During World War I Germany learned that infantry battalions should have artillery support. In 1927 Rheinmetall-Börsig developed a design for the 7.5 cm leIG 18. It was in service by 1932.
The first models had wooden spoked wheels but this gave way to solid metal with rubber tires to be towed by motorized vehicles.
A lever moved the entire barrel up and exposed the loading chamber.
The 7.5-cm leIG 18 became the standard artillery weapon in the support companies of the infantry regiments.
This was the light mountain infantry version. It was developed in 1935. It could be broken down into 10 packs for mules or light vehicles. The trailing legs became tubular steel and the shield was optional.
This was to be used by the Fallschirmjäger (parachute troops). It could be broken down into four loads and put into special containers for parachute dropping. Only six were built as by that time the recoilless guns were being used.
