Which type of patrol is primarily focused on engaging or destroying the enemy?

The focus of a combat patrol is indeed on engaging or destroying the enemy. This type of patrol is primarily designed to conduct offensive operations, seeking to locate and engage enemy forces directly. They carry out missions intended to disrupt, damage, or destroy enemy units or installations, making them distinct from other types of patrols that tend more towards observation, security, or support roles.

In contrast, reconnaissance patrols are aimed at gathering intelligence about the enemy's activities, positions, and strengths without necessarily engaging them. Security patrols are primarily focused on protecting a specific area, unit, or asset from enemy threats, instead of engaging directly. Support patrols are designed to assist other units, providing logistical or combat support without being primarily offensive in nature. Thus, combat patrols are specifically structured and trained for direct confrontation with the enemy, making them the correct choice for this question.
