A self-propelled gun (SPG) is a form of self-propelled artillery, and in modern use is usually used to refer to artillery pieces such as howitzers.
Self-propelled guns are mounted on a motorised wheeled or tracked chassis (because of this they are sometimes visually similar to tanks). As such the gun can be maneuvered under its own power as opposed to a towed gun that relies upon a vehicle or other means to be moved on the battlefield. Self-propelled guns are combat support weapons; they are employed by combat support units fighting in support of, or attached to, the main combat units: infantry and armour(tanks).
