What elements are required inside the CFFZ symbol?

The CFFZ symbol, which stands for Close Fire Support Zone, is essential for coordinating fire support in military operations. The elements required inside the CFFZ symbol include the identification of the unit involved, the Date-Time Group (DTG) of the start of the operation, and the DTG of the end of the operation.

Having the unit specified allows for clear identification of which forces are involved in the close fire support operations, ensuring that the correct troops receive and coordinate the necessary fire support. The inclusion of both the start and end DTGs is critical for establishing a timeline for the operation, which helps in coordinating efforts and avoiding friendly fire incidents. This information also aids in planning and deconflicting actions during the specified timeframe.

In contrast, the other answer choices do not encompass all the necessary components essential for a CFFZ. While they may contain some relevant elements, they do not focus specifically on the timing and unit identification that are paramount for effective close fire support coordination.
