There are '''eightseven''' types tiers of Armor Class: '''C1, C2, C3, A1, A2, A3, A4, A5'''. There is also a ninth type They are usually grouped in two categories depending on their prefix: '''RawCx''' and '''Ax'''. Certain types of armor have '''Variable AC''', which has a special status; see this concept is explained in its own section below for more information.

The first three two Armor Classes, referred to as '''unarmored''' and shortened to '''Cx''', are referred to as such because they offer a level of protection expected of '''clothing'''; light, non-armored clothes.

* Little to no reduction of [[Pain]] damage.** '''C1''': As the lowest value, it is the value used to refer to '''base (Pain) damage'''. It represents the protection level of naked human skin or comparable light animal hides.** '''C2''': Pain received is typically reduced by '''0represents the protection level of heavy clothing or heavier, tougher animal hides, such as a leather jacket.95x to 0.97x''' (3% to 5% less damage) compared to C1 (actual values may vary depending on individual weapons)** '''C3''': Pain received is typically reduced by '''0.90x to 0.95x''' (5% to 10% less damage) compared to C1 (as before, actual values may vary)* No reduction of [[Limb damage]]at all.* [[Ammunition|Expanding ammunition]] is more effective, but armor-piercing ammunition is less effective.

* Reduction of [[Pain]] damage , roughly proportional to level number.** '''A1''': Represents a protection rating equivalent to that of super-light , or obsolete body armor , such as an armored tuxedo or very tough hidesa flak jacket. Pain received is typically reduced by '''0.7x to 0.8x''' (20% to 30% less damage) compared to C1 (as before, actual values may vary)** '''A2''': Represents a protection rating equivalent to that of light body armor, such as a Light T armor vest. Pain received is typically reduced by '''0.55x to 0.65x''' (35% to 45% less damage) compared to C1 (as before, actual values may vary)** '''A3''': Represents a protection rating equivalent to that of medium body armor, such as a Heavy K armor vest. Pain received is typically reduced by '''0.4x to 0.5x''' (50% to 60% less damage) compared to C1 (as before, actual values may vary)** '''A4''': Represents a protection rating equivalent to that of heavy body armor, such as an EOD suit. Pain received is typically reduced by '''0.2x to 0.25x''' (75% to 80% less damage) compared to C1 (as before, actual values may vary)** '''A5''': Represents a protection rating equivalent to that of super-heavy or advanced body armor or advanced technology. Pain received is typically reduced by '''0.033x to 0.075x''' (92.50% to ~96.66% less damage) compared to C1 (as before, actual values may vary)

* [[Ammunition|Armor-piercing ammunition]] is more effective, but expanding ammunition is less effective.

== Raw Armor Class Variable AC ==

The last Certain items in the game; namely types of powered armor, have an AC, rating listed as '''RawVariable'''. This means that depending on the charge level of their battery, is special; it is not found as a part the level of damage tables and is not protection provided by any piece of wearable clothing or armor, and is instead exclusively found as an attribute of certain creatures and even certain inanimate objects (locks on containers, pieces of cover...)will change.

"Raw" represents an "absence" of Armor Class, in the sense that creatures and objects with Raw Variable AC must instead be destroyed by reducing their lose '''0.1 battery power''' every time it receives as hit dealing at least '''1 [[Limb limb damage|hit points]] to zero'''. The armor's current AC level depends on the current amount of battery power.

Creatures and objects with raw AC cannot feel [[Pain]] and are thus immune In order to Pain damagerefill battery power, however they usually also have what is called an '''AC equivalentHITB batteries''', which is must be used to determine Limb Damage reduction; each restores '''1.0 power''', and except on the effectiveness of certain '''[[Ammunition|types List of ammunitionhuman clothing and armor#Body armor|Powered Combat Vest]]''', which only regains '''0.5 power''' per battery. Variable AC manifests in two ways; as a set AC for human clothing, and as an AC tier modifier for youkai outfits. Youkai outfits have different AC tier modifiers. {| class="wikitable sortable" style="font-size:10pt;text-align:center"|-! Battery power !! Armor Class<br/>(Human clothing) !!
