The Haganah used the force as a "Training Centre" and put as many of its members through the JSP as possible: 13,455 between its formation and the end of 1945.[1] The British authorities provided special uniforms, guns, light trucks and some machine guns and allowed the force to control sections of land around Jewish villages and Kibbutzim.[10] The JSP also provided paramilitary training to Haganah units.[11] The force thus expanded the assets of the Haganah and helped to provide a legal basis for much of their activities.[12][13][14]
