Although the US military requirements for body armor mirror the NIJ's on a surface level, the two are very different systems. The two systems share a 44 mm (1.7 in) limit on back-face deformation, but SAPI-series plates increase linearly in protection (with each plate tested against the preceding plate's threats), and require a soft armor ...
Ceramic tiles have a multiple hit capability problem in that they cannot sustain successive impacts without quickly losing much of their protective value. [6] To minimise the effects of this the tiles are made as small as possible, but the matrix elements have a minimal practical thickness of about 25 mm (approximately one inch), and the ratio of coverage provided by tiles would become ...
Armour is generally encouraged to look like its historical counterpart, [4] though differences are often necessary to comply with safety requirements, and sometimes modern sport armour may be used [8] One of the most common examples is the face of a helmet: While many types of historical helm had no face protection, safety rules require full ...
The Improved Outer Tactical Vest (IOTV) is an enhanced version of, and a replacement for, the older Outer Tactical Vest (OTV) component of the Interceptor multi-threat body armor system, as fielded by the United States Army beginning in the mid-2000s.
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.
The first usage of the term "flak jacket" refers to the armor originally developed by the Wilkinson Sword company during World War II to help protect Royal Air Force (RAF) aircrew from the flying debris and shell fragments thrown by German anti-aircraft guns' high-explosive shells (flak itself is an abbreviation for the German word ...

A man wearing Samurai armor and jinbaori (sleeveless jacket) turns around, 2019. Scholars agree that Japanese armour first appeared in the 4th century, with the discovery of the cuirass and basic helmets in graves. [1] During the Heian period (794–1185), the unique Japanese samurai armour ō-yoroi and dō-maru appeared. [2]
