Gun carriage
A gun carriage is a frame and mount that supports the gun barrel of an artillery piece, allowing it to be manoeuvred and fired.
==Early guns==
The earliest guns were laid directly onto the ground, with earth being piled up under the muzzle end of the barrel to increase the elevation. As the size of guns increased, they began to be attached to heavy wooden frames or beds that were held down by stakes. These began to be replaced by wheeled carriages in the early 16th century.〔Manucy, Albert C (1949), (''Artillery Through the Ages: A Short Illustrated History of Cannon'' ), National Park Service, Washington DC (pp. 3-5)〕
