A軍集団
Army Group A (Heeresgruppe A) was the name of several German Army Groups during World War II. During the Battle of France, the army group named Army Group A was composed of 45½ divisions, including 7 armored panzer divisions. It was responsible for breaking through the heavily-forested Ardennes region. The operation, which was part of "Fall Gelb" (Case Yellow), was resoundingly successful for the Germans, as the army group outflanked the best troops of France and its allies, eventually leading to France's surrender.
