The main mortar for the Germans in WW2 was the 81mm Granatwerfer 34. It was a very effective and accurate weapon that could provide long range, on call fire support. It's crew could carry it in 3 pieces: base plate, tube and bipod. With enough ammunition it could maintain a rate of fire of around 15 to 20 rounds per minute out to a maximum range of 2,400 meters.
