“The 8 cm Granatwerfer 34 (8 cm GrW 34) was the standard German heavy mortar throughout World War II. It gained a reputation for extreme accuracy and rapid rate of fire, although much of the credit should go to the training of the crews.
The weapon was of conventional design and broke down into three loads (smooth bore barrel, bipod, baseplate) for transport. Attached to the bipod were a traversing handwheel, and a cross-leveling handwheel below the elevating mechanism.
A panoramic sight was mounted on the traversing mechanism yoke for fine adjustments. A line on the tube could be used for rough laying”Wiki
