7.5-cm leichte Infantriegeschütz 181,
7.5-cm leIG 181
During World War I Germany learned that infantry battalions should have artillery support.1 In 1927 Rheinmetall-Börsig developed a design for the 7.5 cm leIG 18.1,2 It was in service by 1932.1
Design
The first models had wooden spoked wheels but this gave way to solid metal with rubber tires to be towed by motorized vehicles.1,2
A lever moved the entire barrel up and exposed the loading chamber.1
Usage
The 7.5-cm leIG 18 became the standard artillery weapon in the support companies of the infantry regiments.2
