In what scenario might an observer call for FFE before completing a full bracket split?

The scenario in which an observer might call for Fire for Effect (FFE) before completing a full bracket split is during a rapid engagement. This situation typically requires immediate action, as the target needs to be engaged quickly to minimize potential threats or to take advantage of a fleeting opportunity. In a rapid engagement, the urgency of the situation may outweigh the necessity for a complete bracket split, which is often executed to ensure accuracy and refine targeting based on observed impacts.

Calling for FFE directly allows for the deployment of firepower quickly rather than spending additional time on bracket splitting. This approach is particularly effective when the observer has already gathered enough information on the target's location and has confidence in the effectiveness of the engagement.

While favorable conditions, adequate PER (probability of detection), and high-pressure situations may influence decision-making, the driver for the early call for FFE remains the need for speed in response to an immediate operational need. This allows for maintaining momentum and capitalizing on the tactical situation at hand.
