text: Fighting for Intelligence During Large-Scale Combat Operations
  8-114. Commanders, G-2/S-2s, and other staffs collaborate through several means, including video
  teleconference meetings, to create a common understanding of the enemy and to ensure the information
  collection plan addresses changes in the situation. The collection emphasis message is used between echelons
  to share important aspects of information collection and collection transitions before staffs can complete the
  entire information collection plan. Intelligence handover lines are also useful in collaborating between
  echelons and with adjacent units when the timely tracking of a specific enemy force is necessary.
  8-115. In many situations, commanders and staffs can use intelligence handover lines to focus collection
  on HPTs. Intelligence handover refers to the transfer of information collection and intelligence analysis on
  an enemy force or capability between two echelons or units. The purpose is to maintain continuous contact
  with an enemy force or capability and gain an understanding of that force or capability in relation to the
  terrain and current situation. Intelligence handover occurs as a graphic control measure known as an
  intelligence handover line; however, a unit can use another type of control measure.
  8-116. During intelligence handover, the initial unit (the unit first making contact) and the gaining unit
  share responsibility until the handover is complete or the mission is changed. When possible, the collection
  management team at the initial unit includes the intelligence handover line with specific details (such as
  handover guidance and operational and technical parameters as part of coordinating instructions) within
  Annex L (Information Collection) and shares the annex with the gaining and adjacent units. If the intelligence
  handover line is developed and coordinated during ongoing operations and Annex L (Information Collection)
  is not updated, the initial unit must share intelligence handover specific details in a collection emphasis
  message, or other means, especially when the intelligence handover involves ground reconnaissance.
  8-117. When establishing intelligence handover lines, units can use existing graphic control measures. For
  example, the fire support coordination line (also called FSCL) can be used as an intelligence handover line
  between corps and divisions and the coordinated fire line between divisions and subordinate units. Using this
  practice simplifies intelligence handovers and is also effective in linking sensors to shooters. It also enables
  divisions to thoroughly nest their priorities with corps’ priorities. Using an intelligence handover line also
  prevents redundancy of collection efforts while maintaining continuity of intelligence operations. However,
  there is utility for units to collect beyond the fire support coordination line as this can assist them in shaping
  future engagements. For example, information collection beyond the fire support coordination line may be
  necessary to plan for and employ capabilities to achieve favorable force ratios before the division engages
  enemy forces.
  Information Collection Collaboration Examples
  The corps G-2 anticipates that an enemy unit designated as an HPT will cross a key phase
  line in the next 24 to 48 hours. The predicted movement of the HPT causes the corps G-3
  and G-2 to coordinate with the division G-3 and G-2 to ensure continuous tracking of the HPT
  with no loss of coverage. During the intelligence synchronization meeting, the corps G-2 and
  the division G-2 coordinate an intelligence handover line to ensure continuous coverage of
  the HPT. Another information collection technique is coordinating for complementary or
  supporting coverage. For example, the theater army conducts UAS collection for the corps
  while the HPT moves to an intelligence handover line where the corps then tracks the HPT
  to a deep engagement area and conducts BDA.
  Phased and Continuous Information Collection
  8-118. A phased and continuous information collection effort accounts for all phases of an operation as well
  as continued collection into a branch, sequel, or next operation. Different information collection tasks occur
  to support a specific phase or phases. The collection management and information collection plans are
  developed as part of the MDMP or RDSP. These planning processes drive the way a unit starts collection
  management and then phases into information collection.
