FORENSICS Wound ballistics
The term ballistic trauma or gunshot wound (GSW) refers to a form of physical trauma sustained from the discharge of arms.
[1] The most common forms of ballistic trauma stem from firearms used in armed conflicts, civilian sporting, recreational pursuits and criminal activity.
[2]Ballistic trauma is sometimes fatal for the recipient, or causes long term negative consequences.
AMMUNITION A BULLET is a projectile propelled by a
firearm, sling, or air gun. Bullets do not normally contain explosives, but damage the intended target by impact and penetration. The word "bullet" is sometimes colloquially used to refer to ammunition in general, or to a cartridge, which is a combination of the bullet, case/shell, powder, and primer. This use of 'bullet' when 'cartridge' is intended, leads to confusion when the components of a cartridge are discussed or intended. See the reference section for more detail.
FIREARMS A firearm is a portable gun, being a barreled
weapon that launches one or more projectiles often defined by the action of an explosive.[1][2][3] Firearms first appeared in 13th century China when the man portable fire lance (a bamboo or metal tube that could shoot ignited gunpowder) was combined with projectiles such as scrap metal, broken porcelain, or darts/arrows.[4] The technology gradually spread through the rest of Asia and into Europe. In older firearms, the propellant was typically black powder, but modern firearms use smokeless powder or other propellants. Most modern firearms (with the notable exception of smoothbore firearms) have rifled barrels to impart spin to the projectile for improved flight stability.
FIREARMS Handgun The smallest of all firearms is
the handgun. There are three common types of handguns: single-shot pistols (more common historically), revolvers, andsemi-automatic pistols. Revolvers have a number of firing chambers or "charge holes" in a revolving cylinder; each chamber in the cylinder is loaded with a single cartridge. Semi-automatic pistols have a single fixed firing chamber machined into the rear of the barrel, and a magazine, usually removable, so they can be used to fire more than one round.
FIREARMS Shotgun A shotgun usually retains its
ancestor's smooth bore, and while originally designed to fire a packet of relatively small shot pellets, is also capable of firing larger slugs, or specialty (often "less lethal") rounds such as bean bags, tear gas or breaching rounds. Rifles have a very small impact area but a long range and high accuracy. Shotguns have a large impact area with considerably less range and accuracy. However, the larger impact area can compensate for reduced accuracy, since shot spreads during flight; consequently, in hunting, shotguns are generally used for flying game
FIREARMS Rifle An automatic rifle is a
magazine-fed firearm, wielded by a single infantryman, that is chambered for rifle cartridges and capable of automatic fire. The M1918 Browning Automatic Rifle was the first U.S. infantry weapon of this type, and was generally used for suppressive or support fire in the role now usually filled by the light machine gun.
