Flag signaling

Flag signaling is a communication method where different flags, colors, or patterns are used to convey messages, often over distances. Each flag or combination of flags has a specific meaning, much like a language. This method is commonly used by ships and military units to send instructions, warnings, or status updates without spoken words, especially when radio communication isn't possible or reliable. By raising and lowering flags in particular sequences, senders can transmit complex messages quickly and effectively, enabling coordinated actions and safety across vast areas.
