guidance=The 7.58 cm Minenwerfer a.A. (alter Art or old model) (7.58 cm leMW) was a German
First World Warmortar. The Russo-Japanese Warof 1905had shown the value of mortars against modern fieldworks and fortifications and the Germans were in the process of fielding a whole series of mortars before the beginning of World War I. Their term for them was Minenwerfer, literally mine-thrower, and they were initially assigned to engineer units in their siege warfare role. By the Winter of 1916-17 they were transferred to the infantry where the leMW's light weight permitted them to accompany the infantry in the advance. In common with Rheinmetall's other Minenwerferdesigns the leMW was a rifled muzzle-loaderand had hydraulic cylinders on each side of the tube to absorb the recoil forces and spring recuperators to return the tube to firing position. It had a rectangular firing platform with limited traverse and elevation. Wheels could be added to ease transportation or it could be carried by at least six men. In 1916a new version, designated as the n.A. or neuer Art, was fielded that had a new circular firing platform that added a turntable which permitted a full 360 degree of traverse. It also had a longer convert|16|in|mm barrel and could be used for direct fire between 0° and 27° elevation if the new convert|90|kg|lb trail was fitted to absorb the recoil forces. In this mode it was pressed into service as an anti-tankgun.
