The Russians had an advantage in night fighting among the ruined buildings and factories, sometimes using just knives or grenades instead of guns. The Germans use night cover too for bloody house to house counteratacks. The intensity of night darknes in houses was sometimes terrible when enemy soldiers run to same doors (boom).
EXAMPLE: 25 Jul 1942
Sixth Army made an attempt to rush Stalingrad through the depleted 62nd Army and still deploying 64th Army (Beevor, 1999; Clark, 1965; Erickson, 1993; Fowler, 2005). For two days the Germans attacked during the day with air cover, and the Soviets counter-attacked at night. Dust storms complicated the operations.
