It is a hybrid discipline that incorporates elements of various martial arts such as various wrestling styles, judo, and Brazilian jiu-jitsu.

Submission wrestling is practiced both as a competitive sport and as a training method for self-defence and mixed martial arts (MMA).

The label is sometimes also used to describe the tactic in mixed martial arts competition of relying primarily upon submission wrestling skills to defeat an opponent.

[3] Combat Jiu-Jitsu (CJJ) is a submission grappling style innovated by American BJJ black belt Eddie Bravo in 2013.

In 2019, Keenan Cornelius, a BJJ black belt from San Diego, founded his personal academy that he named Legion American Jiu-Jitsu (AJJ).

After that, he started to explain the style to the media, which caused a backlash from the Brazilian community, although Cornelius continued promoting his academy.
