34 and KV-1. Russians would enjoy numerical superiority, and their rapid-firing, short-ranged submachineguns and semi-automatic rifles would haunt Japs' WWI-era bolt-action rifles. (Type 100 did exist but unlike in real life, there were preciously few Type100 submachinegun compared to COD5). The Japanese will make Russians pay for every land they grab but as demonstrated in Eastern Front, that won't slow down Russians so much. Trans-Siberian railway would ensure that moving all Russian troops to the Far East would be feasible given enough time, but if I was a Japanese commander I'd exploit this like Chinese gold farmers ;)

The real issue is what happens after China and Korea falls. Can Russians defeat the Japanese Imperial Navy and make a touchdown on Japanese soil? Unlike Japs' crappy army, their navy was formidable. Modernized and was nearly second to none until Americans went batshit with their naval program.... we may have Operation SeaLion scenario again. Soviet air army wasn't much to brag about until they modernized and received costly battle experience against Germans. In a long run, I feel Russians will cross the Sea of Japan eventually as Japs won't be able to crunch out fighters and pilots like the Anglo-Americans did. Once Russians can convoy to Japanese heartland, it's game over. 

It's overly simplistic view, but it's mine. Screw you guys, I'm going home.
