Despite their defeat in World War I, the German officer corps in the interwar period still saw the main means of victory in a future war in an offensive operation. Thus, he drew a different experience from the Great War than his French counterpart. Based on the experience of 1914-1918, including the infiltration tactics used by the Stosstruppen troops, but also noticing the intense development of aviation and armored weapons, part of the German officer corps (e.g. Gen. Heinz Guderian) developed theoretical assumptions of the so-called lightning war (German: Blitzkrieg), that is, striving to knock down the enemy with one decisive offensive operation carried out in the shortest possible time and with the maximum intensity of forces and resources. The German officer corps was also trained according to this offensive doctrine of war in the 1930s and during the world war. It is also worth adding that German officers of almost all levels in the course of World War II used the principle of the so-called command by task (Ger. Auftragstaktik), that is, they outlined to their subordinates the task to be achieved and the forces at their disposal, while the execution of the task was entirely up to them. Such a model of command, based on very well and uniformly trained officers, led to the fact that the German army was highly flexible in action and was able to react faster to various levels than its opponents (e.g. the French army during the campaign of 1940 or Soviet army of 1941). This system proved successful (especially at lower levels) throughout World War II. It is also worth adding that many outstanding commanders served in the German officer corps from the Second World War, including: Erich von Manstein, Heinz Guderian, Erwin Rommel and Walter Model.
Afrika Korps (full German name: Deutsches Afrikakorps, abbreviated as DAK) is colloquially understood as the collective name of German land units fighting in North Africa in 1941-1943. The Afrika Korps was formed in February 1941, as a result of the painful defeats suffered by the Italian army during the battles with the British in Africa at the turn of 1940/1941. His main task was to come to the aid of the Italian ally and stop the advance of British troops in Libya. The commander of the unit was a general, and later a field marshal, Erwin Rommel. Initially, the DAK consisted of only the 5th Light Division (later transformed into the 21st Armored Division), in May 1941 it was joined by the 15th Armored Division, and at the end of 1941 - the 90th Light Division. It is worth adding that already in the middle of 1941 the Panzergruppe Afrika was founded, headed by Erwin Rommel, and it was joined by Afrika Korps. Despite the defensive tasks, the DAK (or more broadly the Panzergruppe Afrika) very quickly after landing - on the initiative of its commander - went into strictly offensive operations, inflicting a series of defeats in the desert on the British in 1941-1942. However, it was then that its commander was nicknamed the Desert Fox. At the same time, however, from the very beginning, DAK was troubled by supply problems, which had a negative impact on its ability to conduct offensive actions. He suffered a significant defeat during the Second Battle of El Alamein (October-November 1942), which forced the DAK to retreat as far as Tunisia, in which he fought until May 1943.
