3-76. Commanders change tactics, modify their exercise of command and control, change task organization, and adjust the weight placed on each element of decisive action throughout an operation. This helps to seize, retain, and exploit the initiative. Commanders base decisions on their understanding of the situation, available resources, and the force’s ability to conduct operations. Commanders assess the progress of ongoing operations, changes in the situation, and the force’s combat effectiveness. Commanders also assess how well a current operation is shaping conditions for subsequent missions.
