In the early 1980s, military helmets made of steel materials became less and less able to meet the needs of the battlefield. With technological innovation, the U.S. Army began to distribute PASGT military helmets made of Kevlar bulletproof nylon. New military helmets have gradually replaced the M1 military helmets that have been used for more than half a century. In the 1983 US military intervention in Grenada, the first-line US troops have begun to install PASGT helmets. The application of Kevlar bulletproof nylon material provides more effective safety protection measures for officers and soldiers on the front line.
The ASGT military helmet was originally developed by the US Army Natick Research Laboratory. As early as the 1970s, the Natick Research Laboratory had begun to look for lighter materials to make bulletproof vests to meet the needs of the Vietnam War. Compared with the M1 military helmet that has been used for half a century, it can be said that the development and installation of the PASGT military helmet is of epoch-making significance because it opens a new chapter in the history of the world's military helmets.
To introduce the PASGT military helmet, we must first talk about the US military's PASGT system. "PASGT" is the abbreviation of "Personnel Armor System for Ground Troops", and its meaning is "Personnel Armor System for Ground Troops". This system is the individual soldier protection system adopted by the US military from the mid-1980s to around 2000 , Mainly including Kevlar military helmets and anti-fragmentation suits, usually used with the popular ALICE carrying system at that time. To this day, although the PASGT system has withdrawn from the frontline forces of the US military and has been replaced by a new generation of OTV systems, this system is still used for local military training and foreign military assistance to some US military.
"Kevlar" is actually a registered trademark of "para-aramid synthetic fiber". DuPont began to develop this high-strength material in 1965. As early as the early 1970s, Kevlar was used as a substitute for steel wire in racing tires. Under normal circumstances, Kevlar will be spun into ropes or fabric pieces, which can be used directly or combined with other materials.
Because of its high strength and light weight, "Kevlar" materials are currently used in many fields, including vehicle tires, sails, and anti-fragmentation protective gear. Specifically, in the case of the same weight, "Kevlar" material is five times stronger than steel.
The suspension lining inside the PASGT military helmet is made of nylon webbing, but from today’s point of view, this design is still flawed, because soldiers will feel stuffy when wearing this helmet. Therefore, many soldiers Put the plastic foam inside the helmet when wearing this helmet. The suspension system inside the helmet includes a light leather sweat ring (called "doughnut" by American soldiers) and an olive nylon suspension lining. In addition, olive green, sand and gray chin straps can be selected according to different combinations. The specific production information of the helmet is also printed near the inner edge of the helmet.
The helmet suspension, chin strap, suspension screw and sweat ring of PASGT helmet can be replaced and repaired separately. When every soldier gets a PASGT military helmet, he will also get an instruction manual, which will indicate the size of the helmet and some other data.
The PASGT military helmet can be matched with many accessories, among which the night vision device base is the most common one. At the same time, the PASGT military helmet can also be equipped with a transparent anti-explosion mask for use in demonstrations, riots and riots.
Around 2000, the US Army security engineers conducted a test, the subject of which was whether the PASGT helmet would cause a soldier’s neck injury or other accidents due to its heavy weight. Test analysis shows that while the PASGT helmet can prevent head injuries, it is not necessarily related to the soldiers’ neck injuries in motor vehicle accidents.
In the shooting test of the PASGT helmet using MP7, PASGT was penetrated by MP7's 4.6mm bullet. Even the 7.62mm Tokarev pistol can penetrate PASGT at a distance of 7.6 meters. In other words, PASGT is actually unable to withstand any bullet shooting at close range. But it must be noted that, so far, there is no helmet that can effectively protect against bullets at close range.
Today, PASGT helmets have begun to be replaced by more advanced LWH helmets and MICH series helmets, but this upgrade is not the same as PASGT military helmets completely replacing M1 military helmets. Today, many recruits and militia training organizations in the United States still use PASGT military helmets, and the armed forces of some countries or regions that receive US military assistance are also using PASGT helmets.
