Which phase of CBRN response focuses on synchronizing planning and execution efforts with the supported civil authorities?

The correct answer is tied to the importance of coordinating and integrating actions between military and civil authorities during a CBRN (Chemical, Biological, Radiological, and Nuclear) incident. In the operational phase of a CBRN response, the focus is on executing the prepared plans effectively, which includes ensuring that the military's actions are aligned with the public safety objectives established by civil authorities. This synchronization is critical for maximizing resources, achieving a unified command, and ensuring the safety of both responders and the public.

During this phase, efforts include exchanging real-time information and integrating resources between departments to manage the incident effectively. Cooperative execution can significantly enhance the effectiveness of the overall response by leveraging both military capabilities and civil resources when dealing with the complexities of CBRN threats.

In contrast, the other phases focus more on preparation, immediate response during the incident, and the recovery aspects following the immediate operational phase, rather than the synchronization of ongoing efforts with civil authorities during an active operation.
