What urban patrol principle involves positioning units to cover each other's movements?

The principle of mutual support is crucial in urban patrolling as it involves positioning units in such a way that they can provide assistance and cover for one another during operations. This is vital in complex environments where visibility and avenues of movement are often limited. By ensuring that units are strategically placed to observe and reinforce each other, they can effectively respond to threats, share intelligence, and protect their flanks.

In situations where one unit may encounter enemy fire, nearby units can provide suppressive fire or maneuver to assist without leaving the area vulnerable. This interconnectedness and reliance on each other's strengths help to create a more cohesive and effective patrolling strategy, ultimately enhancing the overall effectiveness and safety of the patrol operation. This principle is fundamentally about creating a network of security that can respond dynamically to enemy actions, ensuring that no unit operates in isolation.
