Operation Cyclone in the context of "Afghan mujahideen"

The Soviet–Afghan War took place in Afghanistan from December 1979 to February 1989. Marking the beginning of the 46-year-long Afghan conflict, it saw the Soviet Union and the Afghan military fight against the rebelling Afghan mujahideen, aided by Pakistan. While they were backed by various countries and organizations, the majority of the mujahideen's support came from Pakistan, the United States (as part of Operation Cyclone), the United Kingdom, China, Iran, and the Arab states of the Persian Gulf, in addition to a large influx of foreign fighters known as the Afghan Arabs. American and British involvement on the side of the mujahideen escalated the Cold War, ending a short period of relaxed Soviet Union–United States relations.

Combat took place throughout the 1980s, mostly in the Afghan countryside, as most of the country's cities remained under Soviet control. The conflict resulted in the deaths of one to three million Afghans, while millions more fled from the country as refugees; most externally displaced Afghans sought refuge in Pakistan and in Iran. Between 6.5 and 11.5% of Afghanistan's population of 13.5 million people (per the 1979 census) is estimated to have been killed over the course of the Soviet–Afghan War. The decade-long confrontation between the mujahideen and the Soviet and Afghan militaries inflicted grave destruction throughout Afghanistan, and has been cited by scholars as a significant factor contributing to the dissolution of the Soviet Union in 1991; it is for this reason that the conflict is sometimes referred to as "the Soviet Union's Vietnam".

The Afghan conflict (Pashto: دافغانستان جنګونه; Dari: درگیری افغانستان) is the series of events that have kept Afghanistan in a near-continuous state of armed conflict since the 1970s. Early instability followed the collapse of the Kingdom of Afghanistan in the largely non-violent 1973 coup d'état, which deposed Afghan monarch Mohammad Zahir Shah in absentia, ending his 40-year-long reign. With the concurrent establishment of the Republic of Afghanistan, headed by Mohammad Daoud Khan, the country's relatively peaceful and stable period in modern history came to an end. However, all-out fighting did not erupt until after 1978, when the Saur Revolution violently overthrew Khan's government and established the Democratic Republic of Afghanistan. Subsequent unrest over the radical reforms that were being pushed by the then-ruling People's Democratic Party of Afghanistan (PDPA) led to unprecedented violence, prompting a large-scale pro-PDPA military intervention by the Soviet Union in 1979. In the ensuing Soviet–Afghan War, the anti-Soviet Afghan mujahideen received extensive support from Pakistan, the United States, and Saudi Arabia in a joint covert effort that was dubbed Operation Cyclone.

Although the Soviets withdrew from Afghanistan in 1989, the various mujahideen factions continued to fight against the PDPA government, which collapsed in the face of the Peshawar Accord in 1992. However, the Peshawar Accord failed to remain intact in light of the mujahideen's representatives' inability to reach an agreement on a power-sharing coalition for the new government, triggering a multi-sided civil war between them. By 1996, the Taliban, supported by Pakistan's Inter-Services Intelligence, had seized the capital city of Kabul in addition to approximately 90% of the country, while northern Afghanistan remained under the authority of the anti-Taliban Northern Alliance. During this time, the Northern Alliance's Islamic State of Afghanistan enjoyed widespread international recognition and was represented at the United Nations, as opposed to the Taliban's Islamic Emirate of Afghanistan which only received diplomatic recognition from three nations. Despite the fall of Kabul to the Taliban, the Northern Alliance continued to resist in another civil war for the next five years.

Though not officially a belligerent during the Soviet–Afghan War, the United Kingdom was heavily involved, playing a key covert role in the conflict. Also known as the Second Great Game, the British provided both indirect and direct support for the Afghan mujahideen in their fight against the Soviet Union, including secretly arming, funding and supplying various factions. Britain's Secret Intelligence Service (MI6) primarily supported the Mujahideen group Jamiat-e Islami, commanded by Ahmad Shah Massoud who, having received little support from the US and Pakistan, became Britain's key ally in the conflict. Fighting in the Panjshir valley, Massoud and his fighters with British support and intelligence, overcame nine Soviet offensives and held out up to the Soviet withdrawal from the vital valley in 1986. Massoud became the most successful and feared of the Mujahideen commanders.

The British also played a vital role in support of the US government's Operation Cyclone, from which the latter provided far more in financial and material terms. Unlike the US which had to funnel its program through Pakistan, the UK played a more direct combat role in Afghanistan itself – in particular, using retired or seconded Special forces such as the Special Air Service and private military corporations to support the resistance groups in practical manners. One of Britain's greatest contributions was training the Mujahideen; not just in Afghanistan and Pakistan but also in the Gulf states and the UK itself.

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.
