EMU
Electronic Message Units

An Electronic Message Unit, or EMU, is a small – generally portable – electronic device, used for creating, sending and receiving text-based messages, often used in combination with a (military) radio set. In many cases, an EMU is protected by some level of encryption, which can be based on a public or a proprietary algorithm. An EMU is also known as a Digital Message Device (DMD).
