Tajbeg Palace assault

The Tajbeg Palace assault, known by the military codename Operation Storm-333 (Russian: Шторм-333, Štorm-333), was a military raid executed by the Soviet Union in Afghanistan on 27 December 1979. It saw Spetsnaz GRU storm the heavily fortified Tajbeg Palace in Kabul and subsequently assassinate Afghan leader Hafizullah Amin, a Khalqist of the People's Democratic Party of Afghanistan (PDPA) who had taken power in the Saur Revolution of April 1978. The Soviet military operation marked the beginning of what would later become known as the Soviet–Afghan War.

The assassination of Amin was part of a larger Soviet plan to secure and take control of Afghanistan with support from the PDPA's Parcham faction, which opposed the hardline ideology espoused by the rival Khalq faction; a number of Soviet troops crossed the Amu Darya and entered Afghanistan by land while others flew to airbases around the country with exiled Parchamis in preparation for the assassination. The Tajbeg Palace, located on a high and steep hill in Kabul, was surrounded by landmines and guarded by extraordinarily large contingents of the Afghan National Army. Nonetheless, Afghan forces suffered major losses during the Soviet operation; 30 Afghan palace guards and over 300 army guards were killed while another 150 were captured. Two of Amin's sons, an 11-year-old and a 9-year-old, died from shrapnel wounds sustained during the clashes. In the aftermath of the operation, a total of 1,700 Afghan soldiers who surrendered to Soviet forces were taken as prisoners, and the Soviets installed Babrak Karmal, the leader of the PDPA's Parcham faction, as Amin's successor.

Several other government buildings were seized from Amin's Khalqist government during the operation, including those for the Ministry of Interior Affairs, the KHAD, and the General Staff (Darul Aman Palace). Veterans of the Soviet Union's Alpha Group have stated that Operation Storm-333 was one of the most successful in the unit's history. Documents released following the dissolution of the Soviet Union in the 1990s revealed that the Soviet leadership believed Amin had secret contacts within the American embassy in Kabul and "was capable of reaching an agreement with the United States"; however, allegations of Amin colluding with the Americans have been widely discredited, with the Soviet archives revealing that the story of Amin as a CIA agent had been planted by the KGB.
