A軍集団
For the offensive, the "Oberkommando der Wehrmacht" (German High Command) gave Army Group A the most powerful concentration of German armour and motorised forces. Although Army Group B was allocated 808 tanks, over of the total German tanks, they were largely light tanks such as the Panzer I and Panzer II, as opposed to the Panzer III and Panzer IV. The heavier tanks were handed over to Army Group A as it required the best machines to conduct the critical operation at Sedan. Army Group A contained 1,753 tanks of the heavier types.
