Enhanced Combat Helmet (United States)
The Enhanced Combat Helmet (ECH) is a combat helmet designed in conjunction of a joint program of the United States Marine Corps and United States Army to replace the current combat helmets in use by the U.S. Army, Air Force, Navy, and Marines. Although similar in shape of the Advanced Combat Helmet and its predecessor the Modular Integrated Communications Helmet, the ECH instead is constructed using thermoplastics instead of the ballistic fibers used on the previous generation combat helmets. It is planned to be succeeded by the Integrated Head Protection System. Design The ECH's profile is very similar to the Advanced Combat Helmet (ACH) but is thicker; they can be differentiated from the ACH by the different chinstrap. The ECH helmet's shell is made of an ultra-high-molecular-weight polyethylene (UHMWPE) material. The helmet provides 35% better protection against small-arms fire and fragmentation than the Advanced Combat Helmet, and it protects against certain rifle projec ...

Combat Helmet
A combat helmet or battle helmet is a type of helmet. It is a piece of personal armor designed specifically to protect the head during combat. Modern combat helmets are mainly designed to protect from shrapnel and fragments, offer some protection against small arms, and offer a mounting point for devices such as night-vision goggles and communications equipment. History Helmets are among the oldest forms of personal protective equipment and are known to have been worn by the Akkadians/Sumerians in the 23rd century BC, Mycenaean Greeks since the 17th century BC, the Assyrians around 900 BC, ancient Greeks and Romans, throughout the Middle Ages, and up to the end of the 17th century by many combatants. Their materials and construction became more advanced as weapons became more and more powerful. Initially constructed from leather and brass, and then bronze and iron during the Bronze and Iron Ages, they soon came to be made entirely from forged steel in many societies afte ...

Combat Helmets Of The United States
Combat ( French for ''fight'') is a purposeful violent conflict meant to physically harm or kill the opposition. Combat may be armed (using weapons) or unarmed ( not using weapons). Combat is sometimes resorted to as a method of self-defense, or can be used as a tool to impose one's will on others. An instance of combat can be a stand-alone confrontation or a small part of a much larger violent conflict. Instances of combat may also be benign and recreational, as in the cases of combat sports and mock combat. Combat may comply with, or be in violation of local or international laws regarding conflict. Examples of rules include the Geneva Conventions (covering the treatment of people in war), medieval chivalry, the Marquess of Queensberry rules (covering boxing) and several forms of combat sports. Hand-to-hand combat Hand-to-hand combat (melee) is combat at very close range, attacking the opponent with the body ( striking, kicking, strangling, etc.) and/or with a melee we ...

Head Gear System
The Head Gear System (HGS) is a future headgear ensemble under development by the U.S. Army. HGS attempts to integrate head protection against ballistics, fragmentation, blast, blunt force, flash heat, and noise into a single lightweight, modular, scalable headgear system. Program Executive Office (PEO) Soldier is working to develop a Soldier-centric Head Gear System (HGS) that provides ballistic and traumatic brain injury protection as well as face, neck, and hearing protection. The HGS also will incorporate integrated sensor inputs along with display hardware and software for increased situational awareness. The system will address technology gaps identified by the Capabilities Development Integration Directorate of the Army's Training and Doctrine Command. Design The headgear system will be based on a modular platform for which protection levels and system enhancements can be added or removed based on mission requirements and/or predetermined threat assessments. HGS will be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philippine National Police
The Philippine National Police ( fil, Pambansang Pulisya ng Pilipinas, acronymed as PNP) is the armed national police force in the Philippines.

DILG, on the other hand, organizes, trains and equips the PNP for the performance of police functions as a police force that is national in scope and civilian in character. The PNP was formed on January 29, 1991, when the Philippine Constabulary and the Integrated National Police were merged pursuant to Republic Act 6975 of 1990.

United States Navy SEALs
The United States Navy Sea, Air, and Land (SEAL) Teams, commonly known as Navy SEALs, are the U.S. Navy's primary special operations force and a component of the Naval Special Warfare Command. Among the SEALs' main functions are conducting small-unit special operation missions in maritime, jungle, urban, arctic, mountainous, and desert environments. SEALs are typically ordered to capture or to kill high level targets, or to gather intelligence behind enemy lines. All active SEALs are members of the U.S. Navy. The CIA's highly secretive and elite Special Operations Group (SOG) recruits operators from SEAL Teams, with joint operations going back to the MACV-SOG during the Vietnam War. This cooperation still exists today, as evidenced by military operations in Iraq and Afghanistan. History Origins Although not formally founded until 1962, the modern-day U.S. Navy SEALs trace their roots to World War II. The United States Military recognized the need for the covert reconnaiss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polyvinyl Butyral
Polyvinyl butyral (or PVB) is a resin mostly used for applications that require strong binding, optical clarity, adhesion to many surfaces, toughness and flexibility. It is prepared from polyvinyl alcohol by reaction with butyraldehyde. The major application is laminated safety glass for automobile windshields. Trade names for PVB-films include KB PVB, Saflex, GlasNovations, Butacite, WINLITE, S-Lec, Trosifol and EVERLAM. PVB is also available as 3D printer filament that is stronger and more heat resistant than polylactic acid (PLA). Applications Automotive and architectural Laminated glass, commonly used in the automotive and architectural fields, comprises a protective interlayer, usually polyvinyl butyral, bonded between two panels of glass. The bonding process takes place under heat and pressure. When laminated under these conditions, the PVB interlayer becomes optically clear and binds the two panes of glass together. Once sealed together, the glass "sandwich" (i.e., lamin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lightweight Helmet
The Lightweight Helmet (LWH), also known as the Lightweight Marine Corps Helmet or Lightweight Marine Helmet, is an armored helmet that is used by the United States Marine Corps and U.S. Navy. It is the U.S. Marine Corps' replacement for the PASGT combat helmet and is derived from the Modular Integrated Communications Helmet. History As it is nearly identical to untrained eyes in shape to the PASGT, outside the Marine Corps it is still called the Fritz helmet or K-pot (due to its resemblance to the German Stahlhelm). Though heavier than the United States Army's Advanced Combat Helmet, its larger size also offers more protection and is lighter than the PASGT. Featuring a four-point retention strap system (compared to the two-point retention of the PASGT) and redesigned liner, it is considered more comfortable than the PASGT. The LWH was designed in 2003 and entered service later that year. It completely replaced the PASGT in USMC service by 2009. The LWH was made by the Gentex C ...
