At this very moment armed forces are fighting for our freedom overseas. These brave soldiers go out everyday risking their lives for us. This is not a safe job numerous incidents bring these people to harm, but there is a way that chemistry has helped protect those at war. This is by the invention of the bulletproof vest. This vest can stop bullets from entering someone’s body with only leaving bruises behind. Somewhere else in the world a fire is burning down a house with people inside. Firefighters will be called to put out the fire and help these innocent people. The equipment they wear helps protect them from serious burns and injuries allowing them to do their job. The bulletproof vest and firefighters uniform cannot be made unless …show more content…
The flak jacket provided protection primarily from ammunitions fragments and was ineffective against most pistol and rifle threats. Flak jackets were also very bulky. Bulletproof vests have come a long way since their silk and flak days. Developed at DuPont in 1965, the high strength material was first commercially used in the early 1970s as a replacement for steel in racing tires. In the late 1970s it was discovered that Kevlar would make a good material for body armor. Kevlar soon became manufactured. Kevlar soon became used in body armor all over the world and is still seen being used today.
Kevlar is constructed of manmade fibers known as aramids. It belongs to a class of polymers. The polymers work just like gauze, but at a microscopic level. The basic unit of a polymer is a chain. Each one of the chains is made of millions of “monomers” that are linked to each other by chemical bonds. The monomers are long and rod-like. With Kevlar, the monomers link with there own chains and cross-link to monomers in other chains. The more Kevlar cross-links, the harder it becomes to separate the chains from each other. The cross-linking between intermolecular and intramolecular molecules is what gives Kevlar the strength five times that of steel with a flexible strength-to-weight ratio. Typically Kevlar is spun into ropes or fabric sheets that can be used as an ingredient in the composite material components. When you make a thick layer of Kevlar, it is able to
War is something that can change the very principles of a person, it can change a person and leave multiple effects that can last for their entire life. The sniper is fighting in a civil war where friends and family can turn into enemies at a moment's notice. The fight is between the Republicans and the Free Staters, the protagonist is a sniper for the Republicans. Throughout the story, we go into the state of mind of the main character and learn some ramifications that he gained in the war. The text, “The Sniper” by Liam O’Flaherty shows us the physical and psychological results of war, that happens to people.
In this essay I will describe the many requirements and expectations set forth in the army's AR670-1. I will describe the importance of obedience to it and cite many of it's detailed descriptions. I am writing this essay because I failed to meet the standards asked of me me by both these regulations, and my leadership. I accept the responsibility of my actions and will not let my failure recur, nor will I let my fellow soldiers repeat my mistake. Since my failure was in regards to grooming or personal additions to uniform, I thought it would be pertinent to cover these subjects most thoroughly, If any additional information is required of me I will add on to this.
The 4th Armored Brigade Combat Team (ABCT) has a proud history of accomplishments. It has served in the wars in Iraq and Afghanistan. Historically, the morale across the brigade was high; leaders took care of their Soldiers, and all of them did their best to train them, accomplish missions successfully, and support them in any way. The 4th ABCT HQ, as well as each of the battalions, were highly efficient and effective, and most of them were jubilant to be part of the brigade. Three years ago, one of the best maneuver brigades in FORSCOM was the 4th ABCT. The brigade had focus; leaders and soldiers were dedicated, and there was a strong work ethics. However, the 4th is facing some challenges ahead that are going to make difficult to reach its full potential. Amongst several leadership problems, there is a major one. There is not an organizational vision in the brigade, and if there is, it is unclear and poorly evident.
The article "Beating the Heat" by Stephanie Warren Drimmer, is about two high school students who saw the suits that fire fighters wear wore fail, and as a result, 19 firefighters died. They decided to research and improve how firefighting suits are made. They discovered that designs for firefighting suits are nearly 40 years old. They discovered that the material the suits were made of would disintegrate at only half the temperature of a rapid-moving fire.
military’s vast experience in responding to and managing casualties from IED and/or active shooter incidents and from its significant investment in combat casualty care research into the civilian first responder environment” (DHS, First Responder Guide. 2015). In order to improve safety in response to terror events, especially those classified as international terrorism it will require that first responders to further prepare for a vast variety of potential threats. The focus of this increased preparation should not only regard the safe and effective responses of first responders to all potential hazards caused by a terrorist event; but should also include the improvement of first responder’s connections to their communities, the gathering of intelligence, information sharing, and realizing their role in domestic defense of the United States of America.
