The KAPAP system was developed in the late 1930s, within the Jewish Aliyah camps (ma-a-not Olim) as part of preparatory training before their arrival in the British Mandate of
Palestine. The Palmach and Haganah used KAPAP as an ongoing combat development program for their recruits.
It was primarily considered a practical skill set that was acquired during the training period of the Palmach and Haganah fighters. The main focus was to upgrade the physical endurance,
elevate and strengthen the spirit, developing a defensive and offensive skill set. It included physical training and endurance, cold weapon practical usage, boxing, judo, jujutsu, karate
and knife and stick fighting.
