True / False: A quick smoke mission requires the observer to send length, maneuver target line, wind direction, and duration in the call for fire.

A quick smoke mission is indeed initiated with specific information to ensure effective deployment and coverage of the smoke. When calling for a quick smoke mission, the observer needs to provide essential details that include the length for the shape and coverage area of the smoke, the maneuver target line to indicate the direction of the smoke, the wind direction to understand how the smoke will be affected by environmental conditions, and the duration to specify how long the smoke is needed to mask the movement or target.

Each of these elements plays a critical role in the success of a smoke mission. The length helps determine how far the smoke will disperse; the maneuver target line directs the placement of the smoke in relation to the intended area; wind direction helps predict where the smoke will drift, which is crucial for maintaining the desired concealment effect; and duration ensures that the smoke remains in place long enough to serve its purpose without being prematurely dissipated.

This accurate and concise relay of necessary information is essential for a quick response and effective execution of the mission, which is why the statement is true.
