Clint Sporman began his training in Combatives in 1992, under Carl Cestari.
Carl Cestari was internationally recognized as one of the World’s foremost authorities on authentic WWII Close-Quarters Combat. Cestari’s system was based greatly on the methods taught by William E. Fairbairn & Eric A. Sykes, as well as his own personal experience.
Sporman continued intensive systematic training in all aspects of Close-Quarters Combat for the next fourteen years until Cestari’s untimely passing in 2007.
Prior to his passing, Mr. Cestari designated Clint Sporman his sole protégé and his official successor.
Alongside Cestari, Sporman interviewed and received direct training from a wide variety of noted specialists in WWII Combatives which include:
Close-Combat Instructor to OSS & MITC (Interviewed)
