protection against shrapnel and ballistic threats. It meets the 1800 requirement of MIL-STD-662 E. It weighs from (size extra small) to (extra large). Overview The PASGT helmet is typically painted olive drab, though other colors such as tan, grey, and black could also be used. Camouflage was available in the form of cloth helmet covers with varying camouflage patterns, such as woodland, six-color desert, and three-color desert. Some PASGT helmets were retrofitted with newer camouflage colors, such as the Universal Camouflage Pattern and MultiCam. Outside military use, the PASGT helmet has been used by SWAT teams, where it is often painted black. It has also been used by United Nations peacekeepers, where it is often painted United Nations blue. When worn with a helmet cover, the PASGT helmet is often fitted with a band around it that has two light recharging glow patches (sometimes known as "cat eyes") on the rear, intended to reduce friendly fire incidents. These bands are also used to hold vegetation or small personal items, as with the M1 helmet before it. These bands can have names and blood types printed on them to identify the wearer and their blood type in the event of a casualty. In the U.S. Army, PASGT helmets often featured a patch with the wearer's rank insignia on it stitched onto the front, and/or a second patch showing the symbol of the wearer's unit on the sides. The U.S. Marines wore the Eagle, Globe, and Anchor insignia on the front of the helmet as an iron-on transfer, similar to the one worn by Marines on the breast pocket of the BDU. This practice continued with the adoption of the LWH, but fell out of use and was discontinued because the mounting base for night vision devices covered the emblem, and required a hole in the fabric to attach, defacing the symbol. Development The PASGT helmet was developed by the U.S. Army Soldier Systems Center after the Vietnam War during the mid-to-late 1970s. It completely replaced the steel M1 helmet in U.S. military service by the end of the 1980s. It first saw use in combat in 1983 during Operation Urgent Fury in Grenada, became standard issue for the U.S. military in 1985, and completely replaced the M1 helmet for frontline troops by the end of the decade. Army units stationed in Alaska were the last to receive the helmets, some not
