   Defensive plan
   Escape routes.
   Cover.
   Concealment.
  B-62. Operating against a peer threat may require locating the signal site away from the supported command
  post. This way, if an enemy locates and destroys communications systems, they do not destroy the entire
  command post capability. Operating signal systems away from the supported command post creates
  additional physical security and site defense requirements.
  RECONNAISSANCE
  B-63. Before occupying a signal site, leaders should reconnoiter the designated area. The site reconnaissance
  might find unanticipated conditions that make the selected site unacceptable. This would require adjusting
  the operation plan or order to select a new signal site. The reconnaissance team should consist of the company
  leader, the transmission supervisor (if applicable), node supervisor (if applicable), and a security team. The
  makeup of the reconnaissance team depends on the type of unit. The reconnaissance team maintains single-
  channel radio communications with their parent headquarters. The reconnaissance team should—
  * Ensure the selected site can support the unit’s communications requirements.
  * Ensure the site is large enough to accommodate and tactically disperse all communications
  assemblages on the site.
  * Determine whether the selected site is securable and defensible. The reconnaissance team
  considers—
   The size of the site.
   The number of personnel available to defend the site.
   Entrances and avenues of approach.
   Concealment from major roads or other vantage points. This may involve traveling around
  the entire site from a distance to visualize what the enemy would see.
  * Verify the site is close enough to the supported unit command post to connect with the signal
  systems. Increasing distance between signal assemblages and subscribers complicates
  troubleshooting.
  * Verify line of sight between stations for multichannel radio links. Line of sight planning range is
  about 40 kilometers, or 28 miles.
  * Ensure terrain and man-made structures will not interfere with communications equipment and
  links.
  SIGNAL SITE SECURITY AND DEFENSE
  B-64. Site defense plans depend on the size and type of signal site and whether it is colocated with the
  supported unit. Planners coordinate with the G-2 (S-2) staff for the current threat estimate and the G-3 (S-3)
  staff for security force requirements when planning site defense.
  Colocated Sites
  B-65. Usually, these are larger signal elements, up to platoon size, supporting a unit command post. The
  signal personnel assist in perimeter defense. The supported unit headquarters conducts the overall defense of
  the command post. The signal element coordinates closely with the supported unit.
  Remote Sites
  B-66. Planners must coordinate for security and sustainment services when deploying signal sites remotely
  from the supported unit. When a signal site does not colocate with the supported headquarters, the signal
  element conducts site defense. They must also be prepared to survive enemy air, artillery, and chemical,
  biological, radiological, and nuclear attack with little outside assistance. Because of their size and limited
