What is the term for when OPFOR has overmatch and brings all offensive combat power to bear?

The term for when OPFOR has overmatch and brings all offensive combat power to bear is "Integrated Attack." This concept emphasizes the comprehensive utilization of various forces and capabilities in a coordinated manner to achieve maximum effectiveness against the enemy. When OPFOR achieves overmatch, it indicates a significant superiority in combat power, allowing them to launch an offensive that applies combined arms approaches—utilizing infantry, armor, artillery, and air support seamlessly together.

In an Integrated Attack, the synchronization of different units enables them to overcome enemy defenses efficiently. This strategy is critical in modern combat environments where rapid maneuver and concentrated firepower can decisively change the course of an engagement.

The other terms, while related to military operations, do not capture the full scope of utilizing every element of combat power in a unified offensive action as "Integrated Attack" does. Integrated Defense focuses on fortifying positions rather than offensive maneuvers, Coordinated Attack suggests a degree of organization but lacks the specific emphasis on overmatch and total force application, and Comprehensive Assault implies a wide-ranging offensive but does not encapsulate the thorough integration of diverse combat elements.
