Body armor, which is used for protecting the injury of warheads or shrapnel to human bodies, is equivalent to ancient armor and is indispensable military equipment. Most body armor is made of multiple layers of aramid or polyethylene PE, which is lightweight to wear, but it is difficult to protect against rifles and higher level threats due to material and technical limitations, and even if many layers of ballistic fibers are stacked enough not to be punctured by a rifle bullet, part of the impact is absorbed by the human body due to the concave deformation of the cloth, which causes secondary damage to the human body, and at this time, a ballistic insert plate is needed.

The bulletproof flashboard has two types, namely a front board and a side board, the front board can protect the front chest and the back of a human body, and the side board provides protection for the side face of the human body.
