Changes

Power armour has been in use since before the [[Age of the Imperium]], from the techno-barbarians of [[Earth]] to the original Space Marines created by the [[Emperor]]. Over the history of the [[Imperium]], power armour has developed into many different forms. Need, circumstances and recovery of new materials and technology has shaped the armour's evolution.{{Fn|1}}{{Fn|65}}

Space Marine Power Armour is an extraordinarily sophisticated defensive system which combines huge resistance to physical damage with a sensory array and sealed environment which protects its wearer from the ravages of the void and alien atmospheres. Integrated with the armour are networks of electro-motivated fibre bundles which mimic and augment the muscular strength of the wearer, so long as it remains powered.{{Fn|2b}}{{Fn|60b}} The true genius of the design, however, lies in its close integration with the already superhuman physiology, senses and reflexes of the Space Marine within. Working in concert, armour and Astartes together become a weapon without equal.{{Fn|2b}} Space Marine Power Armour can withstand [[Lasgun|las-fire]], [[Bolter|bolt rounds]], even [[Autocannon|cannon shots]], but is significantly weaker at resisting [[power sword]]s, which can cut through it with ease.{{Fn|59}} Power Amour reduces the damage taken from small arms somewhere between 50 to 85 percent, even offering at least some protection against all but the most devastating weapons deployed on the battlefield.{{Fn|65}}
