Armor in Tarkov: Classes, Plates, Materials, and Repair

The problem: armor that looks strong and still gets you killed

You extract once in five raids even though you keep buying the most expensive vest you can afford, and the death screen keeps showing thorax hits from ammo you assumed your gear would stop. That frustration almost always comes from misunderstanding what an armor class actually promises. This guide walks through how armor works in Escape from Tarkov: the class system, the plate system hiding underneath it, coverage zones, materials, durability math, and repair economics, so you can stop paying top price for protection you are not really getting.

The single most important mindset shift is this: Tarkov armor is not a damage-reduction stat like in most shooters. It is a stop-or-penetrate system that rolls a chance on every single bullet. Either the round is stopped and you take only a small amount of blunt damage, or it punches through and hits your flesh, reduced by somewhere between nothing and about 40 percent. Understanding when that roll favors you, and when it is already lost before the fight starts, is what separates players who buy armor wisely from players who donate it.

Everything in this article is checked against Patch 1.1.5.0, which went live on September 8, 2026 during Season 1, KORD BREACH. Battlestate Games adjusts armor balance, plate availability, and material behavior between patches, so read the specific values here as a September 2026 snapshot rather than permanent rules, and re-verify after any major update lands.

By the end you will know why the community phrase class 6 armor actually refers to the plate inside the vest, which materials survive repeated repairs and which are disposable, how to read durability before trusting a secondhand vest, and how to match your protection tier to the ammunition you will realistically face at your stage of the wipe.

At a glance: the armor answer on one screen

If you only remember one screen from this guide, make it this one.

Armor class comes from two layers added together: the soft armor sewn into the vest, which is usually only class 2 or 3, and the hard plates you slot into marked pockets, which carry the real class 4 to 6 protection. A plate only guards the zones printed on it, typically front, back, and sometimes sides. Everything outside those zones, and everything the soft layer cannot handle, is where you actually die.

Material choice decides how long the armor stays useful, not just how it performs on the first hit. UHMWPE and titan plates can be repaired again and again; ceramic plates are roughly done after two repairs. When in doubt, buy for effective durability and coverage first, and for the headline class number second.

How the bullet-versus-armor roll actually works

Every time a round hits armor, the game calculates a penetration chance from three inputs: the armor class, the armor's remaining durability percent, and the bullet's penetration value. That chance is rolled once per hit. Impact angle does not change the penetration roll on body armor at all; angled shots only matter for helmets, which have a separate ricochet mechanic covered in the helmets guide.

If the roll succeeds and the bullet penetrates, its damage is reduced by an amount between 0 and 40 percent, driven by the same three inputs. There is a strong correlation between penetration chance and damage reduction: rounds that barely manage to get through tend to lose around 20 percent of their damage, while rounds that massively outclass the armor, such as M995 hitting a PACA, lose nothing at all.

If the roll fails, the bullet stops and you take blunt damage instead: a small percentage of the round's base damage that depends on the armor's hidden blunt throughput stat, the ammo's penetration, and the armor's class and remaining durability. Blunt damage is genuinely low and almost never what kills you, and it shrinks further when a soft layer sits between the plate and your body.

Two more rules shape real fights. First, each armor layer a bullet passes through strips away some of its penetration and damage, which is why the soft-plus-plate stack behaves better than either layer alone. Second, every hit wears the armor down by at least 1 point of durability per bullet, buckshot pellets included, and penetrating hits actually remove slightly less durability, roughly 10 to 15 percent less, than stopped ones. Armor is a consumable resource, not a permanent shield.

Armor classes: GOST BR1 through BR6

Tarkov's in-game armor classes 1 through 6 map directly onto the Russian GOST standard's BR1 to BR6 grades, using the post-2017 revision of that standard. You do not need to memorize the real-world ballistics behind GOST; what matters is the practical reading: a higher class resists ammunition with a higher penetration value, full stop.

