2-256. The primary difference between a deliberate operation and hasty operation is the extent of planning and preparation the attacking force conducts. At one end of the continuum, an Infantry unit launches hasty operation as a continuation of an engagement that exploits a combat power advantage and preempts enemy actions. At the other end of the continuum, an Infantry unit conducts a deliberate operation from a reserve position or AA with detailed knowledge of the enemy, a task organization designed specifically for attacking, and a fully rehearsed plan. Most attacks fall somewhere between the two extremes.

2-257. A deliberate operation normally is conducted when enemy positions are too strong to be overcome by a hasty operation. It is a fully synchronized operation employing every available asset against the enemy defense, and are characterized by a high volume of planned fires, use of major supporting attacks, forward positioning of the resources needed to maintain momentum, and operations throughout the depth of enemy positions. Deliberate operations follow a preparatory period that includes planning, reconnaissance, coordination, positioning of follow-on forces and reserves, preparation of troops and equipment, rehearsals, and operational refinement.

2-258. A hasty operation is conducted during movement to contact, as part of a defense, or when the enemy is in a vulnerable position and can be defeated quickly with available resources. This type of operation may cause the attacking force to lose a degree of synchronization. To minimize this risk, the leader maximizes use of standard formations and well-rehearsed, thoroughly understood battle drills and SOPs. A hasty operation often is the preferred option during continuous operations, enabling the leader to maintain momentum while denying the enemy time for defense preparations.
