The Soviet Union (USSR) had been a major power broker and influential mentor in Afghan politics. Its involvement ranging from civil-military infrastructure to Afghan society. Since 1947, Afghanistan had been under the influence of the Soviet government and received large amounts of aid, economic assistance, military equipment training and military hardware from the Soviet Union. Economic assistance and aid had been provided to Afghanistan as early as 1919, shortly after the Russian Revolution and when the regime was facing the Russian Civil War. Provisions were given in the form of small arms, ammunition, a few aircraft, and (according to debated Soviet sources) a million gold rubles to support the resistance during the Third Anglo-Afghan War in 1919. In 1942, the USSR again moved to strengthen the Afghan Armed Forces by providing small arms and aircraft, and establishing training centers in Tashkent (Uzbek Soviet Socialist Republic). Soviet-Afghan military cooperation began on a regular basis in 1956, and further agreements were made in the 1970s, which saw the USSR send advisers and specialists.
