UAV Jammer is a second tier perk in Call of Duty 4: Modern Warfare and Call of Duty: Modern Warfare Remastered that will hide a player's location from an enemy UAV Recon. UAV Jammer is unlocked at level 11. UAV Jammer will not have the same effect as a silencer, which in contrast allows a player to shoot without appearing on the enemies' minimap as a red dot. This perk is similar to the Camouflage perk in Call of Duty: World at War. The player's position will still show up if they fire an unsilenced weapon (though only in Hardcore if the enemy team has an active UAV). Therefore this perk is made much more useful as a combination with a silenced weapon. The perk name features as a title in Call of Duty: Modern Warfare 2.
