Which of the following is NOT a type of fire support coordination measure?

The identification of Air Support Coordination Measure (ASCM) as not being a type of fire support coordination measure is based on the definitions and classifications within fire support terminology. The other options—Fire Support Coordination Line (FSCL), No Fire Area (NFA), and Safety Zone (SZ)—are all recognized types of fire support coordination measures used to prevent friendly fire and to facilitate the safe and effective use of fire support assets in a combat environment.

The FSCL is a critical line that delineates where fire support operations can occur and helps command and control efforts as it informs ground and air forces about where they can use fire support without restrictions. The NFA is established to protect certain areas from any fire support, ensuring the safety of particular assets or forces. The Safety Zone provides a buffer area where friendly forces can operate without the risk of being engaged by fire support.

In contrast, the term ASCM does not have the same established recognition or definition as a fire support coordination measure. Instead, it relates more to broader air operations and coordination but is not specified in the same way as the measures designed specifically for managing fires on the battlefield. This distinction clarifies why ASCM is correctly identified as not fitting into the category of fire support coordination measures compared to
