Definition of bulletproof helmet
Bulletproof helmets are equipment that can absorb and dissipate the energy of the warhead, prevent penetration, reduce blunt trauma, and effectively protect the human head.
Bulletproof helmets are divided into three categories according to the material of the helmet shell: metal, non-metal, metal and non-metal composite. In addition to the old-fashioned steel helmets, the main materials for making bulletproof helmets are UHMWPE fiber and aramid. UHMWPE fiber helmets are lighter.
Bulletproof helmet styles
Bulletproof helmets have undergone many years of development and evolution in the history of the world. From the beginning of the steel helmet to the use of high molecular weight polyethylene fibers and aramid polyamide materials, the styles of intermediate bulletproof helmets have undergone countless changes, but among them The most representative helmets are still in use, mainly MICH, FAST, PASGT.

Bulletproof helmets have undergone many years of development and evolution in the history of the world. From the beginning of the steel helmet to the use of high molecular weight polyethylene fibers and aramid polyamide materials, the styles of intermediate bulletproof helmets have undergone countless changes, but among them The most representative helmets are still in use, mainly MICH, FAST, PASGT.
Next, we will introduce these three styles of bulletproof helmets separately.
MICH Bulletproof helmet
1. Style introduction
MICH bulletproof helmet (Moduler Integrated Communications Helmet) is a modular integral personal wireless communication helmet, which is mainly used for special forces as one of the SPEAR series equipment. MICH is shallower than the PASGT (Individual Armor System for Ground Soldiers) helmet, has no brim, and is bonded with a variety of Kevlar fibers. MICH uses a new seven-padded suspension system. The padding consists of two foam materials that deform to fit different head shapes for better wearing comfort. The suspension system is attached to the inside of the helmet via a series of Velcro fasteners, secured using four-point chin straps.
Since 2001, MICH has been assigned to the special forces of the US Special Command, the Marine Corps Reconnaissance Force, and some units of the 82nd Airborne Division.
A total of about 200,000 helmets are equipped with U.S. troops. At the same time, the MICH helmet has been used in the U.S. Army's Land Warrior system, and will replace the PASGT as the U.S. Army's standard helmet in the future.
2. Development history
The Michigan was originally part of a line of combat helmets for the U.S. Army Special Operations Command as replacement PASGT helmets and various non-ballistic skateboard, bicycle, and whitewater "collision" helmets available only in these units. Development began in 1997 and was released by the U.S. Army Soldier Systems Center in January 2001.
Mich developed mainly because the heavily protective PASGTs were replaced by special forces helmets, as they were lighter, more comfortable, fit better, and were made of plastic, making them easier to attach accessories, especially Yes. Night vision equipment and communication headsets. The light weight and non-ballistic nature of these helmets allow additional attachments to be installed without undue pressure on the neck, or require the installation of night vision mounting brackets through Kevlar drilling, which can damage if not precise The protective power of a Kevlar helmet. Inevitably, operators were injured and killed by entering the unforgiving environment of close-quarter warfare, especially the 1993 war environment, with their totally inappropriate plastic helmets. The Battle of Mogadishu in which at least one of the Delta Force operators (SFC Shughart or Gordon was said to have been shot in the head by a rifle) was killed. While ballistic helmets at the time were unable to withstand rifle fire in close combat, But it inspired the U.S. Army to create a new helmet to better protect special forces in direct action missions while offering the weight and modularity they had hoped for, keeping them from using the PASGT in the first place.
A tentative stop gap solution is provided in the rbr helmet, it's hard to find information about it, but seems to be from France. Spectral helmet; it is particularly similar to the Canadian CG 634, which is a derivative. Meanwhile, development of a specialized helmet was underway under the Spear Program, which eventually produced Michigan in the late 1990s. and provides three cuts to allow operators to choose balance, protection and weight to suit their preferences and mission profile. While it doesn't completely replace plastic crash helmets, it almost completely replaces helmets in direct-action missions where operators are likely to suffer head injury from debris, impact or bullets. Initially, it was used almost exclusively by SOCOM and some units closely associated with them; however, the U.S. Army later decided that the improvements brought by the Mich, which was lighter, taller, and more rimless than the PASGT helmet, were worthwhile across the organization Scope and begin releasing examples to the entire Army as a more cost-effective solution to retooling the entire Army.
To date, the Michigan State and its derivatives, the Advanced Combat Helmet and Enhanced Combat Helmet, have completely replaced the active-duty U.S. Army's PASGT and have been in use by all branches of the U.S. military to at least some degree.
The U.S. Marine Corps evaluated the Mich in their search for a PASGT replacement, but chose a helmet that retained the PASGT's silhouette but was lighter, called the Lightweight Helmet, which included improvements to the Michigan, such as pads and retention systems.

