Which of the following is NOT considered a method for achieving responsive fires?

Streamlining the call for fire is an essential method for achieving responsive fires. This process simplifies and expedites how fire support requests are communicated and processed, which enhances the timeliness of response. By reducing complexity and potential delays in the call for fire procedure, the efficiency of how quickly assets can be brought to bear on a target is increased.

In contrast, increasing the number of transmissions, while it may seem useful, can create confusion and delay in communication. More transmissions can lead to information overload, making it harder for the receiving party to filter important details in real-time. Using pre-planned targets allows for quicker engagement as these targets have already been identified and coordinated, enabling faster deployment of fire support. Finally, maintaining clear communication is vital; effective and clear communication ensures that all parties involved understand the situation and can act accordingly without unnecessary delay.

Hence, while all methods mentioned facilitate responsive fires, streamlining the call for fire is a critical and widely recognized technique.