The community measures the matchup between a round and an armor class on a 0 to 6 effectiveness scale taken from the ballistics data. At level 0, labeled pointless, twenty or more hits still will not get through. At level 3, slightly effective, expect five to nine hits with a low starting chance. At level 5, very effective, one to three hits usually decide it and the penetration chance quickly climbs past 90 percent. At level 6, basically ignores, the opening penetration chance is already above 80 percent before the armor has taken any damage at all.

The class number is a promise with three conditions attached: the armor must be at high durability, the bullet must land on a zone the armor actually covers, and the plate doing the work must match the class you think you are wearing. Break any one of those conditions and the class label on the item card is marketing, not protection. The next sections take those three conditions apart.

Soft armor plus plates: why class 6 really means the plate

The current armor system is built from two cooperating layers. The vest itself carries soft armor, and on almost every vest in the game that soft layer is only class 2 or 3, enough for pistols and fragments but not for rifle fire. The serious protection, classes 4 through 6, comes from hard ballistic plates inserted into dedicated pockets.

This is why the community phrase class 6 armor is technically wrong and practically useful at the same time. No vest's soft armor reaches class 6. When someone says they run a class 6 Slick or a class 6 Zabralo, they mean the carrier has class 6 plates in its front and back pockets. The LBT-6094A Slick's built-in soft layer is class 3; everything above that is the plate talking.

Plates protect only the zones printed on them. A front plate covers the thorax from the front, a back plate covers the back, and side plates, which have low durability in the 15 to 25 range, cover only the ribs. A bullet that slips past the plate edge, into the stomach of a thorax-only carrier or under the arm, meets only the soft layer or bare flesh.

Because plates are separate items, you can mix and match them inside one carrier: a premium UHMWPE plate in front where you face enemies, a cheaper plate in back, and no side plates at all if you want the mobility. Learning to build a carrier out of plates instead of buying the vest as a fixed product is the single biggest armor economy skill in the game.

Coverage zones: the stomach problem and the armpit nobody can fix

Armor in Tarkov protects specific body areas, and every armor item's inspection window shows exactly which ones it covers. The protectable list is long: face, top of head, nape, ears, eyes, jaws, throat, back of neck, thorax, stomach, back, sides, shoulders, groin, and buttocks. Vests differ enormously in how much of that list they touch.

Pure plate carriers like the Slick protect essentially the front and back thorax where the plates sit, and nothing else. Full-coverage suits like the 6B43 Zabralo-Sh, the FORT Redut-T5, and the IOTV Gen4 extend over the stomach, sides, throat, neck, shoulders, and groin, at a real cost in weight and movement penalties. You are choosing between protecting more of your body and getting to the fight faster.

The stakes of coverage come from the health system. If your head or thorax hits zero, you die on the spot. A blacked-out stomach does not kill you directly, but it drains hydration and energy fast and then spreads incoming damage across your whole body at a multiplied rate, which is nearly as fatal in practice. A light carrier that guards the thorax but leaves the stomach open is gambling that every incoming burst lands high.

One more humbling detail: some areas, the armpit being the notorious example, cannot be protected by any armor in the game. Even the heaviest suit in Tarkov has geometric weak points. Armor shifts the odds of every engagement; it never removes the possibility of an unlucky angle, and playing as if it does is how geared players donate kits to patient shooters.

Durability and effective durability: read the percent, not the label

Armor protection scales with remaining durability percent, and the percent is calculated against the item's original maximum, not its current maximum. A repaired Korund-VM front plate showing 45 out of 45 is actually computed as 45 out of the original 60, meaning 75 percent durability and correspondingly reduced protection. Two vests with the same class label can be very different pieces of equipment.

How fast durability burns is governed by destructibility, a hidden stat that never appears in the in-game item card. To compare how much punishment two armors truly absorb, divide durability by destructibility to get effective durability. A ceramic plate with 60 durability and a destructibility of 0.6 has an effective durability of 100. A titan plate at 55 durability and 0.4125 destructibility reaches about 133, and will outlive the ceramic plate by a wide margin.

