K is the revision number of the standard.) MIL-DTL-46177 is an older, now-replaced standard for a high hardness steel RHA. [4] It specifies a harder steel that is nearly identical to AR500 in terms of tensile and yield strength. [5] The Brinell hardness of AR500 is in the 477-534 range. MIL-DTL-46100E specifies a steel of identical hardness. [3]
For example, the T-64 turret had a layer of ceramic balls and aluminum sandwiched between layers of cast steel armour, [10] whilst some models of the T-72 features a glass filler called "Kvartz". The tank glacis was often a sandwich of steel and some low density filler, either textolite (a fibreglass reinforced polymer) or ceramic plates. [11]
The two metallic plates in the NERA sandwich are made of steels of varying hardness and thickness. Depleted uranium plates have also been tested. [7] Rubber and plastic were initially used as the inner non-metallic material, but modern materials now include foam, nylon, polycarbonate, glass, elastomer and more energetic materials such as glycidyl azide polymer (GAP).
Forerunner of the great helm. The enclosed helmet covered the entire head, with full protection for the face and somewhat deeper coverage for the sides and back of the head than that found on previous types of helmets. It was developed near the end of the 12th century and was largely superseded by the true great helm by c. 1240. Great helm
The Improved Outer Tactical Vest (IOTV) in MultiCam, as issued to United States Army soldiers. A bulletproof vest, also known as a ballistic vest or bullet-resistant vest, is a type of body armor designed to absorb impact and prevent the penetration of firearm projectiles and explosion fragments to the torso.
An IDF Caterpillar D9 armored bulldozer equipped with slat armor surrounding its driver's cab. Slat armor (or slat armour in British English), also known as bar armor, cage armor, and standoff armor, is a type of vehicle armor designed to protect against high-explosive anti-tank (HEAT) attacks, as used by anti-tank guided missiles (ATGMs) and rocket-propelled grenades (RPGs).
After initially using IBA as their main body armor system, the U.S. Marine Corps developed a completely new armor system, the Modular Tactical Vest, which was their primary body armor system in Iraq. On September 25, 2006, the Marine Corps announced that Protective Products International won a contract for 60,000 new Modular Tactical Vests (MTV ...
There was a 150-year period in which better and more metallurgically advanced steel armor was being used, precisely because of the danger posed by the gun. Hence, guns and cavalry in plate armor were "threat and remedy" together on the battlefield for almost 400 years. By the 15th-century, Italian armor plates were almost always made of steel. [12]
