摘要： An improved mortar training ammunition device is characterized by a propulsion module which can be altered for short range and full range operation. The module includes a stabilizer tube containing spaced groups of openings which are selectively opened or closed by rings mounted on the tube. Propelling charges are mounted on the rings. By selecting simulated or active propelling charges and the condition of the openings, the device can be used for garrison or field training.
