The standard communication format used when soliciting CAS is known as what?

The standard communication format used when soliciting Close Air Support (CAS) is known as a Close Air Support Request. This specific format is crucial for coordinating air support missions effectively, as it ensures that the necessary information is communicated clearly between ground forces and air support units. The Close Air Support Request includes details about the target, the desired effects, and the coordination measures to mitigate risks to friendly forces. It is a vital tool that facilitates quick and accurate responses to dynamic battlefield situations.

In the context of the other options, the Air Tasking Order refers to the overarching document that outlines air operations and does not serve as a direct request for CAS. The Joint Fires Observer Report is used for reporting results of joint fire missions but is not the standard format for initially soliciting CAS. The Combat Air Support Request is not a recognized term within military doctrine; the correct terminology is Close Air Support Request.
