To meet this situation after the Western Campaign in 1940, companies were taken from the Army intercept service (General der Nachrichtenaufklärung), reorganised and re-equipped for security intercept work and placed under the control of WNV/FU III. They continued to carry their former intercept company numbers. Five such companies were formed, two being created initially in early 1942 from the Luftwaffe intercept service to cover the Balkans. These radio monitoring () companies formed the principal operational resources of the Funkabwher.
