Which element can be changed during Changes to CFF?

• A. Target location
• B. # of rounds
• C. Time of flight
• D. Target #

Answer: (B)

The key idea is that a Change to Call for Fire is used to adjust the same fire mission without rewriting the entire mission. The only thing you can change on the fly is the number of rounds to be fired. This is a simple resource adjustment that keeps the target, the method of fire, and the designated location the same.

Altering the target location, target number, or time of flight would redefine the mission details and typically requires issuing a new CFF rather than a change to it. If the observer needed to shift the target or modify the fuse or range, they would initiate a new fire mission or perform a proper adjustment. So, the element that can be changed during Changes to CFF is the number of rounds.
