The Skoda 150 mm Model 1918 was a heavy mountain howitzer, manufactured by Skoda Works. The design was begun during World War I, but the first prototype was completed as the war ended. After 1938, the Wehrmacht designated the few built as 15 cm GebH 18(t), although it's uncertain if they were actually used. The gun could be transported on six carts; each cart pulled by at least two horses or mules. The barrel assembly required three towing animals.
