— In-game description
The gadget is a small deployable device similar to the Radio Beacon, but is tossed onto the ground like the First Aid Pack or Ammo Pack and is about the same size. Once deployed, the device will make a non-existent enemy player appear on hostile players' minimaps, as well as emitting sounds of gunfire. These will not be apparent to the player who placed it, however; the device will only let out continuous beeps as it operates. The gadget can stick to surfaces as well as moving vehicles.
The device's primary use is as a decoy, distracting the enemy and allowing the player to either escape the area or lure enemies into a trap. One should note, however, that the beeping of the device can be heard by all players, so attentive enemies will be able to tell that they are being duped and may attempt to destroy the device. Spotting a deployed DS-3 will cancel out its effects.
- During the pre-release of Final Stand, the gadget was originally just named DS-3. Like much of Final Stand's new additions, it was renamed to the DS-3 Decoy with the beta release of the expansion.
- The DS-3 Decoy is inspired by the DS-22 Sniper Decoy gadget in Battlefield 2142.
