A Howitzer is a long ranged weapon between an artillery gun and a mortar

A howitzer (/ˈhaʊ.ɪtsər/) is a long ranged weapon, falling between a cannon (also known as artillery gun in the US), which fires shells at flat trajectories, and a mortar, which fires at high angles of ascent and descent. Howitzers, like other artillery equipment, are usually organized in a group called a battery. Howitzers, together with long-barreled guns, mortars, and rocket artillery, are the four basic types of modern artillery. See also: Infantry support gun A self-propelled howitzer is mounted on a tracked or wheeled motor vehicle. In many cases, it is protected by some sort of armor so that it superficially resembles a tank. This armor is designed primarily to protect the crew from shrapnel and small arms fire, not anti-armor weapons. A pack howitzer is a relatively light howitzer that is designed to be easily broken down into several pieces, each of which is small enough to be carried by mule or pack-horse. A mountain howitzer is a relatively light howitzer designed for use in mountainous terrain. Most, but not all, mountain howitzers are also pack howitzers. A siege howitzer is a howitzer that is designed to be fired from a mounting on a fixed platform of some sort. A field howitzer is a howitzer that is mobile enough to accompany a field army on campaign. It is invariably provided with a wheeled carriage of some sort. In the early 20th century, the introduction of howitzers that were significantly larger than the heavy siege howitzers of the day made necessary the creation of a fourth category, that of "super-heavy siege howitzers". Weapons of this category include the famous Big Bertha of the German Army and the 15-inch (381 mm) howitzer of the British Royal Marine Artillery. These large howitzers were transported mechanically rather than by teams of horses. They were transported as several loads and had to be assembled at their firing position.[23] These field howitzers introduced at the end of the 19th century could fire shells with high trajectories giving a steep angle of descent and, as a result, could strike targets that were protected by intervening obstacles. They could also fire shells that were about twice as large as shells fired by guns of the same size. Thus, while a 75 mm field gun that weighed one ton or so was limited to shells that weigh around 8kg, a 105 mm howitzer of the same weight could fire 15kg shells. This is a matter of fundamental mechanics affecting the stability and hence the weight of the carriage. Guns – higher velocity and longer range, single charge propellant, maximum elevation generally less than 35 degrees. Howitzers – lower velocity and shorter range, multi-charge propellant, maximum elevation typically more than 45 degrees. The onset of trench warfare after the first few months of the First World War greatly increased the demand for howitzers that gave a steep angle of descent, which were better suited than guns to the task of striking targets in a vertical plane (such as trenches), with large amounts of explosive and considerably less barrel wear. The German army was well equipped with howitzers, having far more at the beginning of the war than France.[25] Many howitzers introduced in the course of World War I had longer barrels than pre-war howitzers. The standard German light field howitzer at the start of the war (the 10.5 cm leichte Feldhaubitze 98/09) had a barrel that was 16 calibers long, but the light field howitzer adopted by the German Army in 1916 (105 mm leichte Feldhaubitze 16) had a barrel that was 22 calibers long. At the same time, new models of field gun introduced during that conflict, such as the 77 mm field gun adopted by the German Army in 1916 (7,7 cm Feldkanone 16) were often provided with carriages that allowed firing at comparatively high angles, and adjustable propellant cartridges.[26] --- During World War II, the military doctrine of Soviet deep battle called for extensive use of heavy artillery to hold the formal line of front. Soviet doctrine was remarkably different from the German doctrine of Blitzkrieg and called for a far more extensive use of artillery. As a result, howitzers saw most of the action on the Eastern front. Most of the howitzers produced by the USSR at the time were not self-propelled. Notable examples of Soviet howitzers include the M-10, M-30 and D-1. Since World War II, most of the artillery pieces adopted by armies for attacking targets on land have combined the traditional characteristics of guns and howitzers—high muzzle velocity, long barrels, long range, multiple charges and maximum elevation angles greater than 45 degrees. The term "gun-howitzer" is sometimes used for these (e.g., in Russia); many nations use "howitzer", while the UK (and most members of The Commonwealth of Nations) calls them "guns", for example Gun, 105 mm, Field, L118.
