DS-3 Decoy

The DS-4 is a radar jamming decoy device designed during the War of 2020. It appears to be a predecessor of the similar PDS-1 and IDS-1 radar devices employed during The Cold War by both the Pan-Asian Coalition and the European Union.

- In-game description

The DS-3 is a gadget featured in Battlefield 4: Final Stand, and is unlocked for all classes upon the completion of the Eye Spy Assignment.

The gadget is a small deployable device similar to the Radio Beacon, but is tossed onto the ground like and is about the size of the First Aid Pack or Ammo Pack. Once deployed, the device will begin making no-existent enemies appear on hostile player's radar, 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 they're being duped and may attempt to destroy the device.