Durability damage per hit scales with the ammo's penetration value, the armor class, the ammo's armor-damage percentage, and the material's destructibility. High armor-damage rounds exist specifically to shred plates fast, which is why a vest that survived one raid intact can be a liability by the third. Inspect durability percent before every raid, and treat anything chewed down past the halfway mark as a downgrade to a lower class.

Materials and destructibility: the hidden stat that decides lifespan

Destructibility values below come from ballistics reference data; the stat is hidden in game.

Aramid, the fabric of soft armor, has the lowest destructibility at 0.1875, which is part of why soft layers endure. Among plate materials, UHMWPE at 0.3375 is the repairability champion: light, durable per point, and able to survive many repair cycles while keeping good protection. Combined materials and titan sit in the middle, aluminium and armor steel degrade faster, and ceramic at 0.6 sheds durability quickest of all the plate materials. Glass shares the 0.6 value, which matters mostly for visors.

The material split creates two competing philosophies. Ceramic plates like the SPRTN Elaphros and Granit Br5 are light for their class and excellent for one or two hard raids, but they are nearly broken after about two repairs and should be treated as semi-disposable. UHMWPE plates like the PRTCTR Lightweight and the GAC 4sss2 are the long-term investment: heavier per class in some cases, but they come back from the repair bench ready to fight again many times.

When two plates share a class, compare material and effective durability before price. A class 5 ceramic plate and a class 5 UHMWPE plate stop the same first bullet, but across a week of raiding the UHMWPE plate is often the cheaper option per raid because it survives the repair loop. That calculation flips if you expect to die and lose the carrier anyway; then the cheapest plate that stops the threat wins.

Repair: traders, kits, skills, and the ceramic trap

You have two repair routes. Several traders list repairs among their services, including Prapor, Skier, and Mechanic, and you pay them cash to restore durability between raids. Alternatively, body armor repair kits are items you can find in raid and use from your stash, but only while you are outside a raid. Ballistic plates can also be repaired as separate items, which pairs naturally with the plate-swapping approach described earlier.

Every repair removes a slice of the item's maximum durability, which is why repaired armor never quite returns to new. How much you lose depends on your skills: the Light Armor and Heavy Armor skills reduce the max-durability penalty when repairing the corresponding armor types, while the Intelligence skill affects how many repair points a kit spends. The exact cost and quality difference between trader repair and kit repair is not fully documented in current research, so treat detailed comparisons you see elsewhere as unverified as of Patch 1.1.5.0.

Repairs also carry a small upside: armor repaired with kits can receive a common or rare enhancement, a temporary bonus that works within a certain durability range and disappears on the next repair. Do not build a strategy around rolling enhancements, but enjoy them when they show up.

The ceramic trap deserves its own warning. Because repairability tracks material, a ceramic plate is close to scrap after roughly two trips to the repair bench, while UHMWPE plates like the PRTCTR and GAC 4sss2 survive many cycles. If you loot a high-class ceramic plate at low durability, its resale value is mostly fiction; if you loot a high-class UHMWPE plate in the same state, it may still be worth repairing and running. Check the material line before you pay for any repair.

Vests worth knowing, tier by tier

Representative carriers from the armor reference data; the soft class is the vest's own layer, and the plate column shows what the factory or slotted plates provide.

Read the table as a ladder. The PACA is the classic first vest: class 2 soft armor over stomach, thorax, back, and sides, with no plate pockets, fine for scav hunting and nothing more. The 6B23-2 and Korund-VM are the two names every budget player should know, because their plate pockets carry class 4 and class 5 protection respectively while the vest itself stays cheap and common.

At the top end, the 6B43 Zabralo-Sh and the FORT Redut-T5 are the walking-tank options: class 3 soft layers with near-total body coverage and class 5 to 6 plate protection, paid for with serious weight. The Slick sits in a special category as a minimal carrier whose whole identity is its two class 6 plate pockets, popular with players who would rather move fast and trust their aim than absorb extra hits.

Coverage abbreviations in the table follow the game: thorax and stomach are the front torso zones, sides are the ribs, and throat, nape, shoulders, groin, and buttocks are the extended zones that only heavy suits reach.

