The PELE is new concept multipurpose ammunition that not includes the energy material, and has a certain penetration performance and good fragmentation capability. It can be effectively against the progressively armored vehicles and semi-hard targets in modern battlefield, including armored troop carrier, command vehicle, self-propelling gun and so on, and the countries in the world are actively studying this ammunition. In this paper, its action on the future battlefield and present level of research overseas were presented, its lethal effect and the influence of body and penetrator on the damage effectiveness of the ammunition were analyzed, the damage effectiveness of different body material and wall thickness on the ammunition were calculated by simulation, the influence rule of body material and wall thickness, and penetrator material on the damage effectiveness of the ammunition was verified. The results of test were basically in accordance with that of simulation calculation.
