| abstract | - UNSC body armour can be likened to scaled down, weight efeective tank armour consisting of composite metal and ceramic materials with energy abosrbing layers. Most armour has Titanium alluminide on the surface, acting as a structural support, giving limited ballistic resistant properties and acting as an ablative defence against energy weapons, effective lessening the effects of energy weapons at a cost of its self. Underneath that is a layer of boron carbide resin bonded to a layer of graphite composite carbon fibre. Boron Carbide is an incredibly tough ceramic material that acts as a pack up to the titanium alluminide as an ablative defence against energy weapons and as a projectile defence, shattering solid projectiles on contact and deforming to form a conoid base to absorb the impact. The Boron Carbide is so effective, it can even warp Brute Spiker rounds, perhaps even shattering them. Under this, a layer of carbon fibre absorbs the impact by absorbing the energy across a small area, protecting the user. At this point, the difference between armour becomes apparent. Many, cheaper and more mass-produced armour use a layer of Kevlar diamond weave which provides a last ditch protection and padding for the user. This will stop any rounds already slowed by the upper layers, catch any spalling or fragmentation from the other layers and act as a last ditch energy/heat resistant layer. More expensive armour types utilise a layer of nanocrystal gel, which provides three times the protection of its Kevlar counterparts, at almost five times the cost, leaving it for more expensive armour The MJOLNIR Powered Assault Armour Mark 7 however, is slightly different in design. As well as using thicker ceramic, carbon fibre and nanocrystal layers, it uses a strong titanium alloy. Heavier than Titanium Alluminide but many times stronger, it lends to the MJOLNIRs infamous power.
