Banzai charge

term used by the Allied forces to refer to Japanese human wave attacks

A Banzai charge (or "banzai attack") (萬歳突撃) was a tactic used by Japanese soldiers against the American soldiers when they were losing World War II. Banzai charges were usually suicide charges. This was so they would have an honourable death without surrender. Also, the charges were a final attempt to gain success against the Allied forces, which usually had more troops.
