In the air raid, whether it is a Grenade or this kind of shell, its main attack capability is to attack the fragments emitted by the shell after explosion, thus causing harm to human body.

However, when people lie down, they will avoid the probability that shell fragments will hit the human body, so lying down is the most effective way to avoid injury in most cases. This method can not only avoid the attack of shells, but also may cause more damage.

The correct lying posture should be that the arms and knees support the ground, the whole trunk is far away from the ground, and the hands protect the head.

Lie down with your back to the explosion center. When lying down, your hands, pillow, chest and abdomen should be suspended (to avoid damage caused by shock wave spreading along the ground), and your mouth should be slightly opened (to make the pressure in the ear canal consistent with the outside world and avoid eardrum damage).

Choose open terrain when lying flat, and try to avoid secondary injuries caused by power system, flammable materials and tall buildings. Only in this way can it really be possible to avoid the attack of artillery shells. ?

Because when the shell hits the ground, it will produce a huge shock wave, which will spread around with the ground as the medium. If the whole trunk of the human body is prone on the ground, it is likely to be attacked by shock waves, which is likely to shatter various organs of the human body.

So it is very important to lie down on the battlefield to avoid enemy shells.
