Brazilian Jiu-Jitsu (BJJ) has become a popular martial art and self-defense system used by law enforcement and military personnel around the world. This is due to the effectiveness of BJJ techniques in close-quarter combat situations where grappling and ground fighting techniques are required. BJJ provides an array of techniques such as throws, takedowns, joint locks, chokes, and submissions, which can be used to subdue suspects or enemies without causing severe injury or fatalities. Furthermore, BJJ training enhances situational awareness, reaction time, and critical thinking skills of law enforcement and military personnel, making them better equipped to handle potentially dangerous situations.

BJJ has also been incorporated into the training programs of various law enforcement agencies and military units, including the US Army Special Forces and Navy SEALs. The techniques learned in BJJ training have been adapted to suit the needs of the military, especially in combat situations where soldiers may need to engage in hand-to-hand combat. BJJ training teaches soldiers how to effectively defend themselves and incapacitate their enemies without using lethal force, which is critical in situations where preserving human life is of utmost importance. BJJ has also been shown to improve physical fitness, mental toughness, and resilience, all of which are important qualities for military personnel to possess.
