Field gun
Today there is no longer a use for the field gun. The role for small and highly mobile artillery has been taken over by the mortar which can be carried by a soldier. These have replaced almost every artillery piece smaller than 105 mm. Gun-howitzers fill the middle ground, mostly the 155 mm NATO or 152 mm former USSR models. The need for a long-range weapon is filled by rocket artillery, or aircraft. Modern gun-artillery such as the L118 105mm light gun is used to provide fire support for infantry and armour at ranges where mortars are impractical. Soldier carried mortars lack the range or hitting power of gun-artillery. In between is the rifled towed mortar. This weapon (usually in 120mm calibre) is light enough to be towed by a Land Rover, has a range of over 6,000m and fires a bomb with the power of an artillery shell.
