Progressive Fighting Systems (PFS) is an
organization dedicated to teaching realistic self defense and promoting the
expansion of Jeet Kune Do and the Filipino Martial Arts.The organization and
a system of combat thought up by Paul Vunak, who had been Dan Inosanto's
student who had been Bruce Lee's main student.
Inside the techniques included in this system
of combat are bitting (actually not used because of the danger of getting
infected) striking with the head, and fighting on the ground
The PFS is considered a system much efficient in street combats, giving
priority to the blows with head, blows with knee, to the trapping and to
techniques as the Straight Blast. These techniques form the base of that
what is the RAT program, the system of combat taught to the American special
forces, as the Navy Seal, developped by Vunak to request of that units.
Vunak has always claimed that the JKD doesn't teach better techniques, but
develops a combat efficient and better features. The goal is flow from one
technique to other and from one art to other, till when the range or the
situation doesn't change, demanding an other technique, or maybe of an other
martial art. A special quality of the PFS is also the usage of safety
equipment because of the trainings which are called crash test with test of
aggressions in full contact.
