What kind of martial arts was used in the movie taken?
In my opinion, I think the character, since he was an ex-spy, Used a combination of techniques or as you call it styles from krav maga and pekiti tersia or empty hand doce pares or it could also be F.S.C. All I know is that spies are trained in a lot of combat skills to improve themselves.In my opinion, I think the character, since he was an ex-spy, Used a combination of techniques or as you call it styles from krav maga and pekiti tersia or empty hand doce pares or it could also be F.S.C. All I know is that spies are trained in a lot of combat skills to improve themselvesA lot of the techniques he uses were not exactly realistic but most of the more realistic techniques can be found in the system originally taught to WWII British and American spies. Col. Rex Applegate originally trained OSS operatives in this system during WWII, and it was used by CIA spies/assassins up through Vietnam. After Vietnam, the government determined that the system was too brutal and left it behind in favor of the more sport based system that our military and CIA currently use .
