  information via voice and data means. Communications modes necessary to support this mission include
  the SINCGARS for voice and EPLRS for data and position reporting.
  TACTICAL OPERATIONS INTERFACE
  8-61. Headquarters at all levels have access to the JNN to pass command and control information
  throughout the AO. The appropriate automation section is responsible for coordinating this connectivity
  and for the maintenance of the node server, when required. Transfer of data from dispersed FM units to its
  next higher level occurs via the tactical network, when capabilities permit.
  COMMUNICATIONS SECURITY
  8-62. Security of FM information is a high priority; safeguarding information is the responsibility of all
  FM personnel. Most electronic information systems and information networks are interconnected.
  Passwords and system protocols are highly valuable pieces of information that, if in the wrong hands, can
  cause the compromise of entire systems. Commanders must implement information security and
  communications security (COMSEC) policies and procedures to prevent hostile forces from accessing
  systems via the Internet or other means. FM systems are also subject to virus and worm infections.
  Commanders must ensure that proper measures are in place to protect against this threat. Personnel
  engaged in preparing and transmitting messages, whether by telephone, radio, or messenger, must know
  and comply with all COMSEC procedures. COMSEC measures include physical, cryptographic, and
  transmission security. These procedures are included in AR 25-2, Information Assurance.
  SIGNAL OPERATING INSTRUCTIONS (SOI)
  8-63. FM units currently operate the simple key loader, AN/PYQ-10, receiving necessary SOI extracts
  from their parent headquarters. These extracts include information on major supported units in the AO.
  COMMUNICATION NETWORKS
  8-64. A communication network is an organization of stations capable of directly communicating with
  other users on a common frequency or channel. FM units communicate with each other primarily on the
  FM operations network. FM units may enter supported units’ networks, such as the following:
  * Command network.
  * Operations and intelligence network.
  * Administrative network.
  COMMAND NETWORK
  8-65. The commander uses the command network for tactical control. Types of messages commonly
  passed over this network include orders, coordination, and information of immediate value.
  OPERATIONS AND INTELLIGENCE NETWORK
  8-66. Commanders and operations sections use the operations and intelligence network for command and
  control purposes. This network is used to control operations and pass intelligence information within
  commands. The network control station is located at higher headquarters. FMSTs use this network when
  deployed from the parent FM Detachments. Unit automation sections disseminate specific procedures for
  use of this network.
  ADMINISTRATIVE NETWORK
  8-67. The administrative network is used for personnel matters and for supply information and
  requirements. Battalion or brigade manpower and personnel staff officers, S-4s, and battalion or brigade
  signal staff officers at all levels of command use this network.
