The Soviet-Afghan War was an armed conflict fought primarily between the Mujahideen against Soviet Unionball who intervened on behalf of DR Afghanistanball. The war began in 1979 when Soviet troops landed in DR Afghanistanball and quickly took over the government, urban centers, cities, communication lines, and other vital positions while preparing for incursions into the rural countryside where the Mujahideen was hiding out. The Mujahideen was pushed to the mountains and was backed into a corner, but they waged a successful guerrilla war that strained Sovietball greatly and depleted too many of its economic resources as the war dragged on.
Since this was during the Cold War, USAball and UKball got involved in the war and supplied the Mujahideen against Sovietball and the Communist DR Afghan government and later, Pakistanball and Saudi Arabiaball got involved for Pan-Islamic cooperation. Chinaball also got involved and supported Maoist groups in Afghanistan. By 1986, Sovietball had outgrown its economy and planned for a withdraw from Afghanistan which began in 1987 and was accomplished in 1989. DR Afghanball was left to fight alone and collapsed by 1992.
Due to the similar conditions, situations and outcome of the war, the Soviet-Afghan War is known as Russiaball's version of the Vietnam War and the war's end saw the rise of Al-Qaedaball and the start of the War on Terror and current War in Afghanistan.
