Tarkov Ballistics Guide: Armor Penetration Probability, Durability Degradation & Blunt Trauma

Stop guessing why your bullets failed to drop that enemy PMC. Master BattleState Games' complex ballistics formula: armor class thresholds, penetration curves vs plate durability, and blunt kinetic damage through helmets and body armor.

📋 Step-by-Step Instructions

Step 1: Compare Bullet Penetration to Armor Class (The Rule of 10s)

Every armor class requires roughly 10 points of bullet penetration to defeat reliably: Class 3 requires Pen 30+, Class 4 requires Pen 40+, Class 5 requires Pen 45-50+, and Class 6 requires Pen 55+. If your ammo penetration equals the armor class x 10, your first shot has an ~80% chance to penetrate.

Step 2: Factor In Plate Durability Degradation per Shot

When a ceramic or steel plate stops a bullet, it loses significant durability percentage (Ceramic loses up to 22% per hit; Ultra-High-Molecular-Weight Polyethylene loses only 12%). Once plate durability drops below 50%, even budget rounds have a 70%+ chance to punch through.

Step 3: Calculate Thorax Blunt Damage on Stopped Rounds

Even if an armor plate successfully blocks a high-energy rifle bullet (like 7.62x54mmR or .300 Blackout AP), the non-penetrating impact transfers blunt damage directly into your thorax (typically 8 to 22 HP). Taking 3 to 4 blunt impacts will deplete your 85 HP thorax pool and cause death without any flesh penetration.

Step 4: Target Exposed Hitbox Zones (Neck, Armpits, Throat)

Tarkov Patch 0.15 features realistic modular armor plate hitboxes. If an enemy PMC is wearing a Class 6 chest plate, shooting their side armpit or neck bypasses the heavy ceramic plate entirely and impacts only Level 2/3 soft aramid inserts.

❓ Frequently Asked Questions

What is the best all-around ammo for melting Class 5 and 6 armor in Tarkov?

7.62x39mm BP (Pen 47), 5.56x45mm SSA AP (Pen 56), and 7.62x51mm M61 (Pen 64) are the premier armor-shredding meta ammunitions. M61 guarantees first-shot penetration through even the heaviest Class 6 plates.

Does wearing a broken armor plate slow down your PMC?

Yes! Body armor applies movement speed, turning speed, and ergonomics penalties regardless of whether the plate is at 100% durability or completely destroyed (0 HP). Always drop zeroed-out armor in a bush if replacements are unavailable.
