communications, including communications security, and intercept
operations;* it served as a kind of staff, an advisor and controller, for the
service branches that largely operated the communications and intercept
networks for the Army, Navy, and Air Force, much as the O.K.W. itself
advised and directed the service commands.
Under the Chef W.N.V. came the Amtsgruppe W.N.V. Its chief was
Major General Fritz Thiele, 48, a close colleague of Fellgiebel's who had
previously headed the O.K.H. communications and intercept
organization. He became Chef, Amtsgruppe W.N.V. the day the war
began. The unit comprised radio and wire branches, which maintained
communications between the headquarters of the three armed forces
high commands, a technical equipment office, an administrative office,
and the Chiffrierabteilung ("Cipher Office"), usually abbreviated "Chi."
