  1-51. The role of ADA forces spans the full range of operations and is a critical enabler in the Army’s ability
  to execute its tasks. ADA forces support Army, joint, and multinational forces in the execution of offensive,
  defensive, stability, and defense support of civil authorities operations. They facilitate the conduct of decisive
  and sustainable land operations by Army and other land forces. As with joint operations, the tasks may vary
  by type of operation and across the strategic, operational, and tactical levels of war. However, irrespective of
  type operation, ADA forces fundamentally defend friendly forces and other designated critical assets and
  engage and destroy air and missile threats, ranging from ICBMs to RAM munitions.
  1-52. ADA key tasks in support of the defense include:
  * Providing AMD coverage of designated critical assets.
  * Providing and disseminating early warning to all affected forces.
  * Providing situational awareness of the airspace.
  * Contributing to engagement information (classification, discrimination, and identification).
  * Determining, predicting, and reporting enemy air and missile launch points and impact points.
  * Proactively engaging threat air and missile platforms before they attack or surveil.
  * Integrating joint and multinational capabilities into the defense design.
  1-53. ADA is a key enabler to forces conducting offensive operations. ADA tasks include:
  * Providing AMD coverage of maneuver forces and their critical assets, to include denying
  surveillance by threat air platforms.
  * Developing targeting information in support of attack operations.
  * Defending forward-based infrastructure, such as lines of communications and command nodes,
  from air and missile attacks.
  * Determining, predicting, and reporting threat air and missile launch points and projected impact
  points.
  * Providing early warning and surveillance.
  1-54. ADA key tasks in support of stability operations include:
  * Providing forward deployed or forward stationed ADA forces to serve as flexible deterrent
  options. This is a prelude to unified land operations and serves as an initial condition for shaping
  operations.
  * Supporting security assistance and building partnership capacity efforts through training,
  education, participation in exercises, and related activities with multinational AMD forces.
  * Providing AMD protection for deployed forces and civilian assets and areas from aerial threats,
  such as RAM attacks.
  * Providing or supporting Army-common tasks related to essential governmental services,
  emergency infrastructure reconstruction, and humanitarian relief efforts.
  1-55. ADA key tasks in defense support of civilian authority operations focus on:
  * Providing sensor surveillance in support of civilian law enforcement agencies – primarily to U.S.
  Customs and Border Protection organizations along the U.S. borders. ADA sensors are ideally
  suited to provide surveillance support to counter-drug operations. Sentinel radars can detect and
  track low-flying aircraft approaching and penetrating the border.
  * Deploying sensors (for example, Sentinel) in support of National security special events and
  special event assessment rating events, such as the Olympics and Super Bowl.
  * Planning for transition to active defense capabilities when properly directed and authorized.
  1-56. Fulfilling the ADA role hinges on the ability of ADA forces to conduct effective C2 across both
  engagement operations and force operations. Engagement operations are functions and activities required
  to execute the air, missile, and counter-surveillance battle. Force operations are actions and functions
  required to plan, coordinate, prepare for and sustain the total air and missile defense mission. See
  paragraphs 2-3 (on page 2-2) through 2-24 (on page 2-6) for additional discussion of force operations and
  paragraphs 2-25 (on page 2-7) through 2-38 (on page 2-10) for engagement operations.
