Russia DID NOT invade Afghanistan, point one where you need to educate yourself on
Yes, Russia didn't invade Afghanistan, the Soviet Union did:
1979: Soviet invasion
On October 31, 1979 Soviet informants to the Afghan Armed Forces who were under orders from the inner circle of advisors under Soviet premier Brezhnev, relayed information for them to undergo maintenance cycles for their tanks and other crucial equipment. Meanwhile, telecommunications links to areas outside of Kabul were severed, isolating the capital. With a deteriorating security situation, large numbers of Soviet airborne forces joined stationed ground troops and began to land in Kabul on December 25. Simultaneously, Amin moved the offices of the president to the Tajbeg Palace, believing this location to be more secure from possible threats. According to Colonel General Tukharinov and Merimsky, Amin was fully informed of the military movements, having requested Soviet military assistance to northern Afghanistan on December 17.[49][50] His brother and General Dmitry Chiangov met with the commander of the 40th Army before Soviet troops entered the country, to work out initial routes and locations for Soviet troops.[49]
On December 27, 1979, 700 Soviet troops dressed in Afghan uniforms, including KGB and GRU special force officers from the Alpha Group and Zenith Group, occupied major governmental, military and media buildings in Kabul, including their primary target - the Tajbeg Presidential Palace.
That operation began at 19:00 hr., when the Soviet Zenith Group destroyed Kabul's communications hub, paralyzing Afghan military command. At 19:15, the assault on Tajbeg Palace began; as planned, president Hafizullah Amin was killed. Simultaneously, other objectives were occupied (e.g. the Ministry of Interior at 19:15). The operation was fully complete by the morning of December 28, 1979.
The Soviet military command at Termez, Uzbek SSR, announced on Radio Kabul that Afghanistan had been liberated from Amin's rule. According to the Soviet Politburo they were complying with the 1978 Treaty of Friendship, Cooperation and Good Neighborliness and Amin had been "executed by a tribunal for his crimes" by the Afghan Revolutionary Central Committee. That committee then elected as head of government former Deputy Prime Minister Babrak Karmal, who had been demoted to the relatively insignificant post of ambassador to Czechoslovakia following the Khalq takeover, and that it had requested Soviet military assistance.[51]
Soviet ground forces, under the command of Marshal Sergei Sokolov, entered Afghanistan from the north on December 27. In the morning, the 103rd Guards 'Vitebsk' Airborne Division landed at the airport at Bagram and the deployment of Soviet troops in Afghanistan was underway. The force that entered Afghanistan, in addition to the 103rd Guards Airborne Division, was under command of the 40th Army and consisted of the 108th and 5th Guards Motor Rifle Divisions, the 860th Separate Motor Rifle Regiment, the 56th Separate Airborne Assault Brigade, the 36th Mixed Air Corps. Later on the 201st and 58th Motor Rifle Divisions also entered the country, along with other smaller units.[52] In all, the initial Soviet force was around 1,800 tanks, 80,000 soldiers and 2,000 AFVs. In the second week alone, Soviet aircraft had made a total of 4,000 flights into Kabul.[53] With the arrival of the two later divisions, the total Soviet force rose to over 100,000 personnel.
March 1980-April 1985: Soviet offensives
The war now developed into a new pattern: the Soviets occupied the cities and main axis of communication, while the mujahideen, (which the Soviet Army soldiers called 'Dushman')[59] divided into small groups, waged a guerrilla war. Almost 80 percent of the country escaped government control.[60] Soviet troops were deployed in strategic areas in the northeast, especially along the road from Termez to Kabul. In the west, a strong Soviet presence was maintained to counter Iranian influence. Incidentally, special Soviet units would have[clarification needed] also performed secret attacks on Iranian territory to destroy suspected mujahideen bases, and their helicopters then got engaged in shootings with Iranian jets .[61] Conversely, some regions such as Nuristan, in the northeast, and Hazarajat, in the central mountains of Afghanistan, were virtually untouched by the fighting, and lived in almost complete independence.
Periodically the Soviet Army undertook multi-divisional offensives into mujahideen-controlled areas. Between 1980 and 1985, nine offensives were launched into the strategically important Panjshir Valley, but government control of the area did not improve.[62] Heavy fighting also occurred in the provinces neighbouring Pakistan, where cities and government outposts were constantly under siege by the mujahideen. Massive Soviet operations would regularly break these sieges, but the mujahideen would return as soon as the coast was clear.[63] In the west and south, fighting was more sporadic, except in the cities of Herat and Kandahar, that were always partly controlled by the resistance.[64]
The Soviets did not, at first, foresee taking on such an active role in fighting the rebels and attempted to play down their role there as giving light assistance to the Afghan army. However, the arrival of the Soviets had the opposite effect as it incensed instead of pacified the people, causing the mujahideen to gain in strength and numbers.[65] Originally the Soviets thought that their forces would strengthen the backbone of the Afghan army and provide assistance by securing major cities, lines of communication and transportation.[66] The Afghan army forces had a high desertion rate and were loathe to fight, especially since the Soviet forces pushed them into infantry roles while they manned the armored vehicles and artillery. The main reason though that the Afghan soldiers were so ineffective was their lack of morale as many of them were not truly loyal to the communist government but simply collecting a paycheck. Once it became apparent that the Soviets would have to get their hands dirty, they followed three main strategies aimed at quelling the uprising.[67] Intimidation/genocide was the first strategy, in which the Soviets would use airborne attacks as well as armored ground attacks to destroy villages, livestock and crops in trouble areas. The Soviets would bomb villages that were near sites of guerilla attacks on Soviet convoys or known to support resistance groups. Local peoples were forced to either flee their homes or die as daily Soviet attacks made it impossible to live in these areas. By forcing the people of Afghanistan to flee their homes, the Soviets hoped to deprive the guerillas of resources and safe havens. The second strategy consisted of subversion which entailed sending spies to join resistance groups and report information as well as bribing local tribes or guerilla leaders into ceasing operations. Finally, the Soviets used military forays into contested territories in an effort to root out the guerillas and limit their options. Classic search and destroy operations were implemented using Mil Mi-24 helicopter gunships that would provide cover for ground forces in armored vehicles.
To complement their brute force approach to weeding out the insurgency, the Soviets used KHAD (Afghan secret police) to gather intelligence, infiltrate the mujahideen, spread false information, bribe tribal militias into fighting and organize a government militia. While it is impossible to know exactly how successful the KHAD was in infiltrating mujahideen groups, it is thought that they succeeded in penetrating a good many resistance groups based in Afghanistan, Pakistan and Iran.[68] KHAD is thought to have had particular success in igniting internal rivalries and political divisions amongst the resistance groups, rendering some of them completely useless because of infighting.[69] The KHAD had some success in securing tribal loyalties but many of these relationships were fickle and temporary. Often KHAD secured neutrality agreements rather than committed political alignment.[70] The Sarandoy, a KHAD controlled government militia, had mixed success in the war. Large salaries and proper weapons attracted a good number of recruits to the cause, even if they were not necessarily "pro-communist". The problem was that many of the recruits they attracted were in fact mujahideen who would join up to procure arms, ammunition and money while also gathering information about forthcoming military operations.[69]
On his arrival in power in March 1985, the new Soviet General Secretary Mikhail Gorbachev expressed his impatience with the Afghan conflict. He demanded that a solution be found before a one-year deadline. As a result, the size of the LCOSF (Limited Contingent of Soviet Forces) was increased to 108,800 and fighting increased throughout the country, making 1985 the bloodiest year of the war. However, despite suffering heavily, the mujahideen were able to remain in the field and continue resisting the Soviets.
