The armament of the SdKfz 138/1 was a 150mm (15 cm) sIG 33 main gun and an MG 34 for defense of the crew. Some of the draw backs for the main gun included the fact that an ammunition carrier had to take most of the 150mm shells and in order to fire in a new direction, the entire vehicle had to turn in the intended direction. The only variant of the Grille was the Ausf. M.
Grille Ausf. MEdit
The SdKfz 138/1 Ausf. M was the only variant of the Grille and it was based on the Panzer 38(t) Ausf. M. As such the engine was placed in the middle of the vehicle and the gun mount was moved to the rear of the hull. Although these are the only major differences as the Ausf. M had the same gun, engine, and suspension as the Ausf. H.
The SdKfz 138/1 Ausf. H began production in Febuary of 1943 and the SdKfz 138/1 Ausf. M began production in April 1943. The models were mainly produced by BMM and in total, about 490-500 Grilles were produced. They were used by panzer divisions in the Soviet Union along with units in Poland and France. They were used up to 1945 and they also served in Tunisia where they fought enemy artillery and tanks.
