The Kevlar Armor/Helmet is the equipment for both teams featured in Counter-Strike: Source. This armor reduces damage significantly, and if weared with an helmet, you are protected against most instant kills which are very common if you are unarmored.
Armor should always be bought if playing in the zombie escape gameplay! This will protect you against many types of damage (fire, electro, slashing, ...) and also protect you against explosions caused by bosses.
- The Counter-Terrorist player-models will always look like if you had armor and a helmet by default, even when not buying any of them.
- Likewise, the Terrorist player-models will always look like having no armor, even when buying any of them. You will visually not be able to see a helmet on their heads.
