Soldier

A soldier is a person who is a member of an army. A soldier can be a conscripted or volunteer enlisted person, a non-commissioned officer, a warrant officer, or an officer. The word soldier derives from the Middle English word soudeour, from Old French soudeer or soudeour, meaning mercenary, from soudee, meaning shilling's worth or wage, from sou or soud, shilling. The word is also related to the Medieval Latin soldarius, meaning soldier (literally, "one having pay"). These words ultimately derive from the Late Latin word solidus, referring to an Ancient Roman coin used in the Byzantine Empire. In most armies, the word "soldier" has a general meaning that refers to all members of any army, distinct from more specialized military occupations that require different areas of knowledge and skill sets. "Soldiers" may be referred to by titles, names, nicknames, or acronyms that reflect an individual's military occupation specialty arm, service, or branch of military employment, their type of unit, or operational employment or technical use such as: trooper, tanker (a member of tank crew), commando, dragoon, infantryman, guardsman, artilleryman, paratrooper, grenadier, ranger, sniper, engineer, sapper, craftsman, signaller, medic, rifleman, or gunner, among other terms. Some of these designations or their etymological origins have existed in the English language for centuries, while others are relatively recent, reflecting changes in technology, increased division of labor, or other factors. In the United States Army, a soldier's military job is designated as a Military Occupational Specialty (MOS), which includes a very wide array of MOS Branches and sub-specialties. One example of a nickname for a soldier in a specific occupation is the term "red caps" to refer to military policemen personnel in the British Army because of the colour of their headgear. Infantry are sometimes called "grunts" in the United States Army (as the well as in the U.S. Marine Corps) or "squaddies" (in the British Army). U.S.
