The nickname of missiles and free rockets is listed in place of the missile diameter.
Type indicates the basic role of the weapon, or basic weapon type.
ICBM, IRBM, and other strategic systems are not included. The wide range of mortars available precludes a full listing here. However, some of the most representative or common ones are listed here. Many other models are local copies of those listed, or are based on their designs. Mortars are largely limited by the ammunition available, not the system.
