Marine armor (Far Harbor)

Marine armor is a set of armor in the Fallout 4 add-on Far Harbor.

Background
An advanced model of combat armor utilized by US Marines stationed at the Mount Desert Island Naval Facility before the Great War. Several suits of the armor, in various states of deterioration, were already inside the base when the bombs dropped and were adopted by high-ranking members of the Church of the Children of Atom. More shipments of the armor were on their way to the base when the bombs fell.

Characteristics
Marine armor is a top-tier armor, and its protective qualities are stated to be surpassed only by power armor. Its Damage Resistance and Energy Resistance are far superior to what a full set of upgraded heavy combat armor can provide, topped off with a decent amount of Radiation Resistance, to boot.

The downside is the armor's extremely high weight - at 95 pounds for the full set, it weighs more than T-60 power armor without a frame to bear the load.

Aesthetically, Marine armor appears like a cross between an early-stage power armor prototype and an Explosive Ordnance Disposal (EOD) suit, with thick reinforced plating covering every part of the body. The torso piece incorporates a power pack mounted to its back as well as a thick pipe on the chest that might hint at some sort of air filtration or cooling system. Both are purely cosmetic and do not add any functionality to the armor in-game. The same is true for the armor's multiple pockets.

Parts and armor mods
Contrary to all other armor sets, Marine armor versions are craftable modifications instead of fixed tiers and therefore quite similar to power armor upgrades. A set of Zealot armor can be upgraded to Assault armor or Inquisitor armor at any armor workbench, provided that the player meets the required Armorer and Science! perk levels. Regardless of perk level, both the Assault helmet and the Tactical helmet cannot be modified in any way.

Variants

 * Atom's Bulwark (Damage resistance and energy resistance increase with rads): The High Confessor gives this armor piece to the Sole Survivor after completing Reformation or Cleansing the Land. It can spawn as a chest piece or any limb piece.
 * Marine wetsuit & tactical helmet

Recon Marine Armor
The specialized "Recon" Marine armor items are an almost complete set of legendary Marine armor versions, minus the legs. They can be purchased from various vendors around the island. Armor workbench upgrades can be applied as usual.
 * Recon Marine helmet (+1 Agility and Perception): Purchased from Brooks in Far Harbor.
 * Recon Marine chest piece (Reduces damage while standing and not moving by 15%): Purchased from Cog in Acadia.
 * Recon Marine right arm (Increases wearer’s movement speed by 10%): Purchased from Sister Mai in the Children of Atom base, The Nucleus.
 * Recon Marine left arm (Temporarily slows time during combat when the Sole Survivor's hit points are at 20% or less): Purchased from Kane in the Children of Atom base, the Nucleus.

Locations

 * A complete set of Marine armor can be found scattered across three steamer trunks located in wrecked ships off the coast of Far Harbor. However, it can only be acquired after unlocking the fifth and last of DiMA's memories during the quest Best Left Forgotten. Doing so will start a miscellaneous quest to recover the armor pieces. The steamer trunks will only appear upon acquisition of this quest, thus making it impossible to claim the armor beforehand. All armor pieces are found in their Assault armor configuration (if applicable) and may spawn with random leveled modifications.
 * Both legs can be found due west of Haddock Cove in the easternmost section of the sunken ship.
 * The chest, helmet, tactical helmet, and the Marine wetsuit are located south by southwest of Rayburn Point in a sunken shipping container.
 * Both arms can be found due east of the Harbor Grand Hotel on the stern of a sunken ship.
 * The full Zealot Marine armor set (minus the helmet) is available for purchase from Kane, the Children of Atom's armor vendor in the Nucleus, every time his store is replenished.
 * Several of the Children of Atom Zealots in and around the Nucleus including Grand Zealot Richter wear incomplete sets with the Zealot modification. None of these sets includes a helmet.
 * The two zealots who guard the front entrance outside of the bunker can be stealth-killed without turning the rest of the Children of Atom hostile to the Sole Survivor. Note that these guards disappear from the Island along with the rest of the Children of Atom if the Nucleus is destroyed during the Far Harbor main questline.
