In an Immediate Suppression Polar Call for Fire (COF), what must be included besides the observer identification and warning order?

In an Immediate Suppression Polar Call for Fire (COF), it is crucial to include the target location defined by direction and distance. This information is essential for ensuring that artillery or air support can accurately target the enemy position. The observer must provide precise data on where the ordnance should be directed to effectively engage the target, which is paramount in a time-sensitive situation where rapid response is necessary.

In the context of a Polar call for fire, the observer typically communicates the target location using a polar coordinate system. This involves specifying the direction (azimuth) and the range (distance) from a known point, usually the observer's location. This method of targeting helps minimize the risk of fratricide and maximizes the effectiveness of the fire support.

Including other factors such as target area size, collateral damage assessments, or wind information is important in broader operational contexts, but for an Immediate Suppression call, the immediate requirement is to convey the exact location of the target as swiftly and accurately as possible. Such precision is vital for ensuring that the fire support can be effectively brought to bear on the intended target without delay.
