Which form of communication is used in military signalling?

Military signaling often utilizes a variety of communication methods, including visual signals (such as flags, lights, or smoke), sound signals (such as whistles or horns), and electronic communications (like radiOS and secure messaging systems). These methods are designed for clarity and efficiency, enabling units to convey commands and information rapidly over distances. Additionally, coded signals, such as Morse Code or specific tactical signals, are frequently employed to ensure secure and unambiguous communication.
