In which tactical mission does a commander aim to restrict enemy forces to a narrow area?

Canalization is a tactical mission where the commander seeks to restrict enemy forces to a narrow area. This is achieved by using terrain, obstacles, or other means to direct the enemy's movement into a constrained space. By doing this, the commander can more effectively engage the enemy, as they are funneled into a defined area where their maneuverability is limited, making them more vulnerable to attacks.

The goal of canalizing the enemy is often to enhance the effectiveness of one’s own forces, allowing them to capitalize on the concentrated enemy presence, which can lead to more decisive engagements. This tactic is particularly useful in scenarios where overwhelming force or firepower can be brought to bear on a smaller, trapped enemy force, increasing the likelihood of success in the operation.

The other options represent different tactical objectives that do not focus specifically on restricting enemy movement to a narrow area. For instance, bypassing involves moving around an enemy position, disengaging refers to breaking contact with the enemy, and destroying focuses on defeating the enemy outright. Each of these has different strategic implications and does not align with the objective of canalizing forces.
