Which of the following is NOT a tactical mission task?

The term "Reconquer" is not classified as a tactical mission task within the context of infantry operations. Tactical mission tasks are specific actions that platoons and squads perform to support the overall objectives and include actions such as suppressing enemy forces, seizing terrain or objectives, and destroying enemy capabilities.

"Suppress" refers to actions that limit the enemy's ability to operate and can involve direct or indirect fire to reduce their effectiveness. "Seize" entails taking control of a specific area or objective, ensuring that friendly forces can operate effectively in that space. "Destroy" involves targeting and neutralizing enemy capabilities to degrade their operational effectiveness.

These terms reflect established categories of mission tasks that units are trained to execute within various operational environments. In contrast, "Reconquer" suggests a broader strategic goal rather than a specific tactical action, which is why it does not fit into the standard set of tactical mission tasks recognized in ATP 3-21.8.
