Battle Hardened is a Tier 3 perk featured in Call of Duty: Modern Warfare
Call of Duty: Modern Warfare
- "Reduce strength of enemy flash, stun, EMP and gas effects. Immune to snapshot grenades."
- — Create-A-Class description
Battle Hardened reduces the effectiveness of flash, stun, EMP and gas effects, acting as a combination of Tac Resist/Tactical Mask and Hard Wired from previous games.
Before the 1.14.0 Perk rebalancing update, it did not reduce the effects of the Gas Grenade, nor did it grant immunity to Snapshot Grenades. The latter effect was moved over from the perk Ghost.
