Dave Mustaine is now a brown belt in jiu-jitsu. On Friday night, Oct. 7, Dave was awarded the esteemed brown belt in the sport, the highest level just below the ultimate pinnacle black belt. The brown belt typically takes five years from a beginner level to achieve and is a very competitive level to rank at. He was promoted by Reggie Almeida, who leads Gracie Barra Spring Hill BJJ & Self-Defense in Tennessee.
