What must be indicated in the Aviation/SOF gunship call for fire if "danger close" has been announced?

When "danger close" is announced in an Aviation/SOF gunship call for fire, it is crucial to include the Ground Commander's Initials. This signifies that the Ground Commander has authorized the engagement of targets close to friendly forces and acknowledges the associated risks. The initials provide verification and accountability, ensuring that the commander is aware of the situation and has exercised the appropriate level of command authority to proceed with the fire mission. This step is a vital portion of the communication chain, especially in high-stakes scenarios involving potential friendly fire incidents.

The other elements, while important in the context of call for fire, do not directly pertain to the unique circumstances imposed by a "danger close" announcement. The focus on the Ground Commander's Initials ensures that command oversight is maintained in potentially hazardous engagements.
