How did the Russian winter affect German troops and equipment near Moscow?

The Russian winter of 1941–1942 had a devastating impact on German forces near Moscow, as the Wehrmacht had not been prepared for a winter campaign.12

Impact on Troops
German soldiers suffered immensely due to a lack of adequate winter clothing, leading to widespread cases of frostbite that decimated their ranks as early as November. Because Adolf Hitler forbade significant retreats, troops were forced to remain in exposed positions, enduring extreme suffering and exhaustion. Many divisions were reduced to a fraction of their original strength, a depletion from which they never fully recovered.132

Impact on Equipment
The severe, subzero temperatures paralyzed German mechanized transport, tanks, artillery, and aircraft. Additionally, soldiers struggled to operate frozen weapons. While the Luftwaffe attempted to maintain supply lines to isolated garrisons by air, the harsh conditions drained their operational strength. In contrast, Soviet forces were better equipped for the cold and utilized specialized tactics, such as snow camouflage, which proved highly effective against the struggling German invaders.312
