Professor Vicente Junior
Professor Vicente JuniorCombat Instructor / Brazilian Jiu-Jitsu World Champion
Ground-fighting tactics is one of the most under-emphasized components of defensive and offensive tactics programs today. However, almost every “real” fight ends up with at least one combatant on the ground and more people are studying Brazilian Jiu-Jitsu and other ground fighting systems than ever before! That’s where Professor Vicente Junior comes in.

“VJ” is a World Champion and 4x Pan-American Brazilian Jiu-Jitsu Champion specializing in both gi (with the traditional uniform) and no-gi combat. He is a certified 3rd Degree BJJ Black Belt under the infamous Master Ricardo de la Riva.

Vicente is TCI’s secret weapon when it comes to the principles of effective ground fighting. Although he is not a police officer, he has studied our craft and has worked with tactical and special operators of TCI to train officers and special forces operators throughout America and Brazil. Vicente Junior has helped revolutionize our program.

No DT/OT program is complete without an effective ground-fighting system. Thanks to VJ, ours is one of the most advanced tactical ground fighting systems in the world.
