Bokator, known formally as Labokator, is a Khmer material art form that involves close hand-to-hand combat, ground techniques, and weapons. Bokator is one of the earliest Khmer material art and second in age only to the Mon-Khmer style of Yuthakun Khom. Moreover, this martial art is said to be the close quarter combat system used by the armies during the Angkor era. Practitioners are trained to strike with knees, elbows, hands feet, and even the head. Short sticks are commonly used as a weapon.
