that use or resemble the M35 Stahlhelm. The U.S. Army's 1980s and 1990s era Kevlar Personnel Armor System for Ground Troops Helmet was sometimes called the "Fritz helmet" for its resemblance to the Stahlhelm. The U.S. Army and Marines have continued to use a design akin to the PASGT helmet with the MICH TC-2000 Combat Helmet and Lightweight Helmet, respectively. The Chinese People's Liberation Army soldiers still used M1935 helmets which were captured from the Chinese Nationalist Army during the Chinese Civil War until the 1970s. Since 2012, El Salvador's Policia Nacional Civil use a navy/indigo blue-coloured helmet that strongly resembles the Stahlhelm; this helmet is used by some members of the riot-control unit and rarely used by the Police's assault teams. Variants The different Stahlhelm designs are named for their year of introduction. For example, the Modell 1942 which was introduced in 1942 is commonly known as M1942 or simply M42. Here, they are referred to by their M19XX names. M1916 and M1917 The Stahlhelm was introduced into regular service during the Verdun campaign in early 1916. The M1916 design had side-mounted horn-like ventilator lugs which were intended to support an additional steel brow plate or Stirnpanzer, which saw limited use only by snipers and trench raiding parties, as it was too heavy for general use. The shell came in different sizes, from 60 to 68, with some size 70s reported. Helmet weight varied from 0.98 kg to 1.4 kg, depending on shell size. The suspension, or liner, consisted of a headband with three segmented leather pouches, each holding padding materials, and leather or fabric cords that could be adjusted to provide a comfortable fit. The one-piece leather chin strap was attached to the shell by M1891 chinstrap lugs, the same kind used in the Pickelhaube helmet. The M1916 design provided excellent protection. Reserve Lieutenant Walter Schulze of 8th Company Reserve Infantry Regiment 76 described his combat introduction to the helmet on the Somme, 29 July 1916: ... suddenly, with a great clanging thud, I was hit on the forehead and knocked flying onto the floor of the trench... a shrapnel bullet had hit my helmet with great violence, without piercing it, but sufficiently hard to dent it. If I had, as had been usual up until a few days previously, been wearing a cap, then the Regiment would have had one more man killed. But the helmet was
