The Dirlewanger Brigade, named after its commander Oskar Dirlewanger, consisted of convicted criminals who were not expected to survive their service with the unit. During its operations, the unit participated in the mass murder of civilians and in other war crimes in German-occupied Eastern Europe. It gained a reputation among Wehrmacht and Waffen-SS officers for its brutality. After troops entered a makeshift military hospital, they first killed the wounded with bayonets and rifle butts before gang raping the women. The naked bleeding nurses were then taken outside and hanged by their feet and shot in their stomachs. u/[deleted]

The shit the Nazis did to Belarus. They piled entire towns into churches and lit them on fire. They wiped out entire populations in hundreds of towns. They would also allow children to leave the church, seemingly sparing them, then they'd mow them down later after hearing their families screaming. u/Wazzoo1

Germany used prostitutes as bio-weapons. Under their rule, any prostitutes who had STIs were imprisoned so they couldn't infect German troops. As Germany started to lose ground in occupied Europe, they would release all of the women in hopes of infecting allied troops. u/No-Patient1365

Something you never hear about is what happened to displaced persons, or DP. Over 40 million people couldn’t go back to where they originally lived. A lot of people were prevented from going back. A lot didn’t want to go back. It’s a fascinating story that doesn’t get much coverage. u/emma7734

Japanese officers would test their swords on captured American airmen. A veteran I knew personally wrote about some friends who went missing after their B-25 was shot down on a strafing mission. Later, it was revealed they were used as bayonet practice after capture. When they learned their fate, they asked to be shot instead. Each man was bayonetted by a member of the Japanese infantry squad, for a total around 25 times. Other men were beheaded. u/Kishkumen7734

The shit the Japanese were doing in China (not just Nanking) even made SS officers look away in horror. To this day the Japanese government refuses to admit it ever happened, and most Japanese people were never taught about it in school. Sino-Japanese relations are still soured by that. u/ChronoLegion2

The world’s nations didn’t want their Jews back, they had already moved into their houses & businesses after all. The murder of Jews continued well after WWII ended & Germany fell. This is one of the biggest factors leading to 40% of Israel’s Jews having European ancestry. u/Nerdiedaddie
