The 15 cm schwere Feldhaubitze 18 or sFH 18, nicknamed Immergrün ("Evergreen"), was the basic German division-level heavy howitzer of 149mm during the Second World War, serving alongside the smaller but more numerous 10.5 cm leFH 18. Its mobility and firing range and the effectiveness of its 44 kilogram shell made it the most important weapon of all German infantry divisions. A total of 6,756 examples were produced.

The 10.5 cm leFH 18 is a German light howitzer used in World War II and the standard artillery piece of the Wehrmacht, adopted for service in 1935 and used by all divisions and artillery battalions. From 1935 to the end of the war, 11,848 were produced, along with 10,265 of the leFH 18/40 variant.
