Military communications involve all aspects of communications, or conveyance of information, by armed forces. Military communications span from pre-history to the present. The earliest military communications were delivered by humans on foot. Later, communications progressed to visual and audible signals, and then advanced into the electronic age. Examples from Jane's Military Communications include text, audio, and facsimile, Tactical and ground-based communications, terrestrial microwave and tropospheric scatter, naval and satellite communications systems and equipment, surveillance and signal analysis, encryption and security and direction-finding and jamming.[1]


The first military communications involved the use of runners or the sending/receiving of simple signals (sometimes encoded to be unrecognizable). The first distinctive tactics of military communications were called signals. Modern units specializing in those tactics are usually designated as Signal Corps. The Roman system of military communication (Cursus publicus or cursus vehicularis) is an early example of this. Later, the term Signals and Signaller became a word referring to a highly-distinct military occupation dealing with general communications methods (similar to those in civil use) rather than with weapons.

Present-day military forces of an informational society conduct intense and complicated communicating activities on a daily basis, using modern high-tech telecommunications and computing methods. Only a small portion of these activities is directly related to combat actions.

Modern concepts of Network-centric warfare (NCW) rely on network-oriented methods of communications and control to make existing forces more effective.

Military Communications Equipment[edit]

Drums, horns, flags, and riders on horseback were the first methods used to send messages over distances.

Many modern pieces of military communications equipment are built to encrypt and decode transmissions and survive rough treatment in hostile climates. They use many frequencies to send signals to other radios and to satellites.

Military communications - or comms - are activities, equipment, techniques, and tactics used by the military in some of the most hostile areas of the earth, not only geographically but also in challenging environments such as battlefields, on land, underwater and in the air. Military comms include Command, Control, Communications and Intelligence and were known as the C3I model before computers were fully integrated. The U.S. Army expanded the model to C4I when it recognized the vital role played by automated computer equipment to send and receive large, bulky amounts of data.

The first military communications tool was the communication automobile designed by the Soviet Union in 1934 to send and receive signals. The signals were encoded to help prevent the enemy from intercepting and interpreting top-secret communications. The advent of distinctive signals led to the formation of the Signal Corps, a group specialized in the tactics of military communications. The Signal Corps evolved into a distinctive occupation where the signaler became a highly technical job dealing with all available communications methods including civil ones.[citation needed]

In the modern world, most nations attempt to minimize the risk of war caused by miscommunication or inadequate communication by pushing the limits of communication technology and systems. As a result, military communication is more intense, complicated, and often motivates the development of advanced technology for remote systems such as satellites and aircraft, both manned and unmanned, as well as computers. Computers and their varied applications have revolutionized military comms. Although military communication can be used to facilitate warfare, it also supports intelligence-gathering and communication between adversaries, and thus sometimes prevents war.

There are six categories of military comms: the alert measurement systems, cryptography, military radio systems, nuclear command control, the Signal Corps, and network-centric warfare.

The alert measurement systems are various state of alertness or readiness for the armed forces used around the world during a state of war, act of terrorism or a military attack against a state. They are known by different acronyms, such as DEFCON, or defense readiness condition, used by the U.S. Armed Forces.

Cryptography is the study of methods of converting messages into disguised, unreadable information, unless one knows of the methods of decryption. This military comms method ensured that the messages reached the correct hands and eyes or ears. Cryptography is also used to protect digital cash, signatures, digital rights management, intellectual property rights, and secure electronic commerce. It is also used in computing, telecommunications and infrastructure.

Military comms use many kinds of radios. A few are ACP-131, AN/ARC-164, AN/ARC-5, HWU transmitter, Hallicrafters SX-28, SCR-197, SCR-203, and SCR-270 radar.
