From the velocity guns are classified for high speed and low speed.  Bullet velocity weapons less than 100 ft / sec is low or the velocity handguns and some rifles. Damage was less destructive weapons, than high speed. Low speed can also be lethal depending on which body parts are affected.

Injury due to a high-speed weapons are additional hydrostatic pressure. These factors will increase the damage.
The factors that affect network :

Bullet size.

1. Damage bullets, bullet tip of the flat caused heavy damage, the object in its path.
2. Coating bullets, expand and add a bullet surface.
3. Rounds of bullets that make the damage more extensive.
4. Deviation bullets, vertical and horizontal vibration of the axis will lead to greater damage.

Inflicted wounds consists of 3 parts :

1. Injury in
2. Wound out, not all wounds in a wound out, rare multiple exit wounds caused by shrapnel or broken bones, cuts out is generally not large and uneven surfaces.
3. Injuries, low-speed bullet with tissue damage in its path, high-speed bullet with tissue damage in its path and causes kinetic energy to the surrounding tissue.

Damage that occurs in accordance with the network density.
hard tissue such as bone, muscle, liver would be damaged more heavily on the appeal with less dense tissue such as lung. To keep in mind that after a bullet penetrated the body is not always a straight groove.
Patients with a bullet through the head, thoracic and abdomen should be immediately taken to the nearest higher service. Someone who was shot by wearing protective must consider the possibility of bruising the heart and other organs.

Bullet wound is determined by the kinetic energy that is affected by :

1. Type misiu
2. Cartridge Size
3. Barriers
4. Target distance

Kinetic energy and scattering rate according to distance, at a distance of half the speed of 40 yards from the initial velocity.
