Marine Combat Armor beats every other non-power armor in the game with a full-set total of 159 Damage Resistance and 158 Energy Resistance [3]. Heavy Combat Armor, which most players can craft by level 20, sits at 111/111 [7]. That 48-point gap sounds decisive until you check how Fallout 4 actually converts DR into damage reduction — and the answer is that it depends entirely on what’s shooting you.
This guide ranks every armor set by its verified DR and ER totals, explains the diminishing-returns formula that decides whether those numbers matter, and tells you exactly where to get the pieces worth building toward.
Quick Answer: The Full Tier List
Numbers below are full-set totals (five or six pieces) for the standard/base version of each set, pulled directly from Fallout Wiki’s item tables [3][4][5][7][8][9][10][11]. Power armor DR includes physical resistance only — see the power armor section for energy and radiation figures.
| Armor Set | DR | ER | Best For | Avoid If |
|---|---|---|---|---|
| Raider (standard) | 10 | 8 | Levels 1–5 only | You’ve left Sanctuary Hills |
| Leather (standard) | 9 | 26 | Early energy-weapon fights | Raiders with pipe guns are the threat |
| Metal (standard) | 40 | 17 | Early ballistic fights | You’re fighting synths or Institute troops |
| Combat, standard | 59 | 59 | Mixed early-mid game | You have Armorer 3+ already |
| Combat, sturdy | 85 | 85 | Mid-game all-rounder | You’re heading into Far Harbor soon |
| Combat, heavy | 111 | 111 | Late-game non-power build | Weight is your bottleneck (49.5 total) |
| Heavy Synth | 103 | 120 | Energy-weapon-heavy fights (Institute, synths) | You mostly fight raiders/ballistic damage |
| Marine, Assault | 159 | 158 | Best non-power option, period | You haven’t reached Far Harbor |
| T-60 power armor | 900 | 645 | Early power armor access, fusion cores permitting | You’re not ready to manage fusion core supply |
| X-01 power armor | 1220–1820 | 790–1390 | Endgame tank builds | You want mobility over raw survivability |
How Armor Resistance Actually Works
Fallout 4 splits your outfit into 9 slots across 2 layers: a base layer (body, hat, eyewear, mouth, and hands) worn underneath, and an armor layer (chest, both arms, both legs) worn on top [1]. Each layer stacks its own DR and ER, which is why a modded outfit plus separate limb armor can out-resist a single full suit. Stepping into power armor overrides all of it — every bonus from your underlying clothes and armor gets nullified the moment you climb in [1].
Here’s the part almost no ranking explains: DR in Fallout 4 isn’t a flat percentage. It’s a ratio between your resistance and the attack’s raw damage, and it has heavy diminishing returns [2]. If your DR exactly equals the incoming hit’s damage, you take half. A 50 DR chest piece against a 50-damage shot cuts it to 25 damage. Push DR to double the incoming damage and you’re not at 100% reduction — you’re deep into a curve that flattens fast. That’s why a legendary enemy’s 200-damage critical still hurts through a 900 DR suit of power armor, and why Heavy Combat Armor’s 111 DR closes most of the practical gap against Marine armor’s 159 DR when you’re only taking 20–40 damage per raider round. The resistance gap matters far more against heavy hitters (deathclaws, Gunner snipers, suicider blasts) than against basic small arms.
Raider, Leather & Metal: Don’t Wear These Past Level 15
Raider armor caps out at a genuinely poor 10 DR / 8 ER for the full five-piece set — it’s scrap plating held together with tape, and the game treats it that way [9]. Leather trades toward energy resistance (9 DR / 26 ER), while Metal trades toward ballistic (40 DR / 17 ER) [10][11]. Neither is “better” in isolation; they’re built for different threats, which is the first real decision point in the game rather than a formality. Once Combat Armor starts dropping around level 15–20, all three starting tiers stop being worth the crafting materials.
Combat Armor: The Set You’ll Actually Live In
Combat Armor is the mid-game backbone because it’s the only common set that splits DR and ER evenly instead of favoring one damage type [7]. Standard combat totals 59/59, Sturdy jumps to 85/85, and Heavy tops out at 111/111 for 49.5 lbs of weight and 905 caps of value [7]. It requires Armorer ranks 2 through 4 to craft the three tiers, and because every piece can take the same mods as the others, it’s the set to build a legendary collection around — you’ll likely be swapping individual legendary pieces in and out of a Combat Armor base for most of a playthrough.
Heavy Synth Armor: The Energy-Weapon Specialist
Heavy Synth Armor totals 103 DR / 120 ER, which makes it the strongest energy-resistant option outside Marine armor and power armor [8]. It drops off Gen 1 and Gen 2 synths around Mahkra Fishpacking, University Point, and inside the Institute itself [8]. If you’re heading into a fight stacked with laser or plasma weapons — Institute Coursers, synth patrols — this outperforms Heavy Combat Armor’s balanced split for that specific threat.
