Chapter 6 6-2 ATP 2-33.4 18 August 2014 terrain on friendly maneuver. Intelligence requirements generally associated with offensive operations are—  Determine what type of defense the enemy is employing.  Determine location, disposition, and orientation of enemy defense.  Determine enemy commander’s end state, objectives, decision points, and centers of gravity.  Determine enemy commander’s intent.  Identify terrain and weather that supports enemy defensive operations.  Identify terrain and weather that supports friendly movement and maneuver.  Determine the impact of civil considerations and displaced civilians on friendly and enemy operations.  Identify the enemy’s disruption zone, to include counterreconnaissance forces, artillery, and electronic warfare assets.  Identify the enemy battle zone.  Identify the enemy support zone, to include logistics and administrative elements, counterattack forces, and reserve forces. ANALYTIC SUPPORT TO DEFENSIVE OPERATIONS 6-5. A defensive task is a task conducted to defeat an enemy attack, gain time, economize forces, and develop conditions favorable for offensive or stability tasks (ADRP 3-0). Defensive operations retain decisive terrain or deny the enemy access to a vital area, attrite or fix the enemy as a prelude to offensive operations, counter a surprise action by the enemy, or increase the enemy’s vulnerability by forcing the enemy to concentrate his forces. (See ADRP 3-90). 6-6. The principal difference between defensive operations and other decisive action is the focus and degree of detail of analysis required for determining the enemy’s offensive framework and the effects of terrain on friendly defensive operations. Intelligence requirements generally associated with defensive operations are—  Determine, locate, and/or track the enemy’s main and supporting efforts and likely enemy avenues of approach and mobility corridors.  Locate and/or track enemy reserves.  Locate and/or track enemy reconnaissance assets.  Identify enemy’s use of special munitions.  Locate and/or track enemy close air support.  Identify enemy deception operations.  Determine enemy commander’s end state, objectives, decision points, and centers of gravity.  Determine enemy commander’s intent.  Identify defensible terrain.  Determine the impact of civil considerations and displaced civilians on friendly and enemy operations. 6-7. Offensive operations are either force oriented or terrain oriented. Force-oriented operations focus on the threat. Terrain-oriented operations focus on seizing and retaining control of the terrain and facilities. Detailed IPB products, such as a modified combined obstacle overlay with intervisibility lines or an event template, must be developed. (See FM 2-01.3 and FM 3-55 for more information on conducting IPB, information collection, and the role of all-source in defensive operations.) 6-8. Analysts are involved in all aspects of the military decisionmaking process and IPB. Several analytic techniques support activities and information requirements associated with defensive operations. ANALYTIC SUPPORT TO STABILITY OPERATIONS 6-9. Stability operations is an overarching term encompassing various military missions, tasks, and activities conducted outside the United States in coordination with other instruments of national power to
