What is the last mandatory element of the call for fire?

The last mandatory element of the call for fire is the target description. This component is critical because it provides the necessary information to the delivering unit about what is being engaged. A clear and accurate target description helps ensure that the supporting unit can identify the target and apply the right level of force while minimizing the risk of fratricide or collateral damage.

By detailing characteristics such as the nature of the target, its activity, and any distinguishing features, the requesting unit enhances the chances of successful engagement. This final piece of information encapsulates the call, bringing together the details that have been communicated previously, such as location and size, into a coherent picture of the target.

The other elements, while necessary for clarity and effectiveness, are not necessary as the last piece of the call for fire. For instance, while target size is important for determining how much munitions might be required, it is not the concluding mandatory element. Similarly, specifying the location helps ensure the supporting unit knows where to aim, and the ammunition type could guide how to engage the target, but these do not serve as the final clarifying detail essential to complete the communication of the target’s identity.
