In the Call for Fire, what is the first piece of information required?

In a Call for Fire, the first piece of information required is the Observer ID. This identification is crucial because it establishes who is requesting the fire support, allowing communication and accountability throughout the process. The Observer ID ensures that the fire support team knows whom they are working with, which is essential for coordinating efforts and verifying the request’s legitimacy.

Establishing the observer's identity first facilitates proper communication channels and confirms that the request for artillery or other indirect fire is made by a qualified individual. Other details, such as target description and location, follow but cannot effectively be processed without establishing who is making the request. The proper sequence in a Call for Fire emphasizes clarity and safety, which the Observer ID underpins.
