Personnel Armor System for Ground Troops

The Personnel Armor System for Ground Troops (PASGT, pronounced PAZ-gət) is a combat protective ensemble developed in the late 1970s by the United States. Introduced to frontline service in the early 1980s, the system consisted of a helmet and vest, both constructed primarily from Kevlar and was intended to deliver superior ballistic and fragmentation resistance compared to the steel M1 helmet and earlier nylon vests.
