What is the maximum allowable headwind for firing smoke grenades?

The correct answer indicates that a headwind of up to 12 miles per hour is permissible for the safe deployment of smoke grenades. This maximum limit is established to ensure that the smoke produced by the grenades disperses effectively in the intended direction and remains within a controlled area. A stronger headwind can lead to unpredictable smoke drift, which poses safety risks to personnel and may affect the intended use of the smoke for concealment or signaling purposes.

In this context, it is critical for Range Safety Officers to understand the impact of wind conditions on operational effectiveness and safety. Operating within established limits helps mitigate potential hazards associated with visibility and unintended exposure to smoke.
