In a quick smoke mission, what critical component is NOT typically included in the observer's call for fire?

In a quick smoke mission, the observer's call for fire typically does not include the target coordinates. This is because quick smoke missions are often executed under time constraints where the primary focus is on the immediate requirements for smoke delivery rather than precise targeting. The emphasis is on the effective use of smoke to obscure visibility, create cover, or signal, which does not necessitate the same level of precision in coordinates as more conventional artillery strikes.

Other elements, such as the length of smoke, wind direction, and duration, are crucial for ensuring the smoke screen's effectiveness and proper execution. Length determines how far the smoke will extend, wind direction influences how the smoke will drift and settle on the battlefield, and duration indicates how long the smoke should persist to achieve the desired effect. In this context, the omission of specific target coordinates aligns with the operational need to deploy smoke rapidly and adaptively in response to dynamic battlefield conditions.
