What gesture indicates a cease fire to the unit?

The gesture of raising the hand to the forehead and swinging the arm up and down effectively communicates a cease fire to the unit due to its visibility and simplicity. This motion stands out, especially in high-stress environments where clear and unmistakable signals are critical. By elevating the hand to the forehead, it captures attention, and the swinging motion creates a distinct and rhythmic signal that can be easily recognized from a distance, ensuring all members of the team understand the command without confusion.

In contrast, simply pointing at each Marine lacks the broad visibility needed in chaotic situations, making it less effective. Clapping hands three times might not be as immediately recognizable as a tactical gesture for cease fire and could be misinterpreted based on the context. Holding a weapon at shoulder level while looking around does not convey a clear message of cease fire; instead, it might imply readiness or uncertainty. Thus, the first option combines clarity and action, making it the most effective choice for indicating a cease fire.
