Signal Corps

The Signal Corps is a military branch, usually subordinate to a country's army. Many countries have a Signal Corps, whose main function is usually communication (in modern times, usually radio or telephone communication on the battlefield). The word corps is used in the British sense (meaning a branch of military service, such as Corps of Engineers), rather than the American sense (meaning an organizational unit below army and above division). Subordinate units include signal regiments, battalions, etc.

• The U.S. Army Signal Corps was founded in 1860 by Major Albert J. Myer.
• The Royal Corps of Signals was founded in the United Kingdom (under the name Telegraph Battalion Royal Engineers ) in 1884.
