What is a synchronized combined arms activity under the control of the maneuver commander to allow maneuver through an obstacle?

A synchronized combined arms activity under the control of the maneuver commander that facilitates movement through an obstacle is called a breach. This operation is specifically designed to enable friendly forces to move through a barrier, such as a minefield or enemy fortification, while minimizing exposure to enemy fire and maximizing the effective use of combined arms support.

In a breach, various elements of combat power are effectively coordinated, including infantry, armor, engineers, and aviation assets, to create and exploit a gap in enemy defenses. The maneuver commander plays a crucial role in planning and directing these operations to ensure that all components work together seamlessly. This not only involves physical destruction of the obstacle but also covers information operations, electronic warfare, and close support, all integrated to ensure a successful breach.

The other options represent different types of military operations that do not specifically focus on overcoming an obstacle in the same manner. For instance, an assault typically refers to an attack on a defended position rather than the act of maneuvering through an obstacle, while clearing usually refers to the removal of obstacles or enemies from a designated area rather than the specific operational focus of breaching. Advance relates more to the forward movement of forces rather than the tactical execution of overcoming fortified barriers.
