The Infanteriegeschütz 18 or IG 18 was an infantry gun that was used by Germany during World War II.


The IG 18 was a simple artillery piece, using a box trail type mount. The weapon itself could fire a 75 mm shell weighing in at 5.9 kilograms at a maximum distance of some 3,400 meters.[1] Designed to be able to be carried around by horses or small motor vehicles, the IG 18 itself weighed around 400 kilograms while its overall length was 2.5 meters.

The gun fired each round with a muzzle velocity of 223 meters per second and could elevate from -10˚ to +35˚. The gun could also traverse a total of 12˚ in either direction. In practice, the gun was effective in combat, serving throughout the war with German forces.


The first variant of the IG 18 series was the Ie.GebIG 18 mountain gun conversion which was capable of being broken down into six key components for easier travel in mountain passes.[2] Also developed but only produced in a limited production run was the IG 18F airborne gun which was similar to the Ie.GebIG 18 in that it could easily be transported. However, the IG 18F differed in that it had no gun shield and had far smaller road wheels.


The Infanteriegeschütz 18 was first developed in 1927 by Rheinmetall. Production of the new weapon subsequently began in 1932 with the Wehrmacht accepting it later that year. Quickly becoming one of the standard artillery pieces of the Wehrmacht, the IG 18 saw service on all fronts that the Heer and Waffen-SS took part in. The gun's ability to provide quick and effective indirect fire would prove invaluable in many combat situations with which the German troops would encounter. In total, some 12,000 of all different types of IG 18 infantry guns were produced during the weapon's production run.
