As a minimum, they render the volume and accuracy of the enemy's fire ineffective. Leaders look for vulnerable flanks, gaps in lines, or lulls in enemy fire. When they cannot readily find a weakness, they create one wit h suppressive fire and the surprise effect of its suddenly coming from an unexpected direction. Leaders must exploit this weakness by moving to the best covered and concealed position and then assaulting to destroy, defeat, or capture the enemy. Finally, platoons and squads must quickly consolidate the position to defend it against an enemy counterattack.
Units then reorganize themselves and prepare to continue the mission.
Leaders use graphic control measures to regulate or direct the platoon's movement, positions, and fire. Leaders use control measures to clarify their intent, focus the platoon or squad effort, and ensure synchronization. Each control measure should have a specific purpose that contributes to mission accomplishment. If a control measure fails the purpose test, leaders should not use it. Control measures can be drawn on a map, overlay, sketch, or a terrain model.
