Wastelander armor is almost all sourced from the Brotherhood of the Land of NOD through their connections with the Eden Initiative.
Wastelander Armor is most commonly cobbled together out of what materials were available at the time, and while some individual pieces might be of more conventional standard light armor composites stolen from broken or destroyed suits, or commercial armor grade ferroplastics, more often than not the components are typically metal plate with canvas, leather, or woven plastic backing.
The upside to primitive armors is that in the wastelands, they are easy to repair. Materials are also readily available, even if they aren't ideal. The heavy weight of the armor also means that only the largest and strongest specimens are able to wear it and use it effectively. These individuals tend to be just as dangerous out of their armor as in it, a trait not always shared by armored infantry of the first world nations. There are other low tech advantages that are not immediately obvious. Primitive armors do not require power sources, and do not generate an EM signature. There are entire fields of weapons and guided munitions designed to home in on the EM signature of power armor suits and armor suits in general.
Chemical Augmentation System - Standard Issue
Given the size and weight of most primitive armor, it would be very tiring and restrictive for even athletic wastelanders to wear. To counter this issue, all but the most primitive and cheaply made suits have a degree of a chemical augmentation system, if for nothing more than muscle augmentation to move the suit in times of conflict.
Some Wastelander Armor can become quite sophisticated (relatively speaking), and have mid to upper tier chemical augmentation systems installed under the armor. Between quickly administered painkillers, combat drugs and stimulants, and other military grade compounds, soldiers and would be terrorists can keep walking and fighting even after sustaining mortal injuries.
Lack of Gadgets - a standard issue set of SLAB armor used for secondary infantry forces in most first world militaries are equipped with SmartGun targeting systems, enhanced optics, communications systems, CogNet and LAN uplink capabilities, and some high end armors have optical camouflage capabilities. These armors are expensive compared to Wastelander armor, and take a good deal of training to use effectively. Most Wastelander armor training can be done in a day, it is very simple stuff.
Substandard Wastelander Armor
Substandard Armor has an improvised helmet, often zero modifications, and less than half have any sort of chemical augmentation system, and of those, only about 10% are of basic quality. Substandard armors are usually repaired or bashed together from damaged armors, or sold on the cheap by armor dealers looking to clear out their junkpiles. These armors are also commonly found among Wasteland merchants, raiders, and lack the animal/mythological motifs of the Edenian sourced armors.
These armors are mostly used in the fighting and skirmishes between denizens of the wastelands, and these individuals typically only have access to antique and improvised weapons, and even if they were to pick up something as powerful or dangerous as a modern military weapon, the majority would be unable to keep it operational long. Given that the typical wastelander is armed with primitive guns and rifles, and the monsters they typically face do not have energy weapons, magnetic weapons, or such, they are not armored to deal with such. These armors are more effective against claws, knives, protecting vitals, and stopping low calibre and low velocity guns.
Badlander - Badlander Armor is the Cosmic Era equivalent to heavy cloth and animal hide armors from medieval and fantasy settings, but the materials are modern synthetics mixed with both mundane animal hide, and the hides/carapaces of creatures that have wandered into reality through dimensional fatigue events. It is very common for Badlander armor to mix in pieces of other armor suits, or even just random pieces of metal and other materials that look like they could stop a blade or a primitive pistol. Badlander armors made of alien hides can be frightening to look at, as well as carry strange parasites and function as vectors for strange diseases.
Blastmaster - The Blastmaster armor is made out of conventional armor and gear worn by police and firefighters. Given the long and violent history of the areas deemed wastelands, especially in the ruins of the Middle East, this gear is easy to come by. The armor is supplemented in the typical addition of metal and other resilient objects to improve the durability of the armor. Most Blastmaster armors have a gas mask, or breather allowing them to operate in heavy smoke, or noxious air conditions with relative ease.
Painspike - Painspike armor is made from scavenged materials that are either decorated with sharp things, or have sharp things such as heavy nails and shrapnel driven through it from the backside. While often inconvenient to wear, Painspike can be intimidating, and in close quarters combat, effective.
Sadist - Sadist armors are typically half Painspike and half Badlander with a gladiatorial design to them. The people who wear these armors demonstrate the fact that not only are they warriors of the wastelands, they make a special place in their skillset for killing people.
Linebacker/Gridiron - This armor type was common to North America and was made from repurposing sports and athletic protective equipment into combat armor, typically by covering the plastic components with metal, kevlar, and other strongly resistant materials.
Iconoclast - Made from ABC (atomic/biological/chemical) suits, these armors have a thick and padded appearance, but are quite tough, but are heavy, and hot to wear for prolonged periods of time.
Basic Issue Wastelander/Generic Armor
The standard issue 'wastelander' armor has a helmet, a chemical filtration system, rebreather, and some of the other other accoutrements of standard light body armor. Like the other armors listed, the basic issue wastelander armor is made of readily available materials, rather than military grade armor produced in massive factories. Metal alloys, bullet and claw resistant polymers, and some ceramics create an often bulky armor that is for the most part effective in the harsh environment of the Wastelands.
Coalition Suit - A dated combat suit, the Coalition suit was designed over two centuries ago, and there is a single factory still making most of the parts to field this armor. It is made of a large number of ferroceramic plates with hardened steel jacketing and a kevlar underpinning. The Coalition Suit remains popular as it is well suited for facing things with claws and fangs, and the ceramic plating is a good deal more resistant to things like acidic saliva or other corrosive fluids often found leaking from dimensional anomalies.
Elite Armor Suits
The Brotherhood of the Land of Nod and it's Eden Initiative backers supplement the armor available to the Brotherhood with elite wastelander armors. There armors have a few gadgets, all have chemical augmentation systems, and they are all designed with a thematic element. This draws on the connection that both the Noddites and the Edenians place between religion and technology.
The Horus armor is uncommon, and generally reserved for special forces, commandos, and high ranking officers inside of the Brotherhood, and mercenary and tribal factions aligned with the Brotherhood. The Horus suit is among the most sophisticated, have both enhanced optics (long range vision, motion sensor) as well as a top end chemical augmentation system.
Designed for stealth operations and night fighting, the Anubis is built for working in the dark and in silence. The armor is relatively light, but the helmet has either an archaic forward looking IR system or a digital low light optical system.
The lion-headed Bast type armor was designed for close quarters combat and is a heavier armor, and it is configured for the wastelander wearing it to be fighting with either melee weapons, or with close quarter weapons like pistols and SMGs, rather than long guns or heavy weapons. Bast armors have chemical augmentation systems tailored for combat aggression and pain resistance.
The Set Armor features a cobra head with hood and functions much like the Anubis armor, designed for low profile operations. The principle use for the Set armor, which is thankfully rare, is for terrorist attacks, assassinations, and other high profile attacks and killings. This armor has found it's way through the Silk Road to Amerikka Command in North America, where it has been used to mixed effect on the ground, but great effect through terror tactics.
The Sebek armor is designed with either a snorkel or a rebreather, allowing the armor to be worn and used underwater. Otherwise, it is a very basic armor with a standard chemical augmentation system and no other gadgets. It is rare, since most of the wastelands lacks water more than a few feet deep.
Also known as Heavy Wastelander Armor, the minotaur/Bull headed armor is larger and heavier, and has a robust chemical augmentation system to support it.
