Did the German and Japanese soldiers actually been given drugs to make them fight fanatically during WW2?

or at any plans esp. the Germans and Japanese were involved in medical research such as the Japanese 731 units.

I don't know about the Japanese.





I understand the Germans were issued caffine pills to help them keep going.





They even portray it in the Hitchock film "Lifeboat" - though the film was created in part as propoganda.
