Which helped the Soviets stop the German advance just miles from Moscow in December 1941?

The Soviets were able to halt the German advance near Moscow in December 1941 due to several key factors. The most significant was the onset of harsh winter weather, which severely hampered German troops and their equipment, many of which were not winterized. Additionally, the Soviet Union launched a counteroffensive, mobilizing fresh troops and utilizing better knowledge of the local terrain. The combination of these elements, along with the resilience and determination of the Soviet forces, ultimately turned the tide in favor of the Soviets.
