Because there are some problems that exist in the current teaching of ammunition courses, such as theoretical explanation cannot be carried out and the practical operation is not safe, and com-bining the advantages of virtual classrooms. Therefore, in order to improve the teaching quality of ammunition courses, the concept about ammunition virtual classrooms is put forward. The ammunition virtual classroom will be divided into multiple areas, including virtual teaching area, virtual ammunition storage area, virtual operation practice area and new ammunition area, etc. Through designing these areas, students will be able to independently master the learning progress, participate in interaction actively, and improve the learning effect in ammunition courses. The introduction of virtual classrooms will open a new direction for the teaching of ammunition courses.
