Gate guardian

A gate guardian or gate guard is a withdrawn piece of equipment, often an aircraft, armoured vehicle, artillery piece, or locomotive, mounted on a plinth and used as a static display near to and forming a symbolic display of "guarding" the main entrance to a site, especially a military base.^[1][2] Commonly, gate guardians outside airbases are decommissioned examples of aircraft that were once based there, or still are.^{[citation needed]}
