History
Helmets are among the oldest forms of
Military use of helmets declined after 1670, and rifled
World War I and its increased use of artillery renewed the need for steel helmets, with the French Adrian helmet and the British Brodie helmet being the first modern steel helmets used on the battlefield,[7][8] soon followed by the adoption of similar steel helmets, such as the Stahlhelm[9][10] by the other warring nations. Such helmets offered protection for the head from shrapnel and fragments.
Today's militaries often use high quality helmets made of ballistic materials such as Kevlar and Twaron,[11] which offer improved protection. Some helmets also have good non-ballistic protective qualities, against threats such as concussive shock waves from explosions.[12][13]
Many of today's combat helmets have been adapted for
Beginning in the early 20th century, combat helmets have often been equipped with helmet covers to offer greater camouflage. There have been two main types of covers—mesh nets were earlier widely used, but most modern combat helmets use camouflage cloth covers instead.
By the late 20th century, starting in the 1970s and 1980s, new materials such as Kevlar and Twaron began replacing steel as the primary material for combat helmets, in an effort to improve weight reduction and ballistic protection, and protection against traumatic brain injury. This practice still continues into the 21st century, with further advancement and refinements in the fibers used, design and shape of the helmet, and increased modularity. Early helmet systems of this new design are the American PASGT, the Spanish MARTE, the Italian SEPT-2 PLUS, and British Mk 6.
Padding
Cushioning is used to negate concussive injuries. Researchers at the Lawrence Livermore National Laboratory published a study in 2011 that concluded that the addition of 1⁄8 inch (3.2 mm) of cushion decreased the impact force to the skull by 24%.[14]
