 To complement their brute force approach to weeding out the insurgency, the Soviets used KHAD (Afghan secret police) to gather intelligence, infiltrate the mujahideen, spread false information, bribe tribal militias into fighting and organize a government militia.While it is impossible to know exactly how successful the KHAD was in infiltrating mujahideen groups, it is thought that they succeeded in penetrating a good many resistance groups based in Afghanistan, Pakistan and Iran.KHAD is thought to have had particular success in igniting internal rivalries and political divisions amongst the resistance groups, rendering some of them completely useless because of infighting.
