Which situation justifies calling for FFE during the use of successive bracketing?

Calling for Fire for Effect (FFE) during the use of successive bracketing is justified when you have successfully narrowed down your target's location through the bracketing process. The bracketing process involves firing rounds that progressively narrow the area where the target is believed to be located until an accurate impact point is determined.

When you split the 100-meter bracket, it indicates that you have established a significant range boundary around your target and are closer to identifying the exact target location. At this point, if you observe impacts on or near the target after splitting the 100-meter bracket, it implies that you have enough information to confidently engage with a full fire mission (FFE). This means that you have conducted sufficient adjustments and are now ready to deliver fire in a concentrated manner.

In contrast, splitting the smaller brackets, such as the 50-meter or 38-meter brackets, does not typically justify immediate FFE since they represent narrower areas that may not yet provide a clear indication of where the target is within that area. A registration point also does not directly lead to FFE; it merely serves as an accurate point of reference for future fire missions. Thus, utilizing the information gained from splitting the larger bracketing range at 100 meters indicates readiness
