What is the method used for controlling time of delivery of fire?

The method known as "At My Command" is utilized for controlling the timing of fire delivery effectively. This command gives the FIST leader precise control over when the fire is to commence. It allows for coordinated timing that is dependent on the evolving situation on the battlefield, ensuring that the fire can be synchronized with the movement of friendly forces or the timing of an assault. This option is particularly useful for ensuring that fire support can be integrated seamlessly with other operations, contributing to the overall effectiveness of the mission.

In contrast, "Fire When Ready" indicates that the units are to commence firing when they are prepared to do so, without an explicit command to begin. This method allows for flexibility but can lead to uncoordinated strikes if not managed carefully.

"Repeat" is a command typically used to instruct artillery units to replicate a previous fire mission, and it does not inherently control the timing of delivery.

"Mark" usually refers to a command to highlight a location or target, often used in conjunction with air or artillery support, but it does not pertain directly to the timing of fire delivery commands.

Understanding the distinction among these methods is crucial for effective communication and coordination within a Fire Support Team.
