- "Placed equipment will alert the player of nearby enemies on the minimap. Thrown equipment will paint enemy targets upon detonation."
- — In-game description.
Relay is a trait for Stryker in Call of Duty: Infinite Warfare that is unlocked at level 31. It adds a radar scan ability to all placed equipment, and will locate any targets damaged by the equipment. It operates in a combined effect similar to the Portable Radar and the perk Recon from Call of Duty: Modern Warfare 3.
Relay is completely countered by the perk Cold Blooded, as affected players with Cold Blooded will not register on the minimap when in range of the placed equipment nor will they be painted by explosives.
