Light combat armor consisting of layers of synthetic chitin and diamondoid plating over an underlayer of kevlar and arachnoweave. First employed in approximately 45 a.t. by American, Australian, and European military and security personnel working in peacekeeping or riot control situations. Although slightly cumbersome, the armor was effective against the newly developed carboweave knives and Deep Penetrator classes of ammunition made possible by the developing bio- ceramic technologies.
Later advances in bionano production and quality control technologies increased the damage resistance of the armor while reducing its thickness and weight. These advances in turn led to carapace armor being retained in the arsenals of planetary and habitat security forces into the early Interplanetary Age as well as enjoying a relatively brief stint in the military forces of the time until the development of synsects and other swarm-based and ai controlled weapons systems made humans in combat essentially superfluous.
In the modern era, original suits of carapace armor can be found in the Museum of Human History on Luna as well as the collections of several museums and ancient weapons enthusiasts scattered across the Inner Sphere. In addition, some ludd and prim cultures, as well as era-appropriate societums have been observed to employ the armor in combat situations. Finally, nanotech copies of the armor can be seen in the occasional historical reenactment or mock combat scenario of the pleasure habitats of the NoCoZo and Utopia Sphere.
Ablative Armour - Text by M. Alan Kazlev Any armour that protects against beam or HE weapons by ablating, or vapourizing, as it is hit, dissipating the destructive effect of the weapon. Because ablative armour is soon eroded it is not much use in a sustained firefight. Includes soft, hard, laminated, reactive, and smart ablatives.
Arachnoweave - Text by M. Alan Kazlev Fabric created using biomimemetic synthesis of spider-silk proteins. Strong yet subtle and light, used for a variety of purposes, including police and military body armor, sporting clothing, and fashion statements.
Armour - Text by M. Alan Kazlev  A defensive covering, as of adamant, arachnoweave, kevlar, metal, wood, or leather, worn to protect the body against weapons (see also Body Armour).  A tough, protective covering, such as the chitinous exoskeleton or carapace or bony scales covering certain animals, dermoplasts and armoplasts of certain neogens, or the metallic plates on tanks or warships or shielding or laminated passive or active armour of a fighter or a starship.  The combat arm that deploys armoured vehicles, such as tanks or Mecha, or the individual units and armoured vehicles.  A blue or khaki goo shield.
