Power armour is fully sealed, isolating the wearer from the outside environment and protecting him from gas weapons and harsh atmospheres. Should a penetration occur, resulting in a leak of the environmental seal, a quick application of [[repair cement]] is sufficient to restore its sealed environment (at least temporarily), though more advanced patterns such as [[artificer armour]] may have automated fibre re-weaving or similar systems. {{Fn|60}} It also commonly includes numerous auxiliary systems such as communicators and auto-senses. The backpack contains the main power plant, environmental system and additional stabilizers.{{Fn|1}} The primary power source is a fusion generator which is capable of lasting forever with the proper care.{{Fn|60}} This is important, as should a Space Marine's power armors armours motive system completely fail due to critical damage, the armour is very heavy and becomes a hindrance slowing the marine down making it difficult so much as to move around in unpowered armour.{{Fn|60}} The backpack also houses a small [[Stacked Atomic Chain]] battery, powering the suit's life-support, air recycling, fluid recovery and various automated medical functions.{{Fn|65}} Still, should a marine require it, power packs also contain spare energy cells and a solar converter to recharge them.{{Fn|61}} All armour may further be augmented by various artefacts, relics and enhancements such as [[pauldrons]] and [[greaves]].{{Fn|1}} The most important part of the armour scheme of Power Armour are its [[ceramite]] armour plates. These are individually up to an inch thick and are honeycombed to help dissipate energy and localise damage suffered.{{Fn|65}} Thanks to its ceramite and [[adamantium]] exterior, Power Armour is almost invisible to heat detection.{{Fn|64}}

[[Company Champion]]s wear armours specifically crafted for them. This pattern of armor armour is known informally as the '''Curadh''' variant and is based loosely on '''Aquila'''-pattern battleplate. It features additional reinforcement upon the shoulder guards, designed to showcase the Champion's many honours and provide better protection. It also comes with a reinforced breastplate emblazoned with a winged shield, where a Champion is allowed to display his personal heraldry. As for the helm it is deliberately fashioned to resemble knightly helms of [[Terra|Terra's]] ancient past.{{Fn|32}} This armour pattern was also available to Sergeant [[Revok]] of the [[Fire Angels]] Chapter.{{Fn|33}}

Like [[power armour]], Terminator suits have an outer shell of [[ceramite]]-bonded plates powered by electrically-motivated fibre bundles. Plates of heavy [[plasteel]] further armour the ceramite sections, especially on the front of the suit. This extra armouring provides a level of protection that is far superior to normal Marine armorarmour; not even a [[Missile_launcher#Imperial_Munitions_Types|Krak missile]] will penetrate the suit's breastplate.{{Fn|23}}