Validity claims are deriving from the potentially unbalanced and discriminative approaches to determining ones capabilities through and within the City of Lakewood’s firefighter program. Claims of standardized equipment restricting the physical capabilities of one’s movement is effecting ones results, however, fire retardant boots and gloves are required for the protection of firefighters during the course of duty and should not be compromised. The main purpose is to ensure the individuals are mentally prepared, conditionally effective, and supplied with the abilities to endure prolonged periods of exposure to highly intensified situations. Although such requirements are demanding, strenuous and potentially hurtful, it is extremely vital that when delivering products of public
The Army White Paper: The Profession of Arms (2010) highlights the importance of understanding the roles inherent of the Human Resources Sergeant. A Human Resource Sergeant is known for being both a profession and a professional culture. This profession is required to balance responsibilities with leadership and mission requirements in an effective, efficient and timely manner.
A Profession of Arms. It is a title that the United States Army currently holds. A Profession that is uniquely separates us based on the lethality of our weapons and operations. Many factors are involved that make what we do in the Army a Profession and not just a job or an occupation. To maintain this idea that what we do is a Profession takes understanding what a Profession is, a tenuous balance by leadership and the culture of the professionals within. As a Human Resource Sergeants, we do not carry the Arms that grant us our lethality, yet we still have a vital role within this Profession of Arms.
Bulletproof vest are made of either ceramic materials, layered Kevlar, metal plating, tensil liquids or a variety of other materials depending on the calibre of the weapon being shielded against. Small hand guns with low power will be effectively protected against by vests made of Kevlar fabric while higher calibre weapons will require more protection. Hand grenades and shotguns may require metal plated vests. (“What is a Bulletproof made of”).
In the article “Know the Smells and Warning Bells of WMD”, the author, John Linstrom’s principal point is that the fire departments should better prepare to respond to incidents involving weapons of mass destruction (WMD). Historically, explosive or WMD incidents were handled by law enforcement, while fire assumed a support role, but with increased terroristic occurrences, firefighters have been finding themselves in situations where they have been first on scene. Mr. Linstrom stresses that firefighters need to be mindful of the threat of explosives and WMD’s when responding to incidents (Linstrom, 2004). Firefighters need to familiarize themselves with terrorist tactics and beware of potential high-risk
Meaning and purpose can be defined depending on the reader and the author that is defining it. The meaning and purpose of any form of literature is the main point of the piece of work, why it was created and what the author wants the reader to understand or get from his or her work. As for the movie Full Metal Jacket, the director, Stanley Kubrick, wanted to have a combination of comedy as well as a sense of realization when it comes to a soldier becoming a marine and what it takes to be one. The characters throughout the movie each show a different way of understanding and dealing with the problems that they had to quickly overcome.
Having an armor is a must for every soldiers in the battlefield. The soldiers will never know what will happen to them. That is why an armor is critical for them because it serves as their first layer of protection during their time the battlefield. In general, an ideal armor must be solid, strong, and comfortable to wear. On the other hand, an armor must be lightweight too because the soldiers will not wear an armor that drain their energy. Also, if possible, a flexible or bendable material can be one of the main composition for the armor. It will increase the comfortability of the armor for the soldiers. So that, they can perform better because they have a better equipment on them.

What is a profession? First and foremost let’s look at how we can define a profession from a general point. A profession is an occupation requiring specialized knowledge and often long and intensive academic preparation. Profession doesn’t mean only to be perfectly prepared on the basis of theoretical aspects, but to meet the strict criteria as well. A good professional should be a leader and leadership means solving problems. Leaders can be assessed according to the amount of resolved problems. Everybody has a tendency to be successful, in trying this; a successful leader has to be confident in his decisions. It follows from that, that generally we can consider the leader as an expert, a matured personality, somebody who meets the high
The greatest threat facing the Modern Fire Service is the rate at which firefighters are dying in the line of duty. Excluding the terrible event of 9/11 that occurred in 2001 that forever changed the dynamics of the emergency response services1, firefighter deaths have averaged around 100 fatalities each year for the since 1990. This unacceptable rate of firefighter deaths has found its way to be a benchmark in the industry. The problem is that the benchmark should be zero firefighter deaths while on duty and every year that there is a fatality is a year that the fire service has failed its members. The number one cause of firefighter related deaths yearly is proven to be medical, stress, or overexertion related fatalities2. All of these causes of firefighter deaths can be avoided with implementation of training and awareness.
