Most of the earlier and recent studies on the German occupation of Greece during World War II focused mainly on military action, war crimes and mass violence, from persecution, arrests, torture, and concentration camps, to extermination. Although these studies have identified and highlighted a significant part of the German forces, there are still some dark areas in the related history. In practice, in terms of the total presence of occupation troops stationed in Greece during the war, the precisely located units represent only a fraction of the total numbers. Other military units are mainly characterized as “German units”, “German troops”, “German authorities” etc. However, the impact of these unknown units on the daily life of the Greek population was often just as important, for example through the requisition of houses and foodstuff, the imposition of forced labour, and other arbitrary measures.
