What is a type of offensive operation that destroys or defeats enemy forces, seizes and secures terrain, or both?

The type of offensive operation that is designed to destroy or defeat enemy forces, seize and secure terrain, or accomplish both objectives is an attack. This operation is characterized by its focus on engaging the enemy to decisively inflict damage and disrupt their combat capabilities. It can be executed in various forms, including rapid maneuvers and sustained engagements, allowing the attacking force to achieve its tactical or strategic goals.

An attack is a broader concept that encompasses various specific types of operations, like the deliberate attack, which is carefully planned and executed with detailed preparations. In contrast, choices like movement to contact focus more on establishing contact with the enemy rather than directly aiming to destroy or seize terrain. Exploitation, on the other hand, comes into play after an initial success is achieved, intending to capitalize on enemy weaknesses. Understanding the distinction between these concepts highlights why the attack is the best-fit answer for this question regarding offensive operations.
