A gun carriage is a frame or a mount that supports the gun barrel of an artillery piece, allowing it to be maneuvered and fired. These platforms often had wheels so that the artillery pieces could be moved more easily. Gun carriages are also used on ships to facilitate the movement and aiming of large cannons and Guns. These are also used in the funeral procession of any higher authority of any state and country.
The Mortier de 280 TR Modèle 1914 Schneider was a French siege howitzer manufactured by the Schneider et Cie company, used during World War I. The howitzer had its origins from a Russian Army policy to upgrade its artillery park after the poor showing of Russian artillery in the 1904-5 Russo-Japanese war. In 1909 an agreement was signed between Schneider and the Russian armaments manufacturer Putilov to jointly develop and produce a number of artillery types. One of these types was a 279.4 mm (11-inch) siege howitzer with a range of 6,000 m (20,000 ft) to replace very old Russian guns of similar calibre. Schneider delivered the first prototype of the siege howitzer to the Russians in 1912 for extensive testing. Although the Russians found the gun was unable to penetrate the heaviest reinforced concrete fortifications its general performance was judged satisfactory which led to an order for 16 howitzers to be delivered in 1915. The French Army expressed interest in the Schneider howitzer as a possible replacement for the Mortier de 370 Mle 1885 De Bange. After some dithering by French authorities 18 howitzers were ordered in 1913. Delivery of the howitzers to Russia and France was delayed by the general mobilisation of 1914 which disrupted industrial production. During the war 126 howitzers were delivered to the French Army and 26 to Russia as the 280 mm Schneider Mortar Model 1914/15 before the 1917 revolutions. In addition another 25 barrels were installed post-WW1 on the Saint-Chamond heavy self-propelled gun chassis as the Mortier 280 mm TR de Schneider sur affût-chenilles St Chamond.
