Muslim rebels are resisting the invading Soviet forces.

Explanation:

The Soviets invaded Afghanistan in 1979 and fought a war against Muslim rebels and guerillas for almost 10 years. The war ended in the withdrawal and some might say, defeat of the Soviets.

As part of its Cold War antics, the United States supported the Muslim rebels with arms and money which enabled them to shoot down Soviet aircraft and harass her soldiers until the war became too costly for the Soviets and they had to withdraw.
