Jujitsu

Jujitsu, meaning the "way of yielding", was a name for Japanese martial art styles consisting of grappling and striking techniques. Jujutsu evolved among the samurai of Japan as a method for dispatching an armed and armored opponent in situations where the use of weapons was impractical or forbidden. These techniques were developed around the principle of using an attacker's energy against him, rather than directly opposing it, and came to be known as jujutsu.

Roberta Lincoln was quite adept at jujitsu by 1974.
