Why were the Afghans successful against the Soviet Union's invasion in 1979?

Answered below

Explanation:

The Soviet-Afghan war was a guerilla ear fought by the insurgent groups called the Mujahedeen, against the Soviet army and the government of Afghanistan throughout the 1980s. The conflict occurred in the Afghanistan countryside. The insurgent groups were supported by Saudi Arabia, the United Kingdom, the United States, and Pakistan.

This massive support was key to their success in the war against the Soviet Union. The war quickly settled into a stalemate, with the Soviet army controlling the cities and towns and the insurgents controlling the countryside.

The Mujahedeen were able to neutralise the Soviet air power by the use of shoulder-fired anti-aircraft missiles and weapons supplied by the United States.

The Soviet Union later signed an accord with the United States, Pakistan and Afghanistan and agreed to withdraw it's troops from the region. The withdrawal was completed in 1989.
