What is a tactical plan for using the weapons of a unit so that their fire will be coordinated?

The fire plan is a critical component in military operations that involves the detailed coordination of a unit's weapon systems to ensure effective and efficient engagement of targets. This plan allows for precise timing, targeting, and application of firepower, ensuring all the unit's artillery, mortars, and supporting weapon systems work in unison.

By establishing a comprehensive fire plan, commanders can lay out specific fire missions, prioritize targets, and determine the necessary support needed for various operations. This effectively integrates the day's tactical goals with the available firepower, enhancing the overall effectiveness of the unit in battle.

Other options, such as the scheme of maneuver or annexes, serve different specific purposes. For instance, the scheme of maneuver focuses on the movement and positioning of forces within the operational area, while annexes provide additional detailed instructions for planning and execution but do not solely encompass the coordinated use of weapons in fire support. The offensive plan pertains more broadly to strategies for attack operations, which can include but is not limited to fire support considerations.
