Causes of withdrawal

Some of the causes of the Soviet Union's withdrawal from Afghanistan leading to the Afghanistan regime's eventual defeat include[183]

The Soviet Army of 1980 was trained and equipped for large scale, conventional warfare in Central Europe against a similar opponent, i.e. it used armored and motor-rifle formations. This was notably ineffective against small scale guerrilla groups using hit-and-run tactics in the rough terrain of Afghanistan. The large Red Army formations weren't mobile enough to engage small groups of Muj fighters that easily merged back into the terrain.[183] The set strategy also meant that troops were discouraged from "tactical initiative", essential in counter insurgency, because it "tended to upset operational timing".[184]
The Russians used large scale offensives against Mujahideen strongholds, such as in the Panjshir Valley, which temporarily clearing those sectors and killed many civilians in addition to enemy combatants. The biggest shortcoming here was the fact that once the Russians did engage the enemy in force, they failed to hold the ground by withdrawing once their operation was completed. The killing of civilians further alienated the population from the Soviets, with bad long-term effects.[183]
The Soviets didn't have enough men to fight a counter-insurgency war (COIN),[184] and their troops were not motivated. The peak number of Soviet troops during the war was 115,000. The bulk of these troops were conscripts, which led to poor combat performance in their Motor-Rifle Formations. However, the Russians did have their elite infantry units, such as the famed Spetsnaz, the VDV, and their recon infantry. The problem with their elite units was not combat effectiveness, but the fact that there were not enough of them and that they were employed incorrectly.[183]
Intelligence gathering, essential for successful COIN, was inadequate. The Soviets over-relied on less-than-accurate aerial recon and radio intercepts rather than their recon infantry and special forces. Although their special forces and recon infantry units performed very well in combat against the Mujahideen, they would have better served in intelligence gathering.[183]
The concept of a "war of national liberation" against a Soviet-sponsored "revolutionary" regime was so alien to the Soviet dogma, the leadership could not "come to grips" with it. This led to, among other things, a suppression by the Soviet media for several years of the truth how bad the war was going, which caused a backlash when it was unable to hide it further.[184]

Aftermath
Weakening of the Soviet Union

According to at least scholars Rafael Reuveny and Aseem Prakash, the war contributed to the fall of the Soviet Union by undermining the image of the Red Army as invincible, undermining Soviet legitimacy, and by creating new forms of political participation.

The war created a cleavage between the party and the military in the Soviet Union where the efficacy of using the Soviet military to maintain the USSR's overseas interests was now put in doubt. In the non-Russian republics, those interested in independence were emboldened by the army's defeat. In Russia the war created cleavage between the party and the military, changing the perceptions of leaders about the ability to put down anti-Soviet resistance militarily (as it had in Czechoslovakia in 1968, Hungary in 1956, and East Germany in 1953). As the war was viewed as "a Russian war fought by non Russians against Afghans", outside of Russia it undermined the legitimacy of the Soviet Union as a trans-national political union. The war created new forms of political participation, in the form of new civil organizations of war veterans (Afghansti) which weakened the political hegemony of the communist party. It also started the transformation of the press/media which continued under glasnost.[49]
Of the troops deployed, 53,753 were wounded, injured, or sustained concussion and 415,932 fell sick. A high proportion of casualties were those who fell ill. This was because of local climatic and sanitary conditions, which were such that acute infections spread rapidly among the troops. There were 115,308 cases of infectious hepatitis, 31,080 of typhoid fever, and 140,665 of other diseases. Of the 11,654 who were discharged from the army after being wounded, maimed, or contracting serious diseases, 10,751 men, were left disabled.[179]

Material losses were as follows:[20]

451 aircraft (includes 333 helicopters)
147 tanks
1,314 IFV/APCs
433 artillery guns and mortars
11,369 cargo and fuel tanker trucks.
