Personnel Armor System for Ground Troops (PASGT; pronounced pass-GET) is a combat helmet and ballistic vest that was used by the United States military from the early-1980s until the mid-2000s, when the helmet and vest were succeeded by the Lightweight Helmet, Modular Integrated Communications Helmet, and Interceptor body armor.

In the U.S. military, the PASGT helmet was most commonly known by its wearers as simply the "Kevlar". The nickname has since been adopted for usage with other helmets. The PASGT helmet was also referred to by its wearers in the U.S. military as the "K-pot", similar in name to the colloquial nickname "steel pot" for the steel M1 helmet, which was in widespread U.S. military usage from the 1940s, to the 1970s, including the Vietnam War. The PASGT helmet was also, but less commonly, known by its wearers as the "Fritz" helmet for its resemblance to the Stahlhelm, which was the standard helmet used by the German military forces in the First and Second World Wars.

The PASGT helmet is also used by various SWAT teams, where it is often black in color, with or without covering. It is also used by United Nations Peacekeeping forces where it is often painted United Nations blue to match the colors of the United Nations flag.

The PASGT helmet was developed after the Vietnam War in 1975 and replaced the steel M1 helmet in U.S. military service during the 1980s. It first saw use in combat in 1983 during Operation Urgent Fury in Grenada, and 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. Soldiers stationed in Alaska were some of the last to receive the helmets, some not getting the PASGT until 1988.
