No video can describe the hell thrown to the Japanese (courtesy of the Red Army) [:D] Imagine an utter veteran army (after fighting the Wehrmacht for 5 years) with their hardened and scary Guards Rifle Corps, Tank Armies (with tank and mechanized corps, filled with REAL tanks), Katiushas, artillery and breakthough divisions... vs... er the mighty Japanese Tankette [:D][:D]
The poor things were simply sliced...
At least the Soviets kept their word. They had said at both Yalta and Postdam that they would attack the Japanese 2 or 3 months after the defeat of Germany (as Roosevelt had requested). June, july, august = 3 months.
From everything I have read, they broke through traditionally entrenched Japanese positions with spirit and gusto (in fact, iirc, in some places they achieved a higher artillery density than the Berlin operation). But they did take very heavy losses. Again, iirc, the authors I have read pointed to the Japanese tenacity, refusal to surrender and use of "irregular" tactics. As such, then, I think this movie should be seen as offering a somewhat accurate representation, in my opinion.
I generally find Japanese movies to be very fair to both sides of the story, if a bit melodramatic and probably amateurish from a moviemaking perspective (on which I have no opinion other than as a viewer). In contrast, I dont think I could say the same about either US or Russian films in their bulk. Many do a fairly good job presenting their own side's story but dont do so well with the enemy.
