Mass rather than skill formed the basis of the Red Army’s victory primarily because inadequate training, weak motivation, and low morale plagued the army for the duration of the war, though after the Battle of Kursk, soldier motivation and morale improved. Often poorly led, inadequately fed, ill-trained, and under-supplied, Red Army soldiers faced daunting prospects just to survive. The dire need to replace losses led to abbreviated training; troops were thrown into battle with little preparation, leading combat effectiveness to suffer; fearful and feeling unprepared, soldiers deserted, shirked, straggled, and showed cowardice and committed many acts of indiscipline, crimes, and violations of regulations on a wide scale. When given the right equipment and weaponry, and properly trained to use it, and led by competent leaders, most soldiers fought well and with determination. These conditions, however, did not present themselves very often. Officers were often in positions for which they were unprepared. The ability of the Red Army to fight well improved in 1943 with defense production at full capacity and American Lend-Lease delivering vital supplies.
