Which term describes the immediate indirect and joint fires provided to neutralize enemy indirect fire weapons once acquired?

The term that best describes the immediate indirect and joint fires provided to neutralize enemy indirect fire weapons once acquired is "Reactive Counterfire." Reactive counterfire specifically involves the rapid response to identified threats from enemy indirect fire assets, such as mortars or artillery. This form of fire support aims to quickly mitigate the risk posed by these threats, ensuring that friendly forces remain protected from incoming artillery fire.

Reactive counterfire is often utilized in situations where the enemy's indirect fire capabilities have been detected, enabling friendly forces to respond effectively with their own indirect fire assets. This concept emphasizes the importance of timely and accurate targeting to neutralize the enemy's ability to deliver effective fire.

In contrast, aggressive counterfire generally involves a more proactive approach of seeking out and destroying enemy indirect fire assets before they can be used, while point defense focuses on protecting specific assets or locations from enemy attack. Counter-battery fire, while related, typically refers to targeting enemy artillery in a broader sense rather than the immediate response context indicated by reactive counterfire.
