What are the three portions of the CFF Warno?

The three portions of the CFF (Call for Fire) Warno (Warning Order) are essential for effectively conveying critical information about a fire support mission. The correct choice identifies "Type of mission," "the size of the element to FFE (Fire For Effect)," and "the method of target location."

This grouping is pivotal because it allows the fire support team to understand what kind of mission is being executed, which directly influences the planning and execution of fire support operations. Knowing the size of the unit that will be engaged by fire helps in determining the appropriate amount and type of fire support needed. Additionally, understanding the method of target location ensures that the fire support team can accurately adjust and direct fire to the intended target, enhancing coordination between ground forces and artillery or air support.

Other options do not align as accurately with the CFF Warno's requirements, leading to potential gaps in communication and operational effectiveness. For example, while options might mention aspects like enemy location or supporting fire methods, they do not fully encapsulate the necessary focus areas of the CFF Warno as specified in established military doctrine. Thus, the correct answer highlights the most critical components that enable precision in fire support missions.
