Assassin

Assassin is a Tier 2 perk that appears in Call of Duty: Modern Warfare 3. The perk renders the player undetectable by UAV Recon, Advanced UAV, Portable Radar, Thermal Scopes, and Heartbeat Sensors. Assassin Pro renders the player immune to Counter-UAVs and EMPs and prevents an enemy aiming at the player from being shown a red crosshair and the player's name.

Assassin does not protect the player from being tagged by Recon or the Recon Drone.
