The shield, called a "telamon", was made of bronze plated wood and was worn hung around the neck so as to free up both hands to wield the sarissa. [5] All of the armor and weaponry a phalangite would carry totaled about 40 pounds, which was close to 10 pounds less than the weight of Greek hoplites' equipment.

A Chinese publication lists 30MnCrNiMo "685" steel as the material used in Chinese rolled armor plates, with a Brinell Hardness of HBW 444-514 (thin) / 429-495 (thick). According to the same publication, older vehicles use a 22SiMn2TiB "616" steel with a hardness of HBS ≤ 219.
Within the Ministry of Defence (MoD), Chobham usually refers specifically to the non-explosive reactive armor & ceramic composites, while Dorchester is usually in reference to additional armour packages, primarily composed of explosive reactive armour and spaced armour, although these are often conflated when in colloquial usage.
The first prototype of the shield was believed to be created in the Late Neolithic Age. However the oldest surviving shields date to sometime in the Bronze Age. [3] The oldest form of shield was a protection device designed to block attacks by hand weapons, such as swords, axes and maces, or ranged weapons like sling-stones and arrows.
The Whipple shield uses the principle of spaced armour to protect spacecraft from the impacts of very fast micrometeoroids. The impact with the first wall melts or breaks up the incoming particle, causing fragments to be spread over a wider area when striking the subsequent walls.
