The machine that controls the minds of the army
# The US armored helmet has changed greatly over the years. In the First World War, the M1917 / M1917A1 helmets used by US troops were known as "Dabway" or "Dispun", which protected the soldiers' head. During the Second World War in 1941, the helmet was replaced by the M-1 "steel pot" helmet. In the 1980s US Helicopter Helmet was further improved by the Kevlar 29 missile fiber. The helmet used in the future may have more protection and convenience.
