A good set of body armor can mean the difference between life and death.
Body armor isn’t just for the military and police in tactical situations. Bullet resistant vests are for anyone who puts themselves in the way of danger. If you might catch a bullet, it’s best to catch it with a nice thick piece of Kevlar.
There are many types, weights, and styles of body armor on the market today. Remember: The best body armor is the body armor you are wearing.
The History of Kevlar
This NIJ Standard establishes minimum performance requirements and test methods for the ballistic resistance of personal body armor designed to protect the torso against gunfire. The standard is limited to ballistic resistance only and does not address resistance from knives or other sharply pointed objects. It reviews NIJ body armor classifications, details requirements (i.e., acceptance criteria, workmanship, armor backing material, and so forth), and discusses test methods (i.e., velocity measurement equipment, wet conditioning, test preparation, and so forth). This standard serves as a general revision to NIJ Standard 0101.03 from April 1987.
This standard, the first of its kind in the United States, specifies the minimum requirements for body armor designed to protect the torso against slash and stab threats. This NIJ Standard describes the test methodology used for the assessment and focuses primarily on knives that are readily available from sports equipment retailers - ones of high quality that feature very sharp machine-ground cutting edges and fine points. Lower quality, prison-made knives, ice picks, and shivs are not addressed in this report. The threats treated in this standard are from hand-delivered impacts from instruments whose points or tips lie near the centerline of the clenched fist holding the weapon.
This user guide is your information tool. It lists the many benefits of wearing body armor, along with the few limitations of which you should be aware. It provides detailed safety information and lists specific instructions on the care and maintenance of body armor that will extend its effective usefulness.
This NIJ Guide responds to questions about the selection and use of body armor for law enforcement and corrections. It includes information from the latest NIJ standard on ballistic resistance of body armor (0101.04), as well as information on NIJ’s new standard on stab resistance of body armor (0115.00). The guide provides information to help determine what level of protection is consistent with the threats to which individual officers are exposed. It describes the various body armor styles available, along with the proper care of body armor in service. The NIJ standards are discussed in detail, as well as the use of the standards in body armor procurement.
NIJ and its National Law Enforcement and Corrections Technology Center (NLECTC) administer a voluntary compliance testing program to assess whether models of ballistic- and stab- resistant body armor comply with NIJ Standards. The NIJ Standards identify minimum performance criteria critical to protecting officers from various threats.

Lightweight body armor or bullet proof vests have been widely available for use by law enforcement personnel for more than 20 years. Humans throughout recorded history have used various types of materials as body armor to protect themselves from injury in combat and other dangerous situations. At first, protective clothing and shields were made from animal skins. As civilizations became more advanced, wooden shields and then metal shields came into use. Eventually, metal was also used as body armor, what we now refer to as the suit of armor associated with the knights of the Middle Ages. However, with the advent of firearms (c.1500), most of the traditional body armor were no longer effective. In fact, the only real protection available against firearms were man-made barriers, such as stone or masonry walls, or natural barriers, such as rocks, trees, and ditches.
When a handgun bullet strikes body armor, it is caught in a “web” of very strong fibers. These fibers absorb and disperse the impact energy that is transmitted to the vest from the bullet, causing the bullet to deform or “mushroom.” Additional energy is absorbed by each successive layer of material in the vest, until such time as the bullet has been stopped.
In this edition of HowStuffWorks, we’ll look at soft body armor and other modern body armor technologies to see how they can stop bullets. We’ll also find out about the range of body armor options available and see how the government tests and rates body armor.

Body armor FAQ from JustNet
Every year, about 60 sworn police officers are shot to death in the line of duty. At the same time, about 20 are saved by wearing body armor. Had all the officers shot in recent years been wearing body armor when shot, another 15 per year would likely have been saved from fatal gunshot wounds, roughly doubling the present number saved, and more than 15 others would likely have been saved from death by other causes.

Simula announced that it has received a U.S. patent for its latest body armor design. The unique design enables fabrication of the industry’s lightest-weight body armor, protecting the wearer against handgun threats.
Frangible bullets, which are composites of hybrid materials either pressed together at high pressure or glued together with adhesives, are primarily used in training exercises to reduce lead hazards on firing ranges. Frangible bullets are designed to break up into smaller pieces upon contact with harder objects or surfaces. These small fragments quickly lose energy and significantly reduce the possibility of injury from ricochet, making them ideal for use in training exercises.
National Institute of Standards; Electronics and Electrical Engineering Laboratory; Office of Law Enforcement Standards: Weapons and Protective Systems: This project area provides ongoing technical support and research for the National Institute of Justice (NIJ) standard for ballistic-resistant body armor (bullet-resistant vests), which OLES first developed for NIJ in 1972. The body armor program is part of NIJ’s successful Law Enforcement and Corrections Standards and Testing Program, through which companies may have their products voluntarily certified as compliant with the standard. Ballistic-resistant body armor has been credited with saving more than 2500 lives, and the program’s evaluations of new materials and ballistic threats and its revisions of the standard help ensure the continued effectiveness of this technology. This project area also develops and supports other equipment performance standards vital to the safety of law enforcement and corrections personnel, including stab-resistant body armor; ballistic helmets; riot helmets and face shields; bomb suits; metallic handcuffs; and firearms.

Prevention is the best medicine. But if prevention fails then protection is the next line of defense. Body armor is the last line of defense a soldier has on the battlefield. Technology is making it better.
