  Communications Nets
  2-214. C2 of OPFOR organizations relies on extensive and redundant com-
  munications. The OPFOR primarily uses UHF/SHF SATCOM, radio relay
  multichannel, HF radio stations, HF and VHF single-channel radios, and
  wire or cable. In modernized OPFOR units, the command, operations, intelli-
  gence, and logistics nets may operate over a digital network of linked com-
  puters, obviating the need for voice communications.
  2-215. The OSC operates two command nets. The commander normally con-
  trols the primary command net from the forward CP, while the chief of staff
  maintains control of the alternate net from the main CP. Depending on the
  distances involved, the primary net may be either HF or VHF. All of the
  command’s constituent and dedicated units monitor the command nets. The
  IFC CP also monitors the command nets
  2-216. The operations officer maintains an operations net monitored by
  the commander, subordinate and supporting units, and any alternate or
  auxiliary CP created. The resources officer also monitors this net from the
  sustainment CP.
  2-217. The DC, as IFC commander, maintains the integrated fires net. This
  net is monitored by the subordinates of the IFC and RISTA assets assigned
  IFC missions.
  2-218. The resources officer maintains the support net. The OSC’s materiel
  support, maintenance, and medical units monitor this net. Subordinate com-
  bat arms units may also use this net when requiring additional, immediate
  assistance that constituent support assets are unable to provide.
  2-219. The chief of reconnaissance maintains an intelligence net, monitored
  by reconnaissance units, maneuver units, the commander, DC, chief of staff,
  and resources officer.
  2-220. The CAO maintains the airspace control net for the purpose of control-
  ling the command’s airspace. Organizations on this net include aviation
  units, air defense assets, and army aviation and Air Force liaison teams.
  2-221. When required, the commander can create a special mission net,
  monitored by the chief of staff, that is employed to control the activities of
  units conducting a special mission, such as a reconnaissance detachment or
  an airborne or heliborne landing force deployed behind enemy lines. Specific
  communications systems employed are dependent on the depth and type of
  mission.
  2-222. The chief of force protection maintains an air defense and NBC warn-
  ing communications net, monitored by all constituent, dedicated, and sup-
  porting units. This net is used for passing tactical alerts or NBC and air
  warning reports. The chief of staff maintains a watch on the OSC-level warning
  nets at the main CP; he then disseminates warning where appropriate.
  2-223. The command establishes multichannel links between the main and
  sustainment CPs and the CPs of subordinate units. These links are used for
  high-capacity voice and data transmissions. The OSC also establishes
  multichannel links between the main and sustainment CPs.
