Which of the following is NOT one of the three types of local missions in defense?

In military terminology, local defense missions are categorized into three main types: screen, guard, and covering force. Each of these missions serves specific strategic purposes and is crucial to the overall defense operations.

Screen missions involve providing early warning and maintaining contact with the enemy while being positioned to avoid engagement. This allows for the allocation of forces elsewhere while still gathering intelligence on enemy movements.

Guard missions focus on securing key terrain or assets against enemy advances while allowing for some level of engagement with the enemy. This mission emphasizes the preservation of these key assets and can involve both defensive and offensive actions as necessary.

Covering force missions are designed to protect withdrawing forces from enemy attack. They create a buffer by engaging the enemy and delaying their advance, allowing the main force to withdraw safely.

The term "contain" does not belong to this classification of local defense missions. While containment may be a tactical approach, it does not specifically define a mission type within the context of local defense operations. Thus, it does not fit alongside the established categories of screen, guard, and covering force.
