Objective To provide the ideas and methods of optimizing and improving the packaging specification for military auxiliary oil. Methods The characteristics of packaging specification of U.S. military auxiliary oil from POL products guide for ground vehicle and equipment materiel systems were analyzed using statistical analysis. Results U.S. military packaging specification for the auxiliary showed three features, diversification, standardization and serialization, among which serialization was very obvious, and the distribution characteristics of the serial specification were related to the use of military auxiliary oil and the rules of equipment oil usage. Conclusion It has proved that the packaging specification of military auxiliary for ground equipments should be based on standardization and serialization. The series of packaging specification should be based on the laws of military auxiliary oil usage. The serialization of packaging specification would be helpful for the acceleration of logistical informationization.
