AT present, AT4-CS is the most advanced representative of individual recoilless weapon, although it is an individual rocket tube, the motion stage of rocket projectile in the rocket tube is completely the same as that of recoilless gun, therefore, AT4-Cs can be regarded as a complex of recoilless gun and individual rocket tube, although AT4-CS is advanced to ordinary recoilless gun, its most prominent advantage lies in adding mass balance body salt water as post-spray material, realizing the limited space emission of recoilless gun, but it still has three obvious disadvantages:

1. when the shell is ignited and started, the positioning bakelite clapboard in front of the spray hole must be punctured, and the clapboard is fixed with the launching tube, so that obvious recoil is generated at the moment of starting, and the injury is caused to users;

2. although AT4-CS is equipped with balanced body saline, the saline only plays a role in balancing the quality of the projectile, and does not completely seal the propellant gas, and AT most, the propellant burns in a semi-closed state, so that the energy utilization rate of the propellant is still low, and a high initial speed is difficult to obtain.

3. The AT4-CS single-shot shell can not easily shoot, because the shell and the barrel are matched to form a complete launching system, and the bore bears the maximum bore pressure generated by gunpowder gas during launching, therefore, the single-shot shell can not be launched under the condition of no barrel, and the target can not be roughly aimed to easily shoot, therefore, the high-speed unshelled recoil-free shell gun shell which can be launched in a limited space is provided.
