Perhaps the major contribution of the more serious Afghan Arab volunteers was humanitarian aid —- the setting up of hospitals around Peshawar and Quetta and providing funds for supply caravans to travel to the interior of the country. Abdullah Anas, himself one of the most famous of these Afghan-Arabs fighters, said that "90 percent were teachers, cooks, accountants, doctors the border in Pakistan." The effectiveness of the Afghan Arabs in Afghanistan as a fighting force has been scoffed at, called a "curious sideshow to the real fighting," Estimates are there were about 2000 Arab Afghans fighting "at any one time", compared with about a 250,000 Afghan fighters and 125,000 Soviet troops.
