  6-96. FA units reposition to where they can support a renewed attack. Aviation assets can provide support
  while artillery systems reposition. A commander may need to request additional resources to include
  reconnaissance, surveillance, and TA WLR assets to help identify targets for attack.
  6-97. Pursuit is a type of offensive operation designed to catch or cut off a disorganized hostile force
  attempting to escape, with the aim of destroying it (FM 3-90). A pursuit normally follows a successful
  exploitation. Unlike an exploitation, which may focus on seizing key or decisive terrain instead of the enemy
  force, the pursuit always focuses on completing the destruction of fleeing enemy forces by destroying their
  ability and will to resist. The commander in a pursuit tries to combine direct pressure against the retreating
  forces with an enveloping or encircling maneuver that fixes the enemy in positions where the enemy force
  can be defeated in detail. Fires can restrict movement of the enemy force and delay and disrupt its ability to
  quickly execute the maneuvers vital to protecting itself see figure 6-5.
  Figure 6-5. Exploitation and pursuit
  6-98. An aggressively executed pursuit keeps the moving enemy unprepared, and unable to defend,
  ultimately faced with the options of surrendering or complete destruction. Pursuits require swift maneuver
  and attacks by forces to strike the enemy's most vulnerable areas. There are two options in conducting a
  pursuit; each involves assigning a subordinate the mission of maintaining direct pressure on the rearward
  moving enemy force. The first is a frontal pursuit that employs only direct pressure. The second is a
  combination that uses a subordinate element to maintain direct-pressure and one or more other subordinate
  forces to encircle the enemy. In the pursuit, the most decisive effects result from combining a direct pressure
  force and an encircling force (FM 3- 90).
  6-99. There is generally little time to establish and affect new task organizations or support relationships
  between an attack and exploitation or pursuit. These operations transition very quickly from one to another.
