The two German infantry guns - the 15cm and the 7,5cm were used in much the same way as mortars would later be. Their design was based on WWI experience with mortars - "Minenewerfer" - and the two guns were called Minenwerfer early on in their development.

They differed from howitzers by having a very high elevation, about 75 degrees. I dont know what the shortest range was, but it cannot have been much. The smallest charge gave the 7,5cm a max. range of 800 meters and fired the round at a whooping 92 m/s. Max. range with the largest charge firing HE at 210 m/s was 3375 meters.

The 15cm gun reached 1475 meters max. with the smallest charge and 4700 meters with the largest.
