Bulletproof clothing is the most interesting thing I have ever seen in my life. There is not really a problem of bulletproof clothing besides it is very expensive to make it. It is very expensive just because of the materials. The materials are spider-silk, vectran and Kevlar. The history of bulletproof has been worn for thousands of years. Even the medieval Europe worn body armor. By the 1500’s, they changed the development of cannons and guns. Bulletproof in the encyclopedia means the protection of bullets, knives and puncture wounds. They have made antiballistic protective clothing. The material of it is single layer or multilayer package. The bulletproof clothing basically looks like a very strong net.
Bulletproof clothing is really made up of seven layers of bullet-resistant webbing. The three types of the layers are the carrier, Kevlar and plastic film. The body armor just looks like a very strong net. Kevlar is strong, but they also make bulletproof with another material is called vectran. Vectran is 5 to 10 times stronger than steel. They have another rapidly emerging fiber its called spider silk. The resulting of spider silk is biosteel. A strand of biosteel can be up to 20 times stronger than a strand of steel. To have a hard body armor, you have to make I out of thick ceramic or metal plates. It’s extremely hard enough for it to deflect bullets or other weapons. When the bullet makes contact with the material of bulletproof. A police officer or military will wear this type of protection when it is a high risk of attack. The swat team would definitely wear this type of protection too. But when they are on an everyday mission they would mainly wear soft body armor. This would give these types of people the faith in them ...

During the years leading up to and during the American Civil War there were a number of advancements in firearms technology. This paper will focus on a few of those advancements, namely the inventions of the Minié ball, the Spencer and Henry repeating rifles, and of the Gatling gun.
Finally, the third change involves the utility uniform itself, also known as “cammies”, giving it a complete makeover. The current cammie design for all branches of the Armed Forces is over twenty years old. The textile industry has made many advances in the production of clothing providing more comfort and durability. Revolutionary advances within the clothing industry, Velcro and zippers, are being tested on the new cammie uniform.
“Bulletproof vests are modern light armor specifically designed to protect the wearer's vital organs from injury caused by firearm projectiles” (“How Bulletproof Vest is Made”). Many people prefer calling them “bullet-resistant vests” because the person who wears the vest is not completely safe from a bullet. There are many components that go into making a vest. A vest-shaped sheet of advanced plastic polymers, called a panel, is composed of many layers of Kevlar or Spectra Shield. While, the layers of woven Kevlar are sewn together using Kevlar thread, the non-woven Spectra Shield is coated and bonded with resins. An example of a possible resin is Kraton. It is then sealed between two sheets of Polyethylene film. The panel is placed inside of a fabric shell that is made from nylon or a blend of cotton and polyester. Some bulletproof vests add nylon padding for extra protection. Many bulletproof vests contain built-in pouches that are used to hold plates. These plates are made from either ceramic bonded to fiberglass or metal. In order to keep the vest on, the sides are connected with elastic webbing, cloth, metallic buckles, or velcro closure...
SWAT tactics have come a very long way since its creation in 1967 in Los Angeles, California. Every day SWAT teams are being called to dangerous scenarios in which they are trained to handle to keep everyone involved in the scenario safe, including the offender. From starting off at a basic police academy, a SWAT member blossoms into one of the most mentally, and physically tough officers within the lines of Law Enforcement. It takes patience, and lots of training to officially be on a SWAT team, but if you achieve such status you will be respected by many. SWAt teams deal with many situations. Most people do not realize the mass amount of calls they receive every year, and with the amount that they get, not all calls end up being a shooter. A lot of times these calls they receive are not for an active shooter but can be as complex as a person threatening to commit suicide which they take such calls very seriously. Handling these calls is not a walk through the park so that is why all swat teams train on a regular basis, and stay up to date with the most modern tactics and techniques to get their job done as best as possible.
Personal security of soldiers in armed combat involved developing methods of protecting the body from mortal wounds, thus increasing the survivability rate of one’s forces. The solution for Hittites was body amour and shields. The Hittites body amour was composed of overlapping bronze scales that deflected or trapped arrows. In addition, the Hittites wore bronze helmets as well to protect the head against arrows and blows from axes. For additional protection in close combat, especially from edged weapons, a shield was used to parry attacks. The Hittites favored two types of shields, the circular and figure eight, believed to be utilized by the Chariot squad. Both were lightweight, constructed of wood and overlaid with leather (Bryce (Bryce Trevor, 2007, p. 19).
Armor was the main use of protection in the middle ages. One of the most important parts about combat if you didn't have armor then you was vulnerable in combat. Armor has evolved throughout the middle ages from an animal pelt to iron, steel and bronze. “Through the centuries, such materials as animal skins, bronze, and steel have been used to make armor. Until the invention of firearms, increasingly effective armor was designed to match advances in weapons”. (“Medieval Warf...
The clothes worn with a knight’s suit of armor gave both comfort and protection to the knight. The parts of a medieval knight's suit of armor were a complex series of garments, chain mail and iron plate. The pieces of a knight’s suit of armor covered the most exposed parts of a knight's body. Knights would wear under clothes consisted of a linen under-shirt and linen under-pants, woolen stockings covered the legs. A knight's underclothes were important. It prevented the armor from chafing the knight’s skin. A padded garment known by various names such as aketon, consisted of a quilted coat which was either sewn or stuffed with linen or even grass. This served as padding for additional armor worn over the top.

The topic in which that I will be talking about in this essay is about the development of the military helmet from the past, on towards the current time and the future of the helmet’s and how feasible the development of the future design will be. The development of the military helmet has always been a large impact on the survivability of the infantry unit, being in which the design’s had to always consider the possible advantages and risks that maybe brought to the infantry soldiers. First sightings of the use of military helmets can be dated back all the way to the medieval era, but as of recent times the dangers that the infantry has been exposed to has increased the need of a better designed helmet which would allow better mobility and protection. This is the reason in which I have focused from the time period of WWI. The research question that I had used to further this investigation is “How has the development of technology allowed for the advancement of military helmets?”, My research is meant to show how helmets have developed
Crime is everywhere and it takes a special group or team of people to stop it, or make crime less tempting to do. The main job of police and security officers is to maintain justice, order and peace. In order to keep peace police officers must go through an academy that will prepare them for most situations that they will have to face later on in their career. Some situations require a more intense way to solve a problem such as using force or putting the perpetrator in fear so they will give in to what the police are asking. In some cases the peretrator(s) are too volatile or risky for the basic trained police officer, so the swat team must be used. The swat team unit or “special weapons and tactics” is a higher trained police force. It is a select group of officers that have been through more training and more experience than the average cop. Without the police or security civilians may not feel as safe as they do now when they are walking in the streets or going to a public event. For the people who want to be part of such a unit and are willing to put people before themselves will need to know what it takes to be a police officer.
