Combat skin

Combat Skin is a Forerunner term used to talk about body armor. In has a classification system from Class 1 to at least Class 12. There may be more higher classes after 12. According to 343 Guilty Spark the MJOLNIR armour is ranked on this scale as Class 2.

Armor of the Forerunner
Not much is known about Combat Skin. It first comes up in Halo in the level Library when 343 Guilty Spark wonders why the Master Chief had brought "such ineffective weapons" to combat the Flood, and recommends that the Chief upgrades from the MJOLNIR armour, which, according to some Forerunner ranking system, the criteria of which is not gone into, is only Class 2. 343 Guilty Spark suggests Master Chief that he upgrade to a Class 12 Combat Skin, which 343 says is necessary to combat the Flood.

What does the Class System mean
Due to the fact that not much information is know about Combat skin there is some debate on what exactly the Combat Skin refers to. The confusion is made worse by various quotes from the halo Universe:

As shown above 343 says that Master Chief upgrade his armor thus referring to Combat Skin as a type of armour where the MJOLNIR armour is Class 2. However, later 343 talks about the Flood changing the atmosphere, he says "Your Environment Suit should serve you well..." implying that the MJOLNIR armour in Forerunner terms is an Environment Suit. The differing nomenclature has led some to believe that the two items 343 refers to are different, i.e. your armour is what he refers to as the 'Environment Suit', and your 'Combat Skin' is the Chief's flesh and body. However this to is contradicted when in Halo: The Flood, the Master Chief upon hearing this he should upgrade from Class 2 to 12 he, thinks, "If there's a battle suit six times more powerful than the MJOLNIR armor, I'll be first in line to try it on," implying that the Combat Skin classes are indeed ranked according to strength.
