In order to solve the problems in the process of oil packaging replenishment and the development of equipment, the oil supply is highly efficient, accurate and convenient, and the research on modular oil equipment is carried out. Combined with military application practice, use modulus theory and modular design ideas, design the oil drum packaging series and proposing new ideas for tactical oil replenishment. The results show that the method can solve the current shortage of tactical oil support equipment, and open up the last 1 km of oil supply in non-cluster combat conditions to enhance the self-protection capability of combat equipment.
