Book excerpt: ADP 5-0 provides doctrine on the operations process. It describes fundamentals for effective planning, preparing, executing, and assessing operations. It describes how commanders, supported by their staffs, employ the operations process to understand situations, make decisions, direct action, and lead forces to mission accomplishment. To comprehend doctrine contained in ADP 5-0, readers should first understand the fundamentals of unified land operations described in ADP 3-0. As the operations process is the framework for the exercise of command and control, readers should also understand the fundamentals of command and control and mission command described in ADP 6-0. Readers must also understand how the Army ethic guides decision making throughout the operations process (see Army doctrine on the Army profession).
