ARB (martial art) in the context of "Jujutsu"

Jujutsu (Japanese: 柔術 jūjutsu, Japanese pronunciation: [dʑɯːʑɯtsɯ] or [dʑɯꜜːʑɯtsɯ] ), also known as Japanese jiu-jitsu and simply jiu-jitsu or ju-jitsu (both /dʒuːˈdʒɪtsuː/ joo-JITS-oo), is a Japanese martial art and a system of close combat that can be used in a defensive or offensive manner to kill or subdue one or more weaponless or armed and armored opponents. A subset of techniques from certain styles of jujutsu were used to develop many modern martial arts and combat sports, such as judo, aikido, sambo, Brazilian jiu-jitsu, ARB, and mixed martial arts.
