If a rescuer needs to communicate discreetly, what should they consider using?

Using hand signals is an effective way for a rescuer to communicate discreetly during a rescue operation. Hand signals can convey messages quickly and silently, minimizing the risk of alerting a potential threat or disturbing a victim. This method allows for clear communication between team members, especially in situations where verbal communication may not be feasible due to noise, distance, or the need to maintain stealth.

While written notes might seem like a viable option, they can be impractical in dynamic, rapidly changing situations where immediate feedback is necessary. They also risk being lost or not conveyed quickly enough. Facial gestures can be a useful form of non-verbal communication but may be less effective than hand signals, especially when visibility is limited or when team members are not in close proximity. The use of song does not align with the needs of discreet communication in a rescue scenario, as it would likely draw attention rather than maintain secrecy. Therefore, hand signals stand out as the most suitable choice for discreet communication among rescuers.