Marine Combat Armor: The Best Non-Power Armor in the Game
Assault Marine Armor’s 159 DR / 158 ER full-set total beats every other non-power option, and it’s not close [3]. Getting it isn’t a vendor purchase or a random drop — it’s tied to a Far Harbor questline most players finish without realizing what it unlocks. Completing DiMA’s fifth memory during “Best Left Forgotten” spawns three steamer trunks: legs west of Haddock Cove, chest and helmet near Rayburn Point, arms east of the Harbor Grand Hotel [3]. The pieces come in as the base Zealot’s configuration; upgrading to Assault (balanced) or Inquisitor’s (near-identical, energy-leaning) requires Armorer rank 4 and Science! rank 4 at any armor workbench [3]. Skip the memory quest and you never see the trunks spawn.
Ballistic Weave: Turn Any Outfit Into Armor
Ballistic weave adds up to 110 DR / 110 ER to a single piece of compatible clothing at max rank (Mk V), and because it’s applied to clothing rather than armor plating, it stacks in the base layer underneath separate limb armor [6]. You don’t get it from a perk or a shop — it unlocks through the Railroad faction. Run one or two Jackpot missions for P.A.M. after completing Boston After Dark and Mercer Safehouse, and Tinker Tom will teach you the mod at Railroad HQ [6]. Each higher rank also requires matching Armorer perk levels to install. Side with the Institute and wipe out the Railroad, or finish “Blind Betrayal,” and the mod becomes permanently unavailable — so unlock it before committing to either path if you want the option later [6].
Power Armor: When 900+ DR Actually Pays Off
T-60 power armor’s base Model A totals 900 physical DR, 645 energy resistance, and 1050 radiation resistance [5]. X-01, the strongest set in the base game, starts at 1220/790/1050 in its base Mk I form and climbs to 1820/1390 fully upgraded to Mk VI [4]. Both require a power armor frame and drain fusion cores while worn, and neither one’s bonuses apply if you’re not actually wearing the frame with cores loaded.
Given the diminishing-returns curve above, that four-figure DR isn’t overkill against everyday threats — it’s what turns a one-shot kill from a deathclaw swipe or a mininuke into something you walk away from. Against a raider with a pipe pistol, though, you’re paying fusion-core upkeep for protection Heavy Combat Armor already covers most of.
Which Armor Fits Your Playstyle
| Player Type | Priority |
|---|---|
| New player | Wear whatever drops until Combat Armor unlocks around level 15–20; don’t sink resources into Raider/Leather/Metal mods. |
| Casual player | Craft Heavy Combat Armor and stop there — 111/111 covers the entire main story without a fusion core supply chain to manage. |
| Hardcore/optimiser | Rush Far Harbor for Marine armor, then layer ballistic weave into your underarmor slot for stacked resistance beyond the 159/158 cap. |
| Completionist | Collect and mod every set for the crafting/legendary variety, but keep Marine or X-01 as your actual combat loadout rather than whatever you’re displaying. |
The Starter Kit Worth Building Toward
If you’re optimizing rather than collecting, four things compound well together: Heavy Combat Armor as your base (111/111, craftable early with Armorer 4), a ballistic-weave-modded underarmor piece for the stacked base-layer bonus, the Ballistic weave unlock itself from the Railroad questline before you commit to another faction, and a power armor frame parked at a settlement for emergency use against high-damage encounters. None of these lock you out of switching to Marine armor later once Far Harbor is accessible.
When NOT to Bother With Power Armor
Skip power armor as your main loadout if you’re not managing a fusion core stockpile, since an empty core strands you mid-fight with none of the suit’s bonuses active. It also fights your Sneak perk investment — the suit’s bulk and footstep noise work against stealth even though it doesn’t fully disable it — so a stealth-focused build built around Agility perks generally loses more than it gains from the DR jump.
FAQ
Is Marine armor better than power armor?
No, not by raw numbers — even base T-60 nearly quintuples Marine armor’s DR. Marine armor wins on flexibility: no fusion cores, full compatibility with sneaking and Agility perks, and it stacks with ballistic weave underneath, which power armor can’t use at all.
Should I upgrade Combat Armor or switch to Marine armor once I reach Far Harbor?
Switch, if you’re optimizing for pure resistance — 159/158 beats Heavy Combat’s 111/111 outright. But if you’ve already sunk legendary mods into a Combat Armor set, the fusion-core-free flexibility argument for sticking with it is real; the practical damage-reduction gap against most enemies is smaller than the raw number gap thanks to the diminishing-returns curve above.
Is Heavy Synth Armor worth farming over Combat Armor?
Only if you’re heading into energy-weapon-heavy fights specifically. Its 120 ER beats Heavy Combat’s 111, but its 103 DR is lower, so it’s a situational swap, not a straight upgrade.
