  COMPANY OPERATIONS BASE
  6-29. When space allows, the BRS should be physically located with or in close proximity to the COB
  TOC. This allows a direct link between the operations cell and the BRS operators. If circumstances
  prohibit this employment, the BRS is linked to the TOC by VHF, UHF TACSAT, tactical LAN, or field
  wire. A new BRS configuration is in development.
  ALTERNATE OPERATIONS BASE
  6-30. This base relays communications between the LRS teams and the COB BRS. It links to the COB
  through joint or Army tactical switching systems.
  • The COB and AOB use HF and UHF TACSAT radios as secondary means of communication.
  • Message traffic between the two stations should travel by the fastest, most secure means
  available.
  • Due to variables such as terrain and interference, the AOB can sometimes receive messages the
  COB cannot.
  • The AOB BRS is normally positioned farther from the deployed teams than the COB BRS and
  can operate mounted or dismounted. It is prepared to assume the mission if the COB, if the
  COB displaces or is destroyed.
  • The communications platoon leader recommends to the LRSC commander the approximate
  distance and location of the AOB based on, among other factors--
  -- Probability of communications with the deployed teams and the COB BRS.
  -- Available local support or unit capability to support.
  HF OR UHF TACSAT RADIO
  6-31. These are the surveillance team’s primary means of communication with the BRS. Data-burst
  equipment and compression software shorten transmission times. Encryption prevents the enemy from
  deciphering radio transmissions. Lightweight digital photo or video systems allow transmission of near
  real-time imagery.
  • The team leader selects a communication site using METT-TC. The site should allow antenna
  construction and terrain masking.
  • Teams transmit and receive routine messages during scheduled communication windows. For
  messages requiring transmission outside the schedule, the team first establishes a link with the
  COB or AOB in ALE mode or with the guard frequency, if in single sideband (SSB mode), and
  then transmits the message.
  • Internal team communications is via secure VHF radios and visual signals. Leaders ensure
  everyone takes the proper OPSEC and COMSEC precautions.
  SITE SELECTION
  6-32. The reliability of radio communications depends largely on proper radio site selection. The
  communications platoon leader and the BRS team leader must ensure that both primary and alternate sites
  satisfy technical, tactical, security, and other performance criteria.
  ALL OPERATIONS BASES
  6-33. The site needs good cover and concealment, and a location free of interference (man-made or
  natural). Moving the site may be necessary if interference becomes a problem. Common sources of
  interference include; high-tension power lines, over population of antennas, electronic countermeasures,
  thick vegetation and terrain.
