CS2 Armor Penetration Explained
Kevlar is one of the most important buys in Counter-Strike 2. Here's how it cuts incoming damage and why some weapons barely notice it.
What armour actually does
In Counter-Strike 2, body armour (Kevlar) reduces the damage you take to the chest, stomach and arms. A separate helmet protects against headshots from most weapons. When a shot lands on an armoured area, part of the damage is absorbed by the vest and the rest carries through to your health. The vest itself also degrades a little with each hit, so a player whose armour value has dropped to zero takes full damage again.
What "armour penetration" means
Every gun has an armour penetration value, usually expressed as a percentage. Loosely, it describes how much of a weapon's damage survives the trip through Kevlar:
- High penetration (the AWP, Desert Eagle, AK-47): armour makes only a small difference, so these guns hit hard whether or not the target is protected.
- Low penetration (many starting pistols such as the Glock-18): Kevlar soaks up a meaningful chunk of the damage, which is exactly why buying armour on the first round matters so much.
Community testing suggests the AK-47 sits around the high-70s for armour penetration while pistols like the Glock sit much lower, but treat exact figures as estimates rather than official Valve numbers.
Guns that all but ignore armour
- AWP — a body shot is fatal regardless of Kevlar.
- Desert Eagle — very high penetration; a headshot kills through a helmet at most ranges.
- AK-47 — its high penetration is a big reason it one-taps helmeted heads up close.
Why this matters for your buys
If your opponents are likely to be armoured, low-penetration weapons lose a lot of their punch, so a full Kevlar-and-helmet buy can swing a duel. Against high-penetration rifles, armour helps less — but it still reduces flinch and can be the difference between surviving a spray and not.
