Organisation
The Committee for State Security was a militarised organisation adhering to military discipline and regulations. Its operational personnel held army style ranks, except for the maritime branch of the Border troops, which held navy style ranks. The KGB consisted of two main components - organs and troops. The organs included the services directly involved in the committee's main roles - intelligence, counter-intelligence, military counter-intelligence etc. The troops included military units within the KGB's structure, completely separate from the Soviet armed forces - the Border Troops, the Governmental Signals Troops (which in addition to providing communications between the central government and the lower administrative levels, also provided the communications between the General Staff and the military districts), the Special Service Troops (which provided EW, ELINT, SIGINT and cryptography) as well as the Spetsnaz of the KGB (the Kremlin Regiment, Alpha Group, Vympel, etc.).