FAST Bulletproof helmet
1. Style introduction
The full name of the FAST bulletproof helmet is Ops-Core Future Assault Shell Technology Helmet, which is a combat helmet developed by the US Army and produced by Ops-Core, a Gentex subsidiary. The helmet is designed to provide comfort for special operations operators while also providing basic ballistic protection. FAST helmets are currently widely used in special forces and special police units in various countries. In addition, the FAST helmet is currently the standard combat helmet of the Norwegian Defence Forces.
2. History
The FAST helmet is the result of research by the U.S. Army Research Institute in conjunction with the U.S. Army Natick Soldier Research, Development and Engineering Center, and the Program Executive Office under the Army Production Technology Program (ManTech). The program also led to the development of other helmets by the U.S. military, such as the Enhanced Combat Helmet.
Its "FAST helmet" name was taken by its manufacturer, Ops-Core, in 2005]. It was first shown to the public at the SHOT SHOW exhibition in 2009, and was immediately adopted by US special operations forces operating in Afghanistan.
3. Features
Compared with conventional military helmets, FAST helmets are 25% lighter in weight. It is also the first helmet to use ultra-high molecular weight polyethylene fibers (UHMWPE), which can effectively block 9mm Parabellum bullets. Firearms shooting. The helmet adopts the suspension system produced by Ops-Core Company, the user can easily adjust the helmet loose or tight, and achieve the best comfort. FAST helmets are equipped with ARC rails on the left and right sides for users to install flashlights, anti-noise headphones and communication equipment and other equipment, as well as night vision devices or video recording equipment can be installed on the fixed seat in the center of the helmet through adapters, which is a special Combat adds greater tactical advantage. The devil felt attached to the helmet allows the user to affix the national flag, army or agency of the country to which they belong, as well as relevant identification seals such as call sign and blood type.
Ops-Core's original FAST helmets are available in a variety of different finishes for users to choose from. Liveries currently available include: Khaki, Leaf Green, Army Green, Black, Urban Grey and Multi-Terrain Camo.
In addition, based on its modular design, in addition to being used by the military and police, the civilian version of the FAST helmet without bulletproof function is also widely welcomed by outdoor sportsmen and field workers such as journalists and disaster relief workers.

PASGT Bulletproof helmet
1. Style introduction
The full name of PASGT is Personnel Armor System for Ground Troops. It is a piece of individual equipment assembled by the U.S. military since 1983. The helmet is made of 19 layers of 1500 denier Kevlar 29 Aramid fiber cloth [1], due to its shape Like the M35 steel helmet of the Nazi German army during World War II, it got the nickname (Fritz).
2. Design Features
The PASGT helmet, like the German steel helmet in World War II, pays more attention to protecting the side and rear of the human head. Its sides completely cover the human ears and protrude outward to protect the temples. Designed to be arched upward, the PASGT has 12% more protection area than the old U.S. military M1 helmet, but its rear protection area is still less than that of the German M35 helmet (the sides and rear of the M35 helmet protrude outwards. Side guards, which PASGT does not have), the interior of PASGT is a canvas belt like the M1 steel helmet, but due to the lower center of gravity of PASGT, the wearer can carry it more stably. Although the material of PASGT is composite material Kev pull, but its weight is 1.5 kg, while the M1 helmet made of manganese steel weighs 1.3 kg, which is lighter than the former.
3. Influence
In addition to the military, PASGT helmets are used by special police all over the world. Although some countries do not directly purchase PASGT, they imitate or refer to PASGT in design to become their own domestic composite helmets, such as:
The QGK97 steel helmet equipped by the Chinese People's Liberation Army and the subsequent QGF-02, QGF-03, and QGF-03 have improved the suspension method and shortened the brim.
Developed in France, equipped with SPECTRA helmets for the military and police of France, Canada, Denmark, Austria, Morocco, Malta and other countries.
The M92 combat helmet equipped by the Bundeswehr has its own unique suspension system.
The Japanese Self-Defense Force's 88-type steel helmet has a shorter ear protection than the PASGT, and the lining suspension is changed to a design more suitable for the Japanese head shape.
In 2015, the Korean People's Army was photographed wearing PASGT helmets during the military parade and guards in Panmunjom, which may have been imitated or purchased from China.
