Which communication method is preferred during silent operations?

During silent operations, using hand signals and gestures is preferred because these methods allow for effective communication without making noise that could compromise the mission's stealth. The primary goal of silent operations is to maintain a low profile and minimize sound, which makes loud verbal commands and radio transmissions unsuitable options, as they can attract unwanted attention.

Hand signals and gestures can convey complex messages quickly and discreetly, enabling team members to coordinate movements and actions while remaining silent. This non-verbal form of communication is crucial during scenarios where maintaining silence is vital for the safety and success of the operation. Written orders, while clear and understandable, are not practical in dynamic environments where immediate communication is required. Thus, hand signals and gestures align perfectly with the requirements of silent operations.
