Brigadier General Amir Sultan Tarar, also known by his nom de guerre Colonel Imam (4 April 1944 – 23 January 2011), was a Pakistani military officer and diplomat who served as the Consul-General of Pakistan at Herat, Afghanistan. A Pakistan Army officer and special operations specialist, he was a member of the Special Service Group (SSG), Pakistan's army special forces, and was an intelligence officer in the ISI. A veteran of the Soviet–Afghan War, he is widely believed to have played a key role in the formation of the Taliban, after having helped train the Afghan mujahideen on behalf of the United States in the 1980s.
"Colonel Imam," as Tarar was also known, was a commando-guerrilla warfare specialist, trained Mullah Omar and other Taliban factions and leaders. Colonel Imam remained active in Afghanistan's civil war until the 2001 United States led War on Terrorism, and supported the Taliban publicly through media.
