  targets of opportunity. Once in place, ADA forces should implement passive defense measures, such as
  camouflage and protective works, and continuously improve them as long they remain at a location.
  Deception, camouflage, and concealment should be used as much as possible to deny or limit the ability of
  enemy surveillance assets to identify sensor, shooter, and C2 components and ultimately target them.
  Emission control measures should be initiated to reduce the electromagnetic signatures of the sensors and
  command posts (CP).
  DECEPTION
  2-22. Deception operations are designed to mislead enemy decision makers by distorting, concealing, and
  falsifying friendly intentions, capabilities, and dispositions. The objective is to mislead the enemy
  commander, inducing the enemy to conduct activities that unwittingly serve friendly purposes.
  2-23. ADA units plan and conduct deception activities in conjunction with movement, cover, concealment,
  and other passive defense operations to disguise friendly capabilities and counter enemy capabilities. In the
  context of tactical deception, ADA units may position weapons systems in locations forward of those
  typically associated with a point defense. For example, Avengers, employed with Patriot in an integrated
  defense of a fixed or semi-fixed asset, are generally positioned to deny an enemy low-level access to the asset
  and to defend the Patriot system. Moving Avengers forward along likely enemy air avenues of approach
  provides early and unexpected (to the enemy) engagement opportunities. ADA units conduct deception in
  support of operations security by emission control, “blinking” sensors, and employing counter-
  countermeasure. Emission control of sensors in the defense limits sensor radiation until the last moment in
  an engagement sequence, thus reducing or denying enemy targeting. Radiating multiple sensors in a defense
  at different times and different locations hinders potential lock-on by anti-radiation missiles. Employing
  counter-countermeasure capabilities mitigates the effects of enemy jamming or other electromagnetic
  deception. See FM 3-13.4 for additional information on Army military deception operations.
  2-24. A summary of the key force operations tasks, with respect to planning and preparing for aerial
  engagements, is presented in table 2-1. The tasks are representative of those that are conducted across the
  ADA force, though not necessarily be each of the ADA echelons. See chapters 5 through 9 for additional
  discussions of force operations by each.
