On December 24, 1979, the Soviet Union invades Afghanistan, under the pretext of upholding the Soviet-Afghan Friendship Treaty of 1978.
As midnight approached, the Soviets organized a massive military airlift into Kabul, involving an estimated 280 transport aircraft and three divisions of almost 8,500 men each. Within a few days, the Soviets had secured Kabul, deploying a special assault unit against Tajberg Palace. Elements of the Afghan army loyal to Hafizullah Amin put up a fierce, but brief resistance.
