A series of innocuous, solid looking, curved, semi-square, inch-and-a-half-thick plates.  On the front of the plates is emblazoned the words in square white text "MEDIUM STRIKE FACE  HANDLE WITH CARE."  Despite being an inch-and-a-half thick, these plates are surprising light and don't seem to break (or even flex) with a punch or when being dropped.  In fact, the plates barely react at all when subjected to such stress.  The surface layer of the plates seems to be coated in a fine, plasticine cloth over a thin, absorbent gel layer.

Ceradyne XSAPI Plus armor plates were designed as a lightweight alternative to the SEALs 2572575 plates or Joint Special Operation Command's Ceradyne AA4 UP G3 plates.  Its ingenious design incorporates several sandwiched layers of Ceradyne's boron carbide formula, with an anti-thermal, anti-sheering, coterminous gel between the plate layers (making the plates "multi-strike surface" in nature) and allowing for multiple hits from multi-stage (or post-ignition penetrator) projectiles.  It can withstand 1 - 3 shots of 12.7x99 API, 9 to 12 shots of 6.8x51mm XM1186 AP rounds and 6 - 9 shots of 7.62x51mm M993 AP rounds before the protective value of the armor suffers due to cracking (or "spider-webbing" as it is termed).  The armor is considered completely impervious to anything but modern rifle caliber rounds, and offers adamantine-level protection at a fraction of the weight of similarly protective armors.

This armor consists of a fitted metal chest piece worn with supple leather. Although it leaves the legs and arms relatively unprotected, this armor provides good protection for the wearer's vital organs while leaving the wearer relatively unencumbered.

Notes: Immunity: Critical Hits, Resistance: Bludgeoning, Piercing, and Slashing from Nonmagical Attacks, Disadvantage: Stealth, This armor insert is a component for any modern armor system. This means that the armor is made to be worn inside a vest or plate carrier and will provide it's maximum protective benefits inside a vest or plate carrier. It can be worn on the outside, or without a vest, but then the armor is considered "improvised" and comes with severe penalties for not wearing it in the way it was intended. Provides a 50% resistance to any bludgeoning, piercing, and slashing damage dealt from nonmagical weapons. Also provides immunity to critical hits. Stealth disadvantage is nullified when worn inside a vest or plate carrier., Combat, Warding
