Volume IIB completes the Wehrmacht, and the German mobilisation and war-economy, in 1941. It includes the most detailed Orders of Battle ever published on the German Army (Heer), Luftwaffe and Waffen SS (across the whole Reich) in June-July 1941. Even the smallest and most obscure ground and air units are included, while the Luftwaffe OOBs include details on aircraft types and strengths. Also scrutinised are: the personnel and equipment assigned to combat-units in each army or reserve-force in all areas of the Reich, the ground and air unit reinforcements as well as those newly mobilised, the military personnel and equipment that became available in the Reich during 1941, the Replacement Army, the mobilisation process and resources used, the available replacements and those sent east, the logistical supply of the Wehrmacht (the varying Supply Distribution Efficiency), the Kriegsmarine forces in the east, and the Wehrmacht killed, wounded, missing/POW, unfit and recuperated casualties.
