Artillery

Historically, artillery (from French artillerie) refers to any engine used for the discharge of projectiles during the war. The term also describes ground-based troops, who primarily manned such weapons. The word is derived from the Old French verb attilier, meaning "to equip". This term includes coastal artillery which traditionally defended coastal areas against seaborne attack and controlled the passage of ships using their ability to deny access through the threat of coastal fire. It also includes land-based field artillery. With the advent of powered flight at the start of the 20th century, artillery also included ground-based anti-aircraft batteries.
