"During the 1930’s the SS (Schutz Staffel or Protection Squad) became the main paramilitary arm of the German Nazi Party. As time went on, the Waffen-SS (Armed SS) was formed as the combat arm of the SS. The Waffen-SS effectively formed a fourth arm of the military alongside the Heer (Army), Luftwaffe (Air Force) and Kriegsmarine (Navy). This article looks at the SS-Panzergrenadier divisions operating in Russia in 1942 and 1943. At the outbreak of war in 1939, the Waffen-SS fought alongside the regular army, much to the distrust of many military officers who did not feel that a political organisation had a role in battlefield operations. However, as the combat experience of Waffen-SS units grew, acceptance of their role as battle-proven units increased. By 1943 eight Waffen-SS divisions formed an experienced and battle-hardened spearhead for Germany’s armies, particularly on the Eastern Front."
