When a patrol receives indirect fire, what report is generated?

When a patrol receives indirect fire, the appropriate report generated is a Spot Report. This type of report is crucial as it provides immediate information about the initial observations regarding the indirect fire, including details such as the location, type of fire, and any observed impact on personnel or equipment. Spot Reports are used to ensure that command and relevant units are quickly informed of significant events, enabling timely responses and resource allocation.

The other options do not align with the requirements for reporting indirect fire. A CBRN Report pertains to chemical, biological, radiological, and nuclear threats, which is not applicable in the context of indirect fire. A Shelling Report, while it might seem relevant, is typically not the designated term used within military reporting structures for the situations described. An Action Report usually focuses on actions taken by units in response to specific incidents and may not serve as the first, immediate communication needed when indirect fire is encountered. The Spot Report, therefore, serves as the essential tool for rapid communication of important event details in such scenarios.
