Because the air-explosion flash detonation bomb is at a fixed-point air explosion at a distance of 5m from the ground, that is, at a height of 3.3m from the top of the personnel target (calculated according to the target height of 1.7m), it has a greater deterrent effect, and the flash detonation bomb has a greater deterrent effect on people. Eyes and ears have a more obvious impact effect, and the effect is greatly enhanced compared with ground detonation.

(2) Effectively prevent excessive damage at the center of explosion and return throw after the opponent picks up the bomb. Since the air-explosion flash detonation bomb is air-exploded at a fixed point at a height of 5m from the ground, the kinetic energy of the projectile fragments and the explosion shock wave are rapidly attenuated, which can effectively prevent fatal or permanent damage to the target. Throw it back after the bomb.

In summary, the 38mm air-explosion flash detonation bomb based on the principle of laser proximity detection involved in the utility model can overcome the shortcomings of traditional flash detonation bombs, improve the performance of non-lethal ammunition, and provide powerful support for armed police forces to carry out tasks.
