  * Field- and sustainment-level maintenance for organic signal equipment and automation systems.
  * Limited maintenance of special operations forces-unique signal equipment.
  * Communications support for airborne and airdrop operations.
  Rangers
  2-89. The Ranger Regiment’s organic signal company deploys worldwide to install, operate, maintain, and
  secure the regiment’s communications and automated information systems. The Ranger Regiment signal
  company establishes secure networks to support the regiment’s operations and integrate with the Army force
  component of a joint force. The signal company provides local area network support for the company, the
  Ranger battalions, the Ranger Special Troops Battalion, and the Ranger Regiment.
  2-90. The Ranger Regiment signal company provides—
  * Automated information systems support for maneuver, support, and command elements.
  * Tactical radio relay, retransmission, and beyond line of sight high frequency and single-channel
  satellite communications to extend networks.
  * Global Broadcast Service capability to receive high bandwidth imagery, logistics data, and digital
  map information to support command and control.
  * Field- and sustainment-level communications-electronics and COMSEC maintenance for the
  special troops battalion and supporting organizations.
  SUPPORT TO CYBERSPACE OPERATIONS
  2-91. Cyberspace operations are the employment of cyberspace capabilities where the primary purpose is to
  achieve objectives in or through cyberspace (JP 3-0). The core cyberspace operations missions are—
  * DODIN operations.
  * Defensive cyberspace operations.
  * Offensive cyberspace operations.
  2-92. Cyberspace actions support DODIN operations, defensive cyberspace operations, offensive cyberspace
  operations, or any combination thereof. Executing cyberspace actions at any echelon is dependent on
  authority, capability, and coordination. The cyberspace actions are interrelated. A cyberspace mission may
  require more than one action to achieve mission success. The cyberspace actions are—
  * Cyberspace defense.
  * Cyberspace intelligence, surveillance, and reconnaissance.
  * Cyberspace operational preparation of the environment.
  * Cyberspace attack.
  * Cyberspace security.
  2-93. Signal support to cyberspace operations includes the tasks to establish the baseline security posture
  and operate the DODIN-A. Signal Soldiers perform DODIN operations to support both the joint and Army
  portions of cyberspace and take part in CEMA.
  2-94. Cyberspace security actions are those taken within a protected network. Cyberspace security actions
  prevent unauthorized access to, an exploitation of, or damage to computers, electronic communications
  systems, and other information technology, including platform information technology. Cyberspace security
  actions help ensure the availability, integrity, authentication, confidentiality, and nonrepudiation of classified
  and other sensitive information. Cyberspace security is not specific to an enemy or adversary. Cyberspace
  security actions protect the networks and systems through all phases of network planning and
  implementation. Cyberspace security activities include vulnerability assessment and analysis, vulnerability
  management, incident handling, continuous monitoring, and detection and restoration capabilities to shield
  and preserve information and information systems (FM 3-12). Refer to FM 3-12 for more information about
  the other cyberspace actions.
