The oldest known use of helmets was by Assyrian soldiers in 900BC, who wore thick leather or bronze helmets to protect the head from blunt object and sword blows and arrow strikes in combat.
An arrow is a fin-stabilized projectile that is launched via a bow, and usually consists of a long straight stiff shaft with stabilizers called fletchings, as well as a weighty arrowhead attached to the front end, and a slot at the rear end called the nock for engaging the bowstring.
Bronze is an alloy consisting primarily of copper, commonly with about 12% tin and often with the addition of other metals and sometimes non-metals or metalloids such as arsenic, phosphorus or silicon.
A sword is a bladed, melee weapon intended for slashing or thrusting that is longer than a knife or dagger, consisting of a long blade attached to a hilt.

Since the 1990s, most helmets are made from resin or plastic, which may be reinforced with fibers such as aramids.
In polymer chemistry and materials science, resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers.
The word helmet is diminutive from helm, a medieval word for protective combat headgear.
A diminutive is a word which has been modified to convey a slighter degree of its root meaning, to convey the smallness of the object or quality named, or to convey a sense of intimacy or endearment.
The Medieval great helm covers the whole head and often is accompanied with camail protecting throat and neck as well.
