Which aspect of the attacker’s capabilities is interrupted by the defender?

The aspect of the attacker's capabilities that is interrupted by the defender is fire support and command and control. This is critical because fire support encompasses the various means by which a force can deliver firepower to support ground operations. Command and control involve the processes of directing and controlling forces to execute missions effectively.

When a defender successfully counters an attacker, it can disrupt their ability to coordinate and execute their fire support capabilities. For instance, if a defender can target the attacker's artillery or disrupt their communication systems, the attacker may struggle to effectively direct their fire support. This disruption can lead to confusion and a lack of synchronization among the attacker's units, ultimately degrading their overall effectiveness in the operation.

In modern warfare, the effectiveness of operations heavily relies on integrated command and control, where decisions are made and communicated in real time. Therefore, if a defender can impose disruptions in these areas, it significantly hampers the attacker's operational capabilities.
