What action is outlined for the support force during a breach operation?

In a breach operation, the primary focus for the support force is the elimination of enemy capabilities. This action is crucial as it ensures that the main attacking force can breach enemy defenses without excessive interference from hostile units. By neutralizing enemy threats, the support force creates a more favorable environment for the attacking troops, enabling them to advance and secure the area effectively.

While additional actions such as conducting ground assessments for safety, identifying safe exit routes, and establishing communication links are also important and play significant roles in the overall operation, they are not the central focus of the support force's immediate responsibilities during a breach. The elimination of enemy capabilities directly contributes to the success of the breach by reducing the risks faced by the primary assault units and maintaining momentum in the operation.
