The BRUIN communication system was an an essential element 
    in the operational structure of the British Army of the Rhine between 1967 
    and 1985. It represented a major change from conventional combat net radio 
    communication policy and paved the way for secure area trunk systems such 
    as PTARMIGAN, its successor. This article explains the history and role of 
    the BRUIN communication system and describes its facilities, its configuration 
    and the equipment used.
