getting the PASGT until 1988. Accessories Various add-on accessories were developed for the PASGT helmet, including a helmet mount assembly to attach night vision goggles and a riot protection helmet visor mount. Replacement The PASGT helmet was replaced in U.S. military service by the Lightweight Helmet for the U.S. Marine Corps and the Modular Integrated Communications Helmet by the U.S. Army, which was in turn replaced by the Advanced Combat Helmet. Both were eventually replaced by the Enhanced Combat Helmet (ECH) around 2012 and 2014. The PASGT system is still used by some U.S. allies and still sees some continued limited use in the U.S. military as of 2017, serving as one of the options available for sailors assigned to duty aboard U.S. Navy vessels. Vest The PASGT vest was the U.S. military's standard upper torso body armor from the mid-1980s up until the early 2000s, when it was replaced by the Outer Tactical Vest of the Interceptor body armor system. The PASGT vest replaced the M-69 Fragmentation Protective Body Armor nylon vest used by the Army, and the M-1955 Fragmentation Protective Body Army nylon and doron plate vest used by the Marine Corps. The PASGT vest used Kevlar for the first time in the U.S. military's body armor, unlike the ballistic nylon that was used in the models of body armor that preceded it. While generally incapable of stopping rifle bullets, the PASGT vest provided better protection against shrapnel and reduced the severity of injuries from small arms fire when compared to the M-69. Despite its ability to stop pistol rounds, including 9×19mm Parabellum FMJ, the vest was only ever designed or intended to stop small fragments without injury to the user. The PASGT vest weighs approximately , a small increase over the previous model. Based on testing conducted for the Brass Fetcher Ballistic Testing Company, former ARDEC research engineer John Ervin stated that the PASGT vest is equivalent to NIJ level II or IIA protection: able to stop multiple 124-grain 9x19mm FMJ pistol rounds to its main torso panels (front and back), but susceptible to several closely spaced rounds or shots to the thin neck and shoulder panels. Another independent test, featured in the magazine GunNews, claimed that the PASGT vest could stop .357 Magnum Federal 125 grain JHP, .357 Magnum S&W 158 grain JSP, 9mm Federal 115 grain FMJ, and 9mm +P+ Corbon 115 grain FMJ at
