A commander attempts to bypass and avoid obstacles and enemy defensive positions to the maximum extent possible to maintain tempo and momentum. Breach is a tactical mission task in which the unit employs all available means to break through or secure a passage through an enemy defense, obstacle, minefield, or fortification. Breach Tactical Mission GraphicДЇigure B-4. Movement instructions to the initial battle positions. Reconnaissance, preparing and securing movement routes and firing positions before the movement of the main body, and stocking Class V items. OPSEC to deceive the enemy about movement, occupation, and intent of the operation. Providing for security and all-around defense, including control measures to ensure tie-in of subordinate elements and maximum use of hide positions. Дesignating battle positions, area of operations (AO), or axis of advance to allow the friendly force to engage the enemy.Дesignating control measures to allow massing, distributing, and shifting of direct and indirect fires.The attack by fire task includes-ДЄssigning sectors of fire or EAs to each subordinate weapon system to include the enemy's defensive positions or avenues of approach. The chief difference is that one unit conducts the support-by-fire task to support another unit so it can maneuver against the enemy. An attack by fire closely resembles the task of support by fire. The arrow points at the targeted force or objective, and the commander places the base of the arrow in the general area from which he wants to deliver the attack.Д«-4. Figure B-2 shows the tactical mission graphic for attack by fire. The commander may assign the force conducting an attack by fire a battle position with either a sector of fire or an engagement area (EA), or he may assign it an axis of advance and a force-oriented objective. A commander normally employs this task when the mission does not dictate or support close combat and occupation of a geographical objective by another friendly force. A commander assigning this task to a subordinate must also state the desired effect on the enemy, such as neutralize, fix, or disrupt. Attack-by-fire is a tactical mission task in which a commander uses direct fires, supported by indirect fires, to engage an enemy without closing with him to destroy, suppress, fix, or deceive him. Attack-by-Fire Tactical Mission GraphicД«-3. Tacticians use these graphics in conjunction with course of action development. Many of the tactical mission tasks in this appendix have a tactical mission graphic associated with them. Likewise, an attacking unit requires more combat power to clear the enemy from a given area than to contain him in that same area.Д«-2. For example, a defending unit requires far greater effort (resources) to destroy an enemy force than to defeat it. The commander ensures that the missions he assigns his subordinate units are consistent with his scheme of maneuver and the resources allocated to his subordinates. It should be noted that tasks involving only actions by friendly forces rarely provide sufficient clarity for a mission statement thus the addition of a solid purpose coupled with the task adds understanding and clarity. However, both the commander and the subordinate must have a common understanding of the what and why of the operation. Many of the words and terms used to describe the what and why of a mission statement do not have special connotations beyond their common English language meanings. The commander is not limited to the tactical mission tasks listed in this appendix in specify-ing what actions he wants from his subordinates in an OPORD or OPLAN. As shown in Figure B-1, there is no definitive list of words or terms to describe the what and the why of a mission state-ment. Tasks that identify a friendly action rarely provide sufficient clarity for a mission statement.Д«-1. In some cases, the discussion includes more than just a definition it includes results or effects in relation to the enemy, terrain, or friendly forces not associated with any specific type or form of an operation. These tasks have specific military definitions that are different from those found in a dictionary. The why of a mission statement provides the mission's purpose or reason. The what is an effect that is normally measurable. The what and why of a mission statement are not the same thing and both are needed. A mission statement contains the who, what, when, where, and why associated with a specific operation. The tactical mission tasks in this appendix describe the results or effects the commander wants to achieve-the what and why of a mission statement not previously addressed in this manual. Appendix B Tactical Mission Tasks Doctrine provides a military organization with a common philosophy, a common language, a common purpose, and a unity of effort.
