Although there was no essential change in the organisation of the field units of Germany Army Sigint Service from 1941 to 1944, additional units were put in place in the field. In 1942, the eastern KONA units (1,2,3) were supplemented by the addition of KONA 6, which was formed to cover the German campaign in the Caucasus. The KONA unit was not subordinated to any Army Group but was directly under HLS Ost. KONA 7 was established in February 1943 and was subordinated to the Commander-in-Chief South, Albert Kesselring, who controlled Army Group C, and the German forces in Italy.
