  Security Fundamentals
  Provide early and accurate warning
  The ability of Apache troop and the observation posts to directly observe Iraqi tanks north of
  the screen provided situational awareness to 3-7 CAV and ultimately 1st BCT, 3rd Infantry Division.
  Provide reaction time and maneuver space
  The ability of Apache troop and the observation posts to identify a battalion of Iraqi tanks north
  of the screen provided the squadron with ample time to plan an attack while aircraft and
  artillery engaged the suspected targets.
  Orient on the force or facility to be secured
  3-7 CAV protected the flank of 1st BCT, 3rd Infantry Division, ensuring that the seizure of
  Baghdad International Airport occurred without interference. The squadron did so by
  operating between the BCT and the threat of Iraqi intervention from the north.
  Perform continuous reconnaissance
  The combination of checkpoints and the forward movement of Apache troop ensured continuous
  monitoring of the surrounding area. It was through this troop’s actions that the Iraqi tank force
  was located and destroyed.
  Maintain enemy contact
  The checkpoints provided a means of monitoring the surrounding area and maintaining contact
  once the Iraqis sought to penetrate the screen. In most cases, the troop maintained contact
  through a mix of observation posts and direct fire engagements employed through the
  squadron’s combat power mix of tanks and Bradleys. Additionally, when aircraft identified a
  tank force north of the screen, the troop maintained contact through the application of air
  strikes and artillery, followed by the dispatch of Apache troop to ascertain the impact of
  this bombardment.
  COMMANDER’S SECURITY GUIDANCE
  5-12. The BCT commander’s guidance should consist of the security focus, duration, and engagement and
  disengagement criteria. In providing this guidance, the commander describes, shapes, and prioritizes the
  intended vision of the security effort supporting the overall scheme of maneuver and the specific roles of the
  Cavalry unit. As with the commander’s reconnaissance guidance, this guidance and the importance of
  accomplishing the mission must be understood at echelon. (Refer to chapter 3 of this manual for detailed
  information about the commander’s security guidance.)
  SECTION II – COUNTERRECONNAISSANCE
  5-13. Counterreconnaissance is a tactical mission task that encompasses all measures taken by a commander
  to counter enemy reconnaissance efforts. (Refer to ADP 3-90 for more information.) The purpose of
  counterreconnaissance is to destroy, defeat, or repel all enemy reconnaissance elements within capabilities
  and following engagement criteria. Counterreconnaissance is not a distinct mission, but a component of all
  types of security operations. Counterreconnaissance denies the enemy commander the ability to conduct
  reconnaissance and develop their situational understanding. Successfully countering enemy reconnaissance
  is the first and possibly most important step to ensure the BCT can successfully execute its mission.
  5-14. Counterreconnaissance is an inherent task in all security operations. Counterreconnaissance keeps
  enemy reconnaissance forces from observing the main body by defeating or blocking them. Units organize
  to defeat enemy reconnaissance forces without requiring reinforcement. Additionally, units consider enemy
  reconnaissance capabilities to determine if additional maneuver or sustainment assets are required.
  5-15. The counterreconnaissance plan should address how to acquire and defeat enemy reconnaissance
  elements. The intelligence section provides key input into the planning process. The intelligence section
  identifies avenues of approach into the unit’s sector, which type of enemy reconnaissance elements the unit
  expects in the sector, and when they are most likely to move into the sector. The commander of the squadron
  or counterreconnaissance force uses this information to formulate the counterreconnaissance plan and to task
