Final answer:
Integration, as defined in FM 7-22, is the process of combining different elements of a military force to ensure they function efficiently and effectively as a single unit.
Step-by-step explanation:
According to FM 7-22, integration refers to the process by which a commander systematically combines different elements of the force to ensure they function together efficiently and effectively. This concept focuses on the idea that diverse units within an army, each with unique capabilities and purposes, must be blended and harmonized to operate cohesively as one unit. This is analogous to the way a team sport integrates players with different skills and roles to create a successful team. Integration in this context is critical for achieving strategic objectives and ensuring operational success in military operations.
