Combat Hapkido, also known in Korean as Chon-Tu Kwan Hapkido
(전투관 합기도), is an eclectic modern Hapkido system founded by GM John Pellegrini in 1990. Taking the next step in 1992 GM Pellegrini formed the International Combat Hapkido Federation (ICHF) as the official governing body of Combat Hapkido. In 1999, the ICHF was recognized by the Korea Kido Association and the World Kido Federation, collectively known as the Kido Hae, as the Hapkido style Chon Tu Kwan Hapkido.
Combat Hapkido is also referred to as the "Science of Self-Defense" and, according to GM Pellegrini, Combat Hapkido is a new interpretation and application of a selected body of Hapkido techniques. The word "Combat" was added to Hapkido to distinguish this system from Traditional Hapkido styles and to identify its focus as Self-Defence.
Combat Hapkido employs joint locks, pressure points, throws, hand strikes, and low-lying kicks, and trains practitioners to either counter or preemptively strike an imminent attack to defend one's self. In common with many Hapkido styles, it also emphasizes small circular motion, non-resisting movements, and control of an opponent through force redirection and varied movement. Practitioners also seek to gain advantage through footwork, distraction strikes and body positioning to employ leverage.
