After the fall of the Shah in 1979, the Islamic Republic of Iran established the Islamic Revolutionary Guard Corps (IRGC) to domestically promote the government's social policy. IRGC is accused of spreading its ideology in neighboring regions by training and funding "terrorist organizations". By 1986, IRGC had 350,000 members and had acquired a small naval and air force. By 1996, its ground forces numbered 100,000 and the naval forces numbered 20,000. They are believed to use the Quds Force to train Islamic militants.
