What is the primary goal of a 'Block' tactical mission?

The primary goal of a 'Block' tactical mission is to prevent enemy access to designated areas. This involves establishing a presence in specific locations to thwart an enemy's movement or supply routes, effectively controlling the terrain and restricting their operations. By blocking or interdicting enemy forces, the mission aims to disrupt their plans, provide security to friendly forces, and maintain control over critical areas.

In the context of military strategy, such missions are essential for shaping the battlefield by denying the enemy the ability to maneuver freely, thereby allowing friendly forces to either consolidate their position, prepare for subsequent operations, or even prepare for an offensive action with reduced enemy pressure. The other options, while they describe important tactical actions, do not align directly with the unique objectives of a 'Block' mission, which focuses specifically on denial rather than capture, advancement, or retreat.
