The 7.62 × 63 AP mm (.30-06 Springfield) cartridge was frequently employed by American forces throughout World Wars I and II, as well as the Korean War.Level 4 body armor can withstand the following types of ammunition: Several consecutive hits from a rifle can be fatal. The kinetic energy of each shot striking the plate, on the other hand, steadily degrades it. It will readily deflect conventional ammunition’s impact. The NIJ Level 4 category includes combat armor capable of withstanding at least one hit from a 7.62 armor-piercing bullet from a Springfield rifle. In the armed forces around the world, such plates are used in body armor to equip infantry units, which during combat operations are more at risk of being hit by sniper fire than others. The customer must select between two options: a cheaper but heavy option or a lighter but significantly more costly one. However, they are around 20% lighter and considerably more comfortable to wear.Īll three types of level 4 armor are available for civilians nowadays. Hence the higher price of ceramic body armor. Armor plates made of boron and silicon carbides are technologically more difficult to produce than aluminum oxide. These three materials are characterized by approximately the same impact resistance, but differ greatly in weight, complexity of manufacture, and cost. Plates are formed of three substances in industrial production: Level 4 armor plates are composed of advanced ceramics that can stop a 7.62 mm rifle bullet without causing major injury to a person wearing the body armor. Aluminum oxide is substantially cheaper to make, body armor more accessible to the general public, but there is a downside for it is extra weight cooperating to the other ceramic materials. To give a comparable amount of protection, they are thicker and heavier. The molecules are structured in a cross pattern, which also helps distribute the external tension evenly over the surface.Īluminum plates, on the other hand, have a lower tensile strength. Aluminum oxide, on one hand, does not have a hexagonal ceramic structure. Any point hit on the surface is extended throughout the whole armor plate as a result of this property, rapidly extinguishing the kinetic energy of the impact. In this case, one such thread stretches the entire length of the plate. Level 4 ceramic plates are made up of hexagonal ceramics with long molecular filaments. Even if the bullet does not pierce the plates, the force of the impact is such that it leaves bruises on the body, and even breaks the ribs. Part of the energy goes to the body of the fighter in it. The impact’s force is felt across the complete body armor system. The kinetic energy of a flying bullet is mostly dampened in contact with the surface of the armor. Level 4 armor plates have a similar principle to Level 3 plates, in which layers of ballistic material (UHMWPE) are pressed together to form a solid block. The vest itself is firmly fixed to the body. This kind of body armor is made up of a combination of rigid ceramic and composite plates that are placed and fastened in specific holders. The fourth level of ballistic protection is the highest in the NIJ classification. Of course, being shot by a sniper is a rare occurrence, but there’s milder armor piercing threats such as 7.62×39 and M855A1 with threats just as dangerous. This level of protection can defend against armor-piercing shots fired by sniper rifles. The highest protection, the most advanced rounds including military threats today is a Level 4 body armor as classified by the NIJ (National Institute of Justice). This product comes with a 5 year warranty.Level 4 body Armor: Maximum Protection Against Most Devastating Threats SafeGuard Armour™ ensures that all products exceed the standards outlined by the NIJ and HOSDB.
