  Example LRSU Operational Employment--ISR Task Force
  Operational areas can be assigned, or remain unassigned, and thus the responsibility of the higher
  headquarters such as the division or corps. When the higher headquarters leaves areas unassigned, that
  portion of the AO requires a level of situational understanding (SU) sufficient to detect and classify threats.
  During past operations, an intelligence, surveillance and reconnaissance (ISR) task force, successfully
  provided SU to the division or corps headquarters in an unassigned AO (Figure 1-2).
  Figure 1-2. Concept of intelligence, surveillance, and reconnaissance.
  A key enabler of future warfighting concepts is enhanced situational awareness (SA) that leads to actionable
  SU. This is achieved by fusing information obtained through a layered network of Soldiers, sensors, and
  collection platforms with information on friendly forces, enemy forces, and the environment to obtain a common
  operational picture that is shared across the force. The ISR task force integrated multiple intelligence-gathering
  systems and provided information about the enemy or potential enemy to the decision maker.
  The most successful use of the ISR Task Force concept and organization has occurred during stability
  operations, due to the relative freedom of movement available to both friendly and enemy forces. The enemy
  force often hides among the population, making them difficult to track and target. The ISR Task Force
  integrated many sources to create actionable intelligence.
  LRSU have typically been integrated into the ISR Task Force to provide combat information through persistent
  surveillance on named areas of interest (NAIs) or targets. In addition to providing combat information, the
  LRSU clandestinely emplaced, monitored, and recovered sensors for other units attached to the ISR Task
  Force. The LRSU also acquired targets for artillery and close air support (CAS), and interdicted targets as part
  of (sniper) operations against selected targets.
  The BFSB is similar to an ISR Task Force in that it is organized to integrate intelligence, R&S and other
  combat units to provide immediate response to actionable intelligence. The BFBS headquarters element is
  sufficiently robust that it can accept attachment of combat forces.
