Both German and Japanese soldiers fought in absolute atrocious conditions, conditions that many soldiers in the armies of today would mutiny over. This is most likely due to ideology and general toughness. The Germans had to protect Europe from Communism that was their drive.
The Japanese I'm not too sure on, the pacific theatre is something I'm not too knowledgeable on. I don't want to quote history channel rubbish because I only use reliable sources.
What was the Japanese motivation that achieved such bravery in the battlefield?
