The PASGT or Personnel Armor System for Ground Troops, used by more nations than can be named, swat forces, police, and even paintball teams. This Helmet or K-pot as nick named by US forces, was a welcomed ergonomic, comfortable, light and the best answer the problem of protection. Guess what? its copied from the German Stahlhelm, the iconic helmet of national socialism evil axis forces.
The M15 Adrian helmet At the outbreak of World War I soldiers in the French Army wore the standard kepi cap, which provided no protection against injury. The French staff ordered development of a metal helmet that could protect soldiers from the shrapnel. the Adrian was produced. Compared to the Bodie and Stahlhelm, the Adrian with its top vent, insignia decoration and being made of 3 separate pieces, offered less protection and took longer to produce, however millions were made.
Several nations adopted the Adrian and millions were produced. Belgium, Brazil, China, Greece, Italy (including license-built versions), Japan, Luxembourg, Mexico, Morocco, Peru, Poland, Romania, Russia, Yugoslavia , Serbia, Spain and later U.S.S.R.
The Russian M-36 The M (model, or model) 36 was designed by Aleksandr A. Shvartz, and began production in 1936. Its large front rim and wide flares over the ears provided good protection for the wearer. The M-36 was also fitted with a comb on top, which allowed for ventilation. There were also apocryphal claims that the comb was designed to deflect saber blows and give the helmet some decoration. The Russians used the French Adrian helmet prior to the development of the M-36.
SSH-40. The SSh-40 was the last and most commonly seen in-service helmet used by the Soviet Union during the Great Patriotic War. SSh-40 was only manufactured in three sizes, 1–3. The SSh-40 was supplemented by the SSh-60 and finally replaced by the SSh-68. Like many things Russian and Russian military, comfort was not priority. The ability to produce quickly cheaply and in great numbers took priority. As Stalin once said, Quantity has a quality all of its own.
THE ENGLISH BODIE, or Steel, Mk-I. worn by English forces, and nations of the commonwealth. The Bodie was also used by American forces in WW1, they called it the Tommy Tin. A design patented in 1915 by John L. Brodie of London offered advantages over the French design. It was constructed in one piece that could be pressed from a single thick sheet of steel, giving it added strength, easy, quick and inexpensive to produce.
THE STAHLHELM The design of the Stahlhelm was carried out by Dr. Friedrich Schwerd of the Technical Institute of Hanover in early 1915 studies done on injuries and fatalities from shrapnel and modern warfare hazards, led to this design that provides the best protection possible. Later the Stahlhelm became a symbol for Nazi Germany however the design of modern Kevlar helmets are based off the stahlhelm design.
