The Cyber and Information Domain Service (CIDS; German: Cyber- und Informationsraum, pronounced [ˈsaɪbɐ ʔʊnt ʔɪnfɔʁmaˈtsi̯oːnsʁaʊm] ⓘ; CIR) is the youngest branch of the German Armed Forces, the Bundeswehr.

[3] In November 2015, the German Ministry of Defense activated a Staff Group within the ministry tasked with developing plans for a reorganization of the Cyber, IT, military intelligence, geo-information, and operative communication units of the Bundeswehr.

[4] The CIDS Headquarters took command of all existing electronic warfare, signals, IT, military intelligence, geoinformation, and psychological operations units.
