Create-A-Class description

Battle Hardened is a Tier 3 perk in Call of Duty: Modern Warfare. It 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. It is unlocked at level 26.

Before the 1.14.0 Perk rebalancing 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.
