The Personnel Armor System for Ground Troops (PASGT), is a combat helmet that was used by the United States military from the mid-1980s until the mid-2000s, when the helmet was succeeded by the Lightweight Helmet and Modular Integrated Communications Helmet. In the U.S. military, the PASGT helmet was most commonly known by its wearers as simply, the Kevlar. The PASGT helmet was also, but less commonly, known by its wearers as the Fritz helmet, for its striking resemblance to the Stahlhelm helmet, which was the standard helmet used by the German military forces in the First and Second World War.
