SD:LG 40

 is a German Support unit.

Overview
A recoilless gun developed by Krupp, Leichtgeschutz 40 competed with Rheinmetall's LG 42. Both weapons were introduced to provide paratrooper and mountain units with an effective artillery support weapon, inspired by the success of Rheinmetall's 7,5 cm LG 40 during Operation Mercury (the invasion of Crete) in 1941.

In the proper organization of the Fallschirmjäger Battalion there is Infantry Gun Platoon of two 7.5 cm Infantry Guns in the Heavy Company.