Plates worth knowing: the real armor market

Effective durability is durability divided by destructibility; it is the honest measure of how much punishment a plate absorbs before it dies.

The plate table below is where smart money lives. Notice that class 6 does not automatically mean best: the NESCO 4400-SA-MC, made of combined materials, posts the highest effective durability in the class at 160, while the ceramic ESAPI Level IV and Granit Br5 reach only 92 and 100 and degrade fast once repaired. The Cult Termite in titan and the GAC 4sss2 in UHMWPE are the endurance picks.

At class 4, the SPRTN Elaphros is the featherweight ceramic option for a hard raid or two, while the Kiba Arms Titan plate roughly doubles its effective durability. At class 5, the UHMWPE GAC 3s15m is the repair-friendly choice. The pattern repeats at every tier: ceramic wins the scale and the first fight, UHMWPE and titan win the month.

Side plates deserve one more reminder: their durability runs only 15 to 25 and they protect nothing but the ribs. Carry them when you expect to hold angles against aimed fire, skip them when mobility matters more.

Match your armor to the ammunition you will actually face

Armor classes only mean something relative to a threat. In the early wipe, most players carry budget rounds like 5.45 PS, which the ballistics data rates as only slightly effective against class 3 and nearly helpless against class 4. At that stage, a 6B23-2 with class 4 plates stops most of what is pointed at you, and spending on anything heavier buys little real survival.

The threat escalates fast. The humble 7.62x39 PS is already very effective against class 4, so AKM-wielding opponents punish mid-tier armor earlier than most players expect. Once lobbies mature into 5.45 BP or 5.56 M855A1, both very effective against class 5, class 5 plates stop being a luxury and become the floor for fair fights. That is the Korund-VM and Defender-2 tier.

At the top of the food chain, 5.45 BS is very effective against class 6 and 7N39 Igolnik at 62 penetration basically ignores it, meaning no purchasable armor guarantees survival against a kitted opponent with top AP ammo. Your class 6 plates buy you one or two extra hits of reaction time, not invincibility. Cross-check any matchup you care about on the ammunition reference page or the ammo chart tool before you spend, because the effectiveness scale, not the price tag, is what decides fights.

Weight, mobility, and when the cheaper vest is the right call

Every point of protection past class 4 is paid for in movement. Full-coverage suits with throat, shoulder, groin, and side protection are heavy, slow your sprint and turn speed, and make you louder to reposition. Minimal plate carriers let you swing on people faster but leave your stomach and sides bare. Neither is correct in the abstract; the right answer depends on whether your raid plan involves holding angles or covering ground.

Be honest about how often your gear comes home. If your survival rate is low, an expensive vest is a donation to whoever kills you, and a cheap carrier with decent class 4 plates plus good ammunition in the magazine will raise your raid value far more than premium armor will. Protection upgrades make sense once you survive often enough to amortize them across multiple raids.

One honest caveat on money: specific armor and plate prices move with every patch and every phase of the wipe, and the research behind this site does not include verified current market prices. Any source quoting exact ruble figures as permanent truth should be treated as unverified. Check trader stock and in-game listings yourself at the time you buy, and compare against the effective-durability math from this guide rather than the headline class alone.

Common armor mistakes that get intermediate players killed

Most armor failures at the intermediate level are process failures, not bad luck. The class label said 6, the durability percent said 40, and the plate pocket was empty on the side the shot came in. Run the checklist below before every raid and you will eliminate the majority of preventable armor deaths without spending an extra ruble.

The mental mistake to unlearn hardest is treating armor as the reason you survived. Armor buys fractions of a second; positioning, sound discipline, and ammunition choice are what actually win fights. Spend your upgrade budget in that order of truth, and let armor be the last thing you overspend on rather than the first.

Expected outcome and what to do next

After applying this guide you should be able to look at any vest in a trader window or on a dead PMC and answer three questions in seconds: what class does it really perform at right now, which of my body zones does it actually cover, and is it worth repairing or is it scrap. That triage skill alone saves more money per wipe than any single purchase.
