The bomb emits a periodic beep and red strobe, the latter of which clearly illuminates the bomb carrier's view in first-person view.
Like the flag in Capture the Flag, the bomb's location is displayed to all players, and its status is displayed as a title in the upper-third of the screen and as HUD icon. Possession of the bomb is also shown above the minimap.
The bomb must be picked up on foot, and is only dropped when the player carrying it is killed or reaches an enemy M-COM. The bomb is buoyant—a bomb dropped in open water will float at its surface. If a dropped bomb is not picked up in 30 seconds, it is removed from battle and a new bomb spawn to replace it.
When a bomb is carried, enemy M-COM stations appear with arrow marker icons. If an enemy is carrying the bomb, the team's own M-COMs will appear with shield icons. Upon reaching an enemy M-COM, the bomb carrier is able to plant it (by holding Patrol Boats or Main Battle Tanks, provided they are close enough. Some time after an objective is taken, the bomb will reappear in another random location on the map.), arming the objective. The enemy team has 15 seconds to defuse the bomb or the M-COM will be destroyed. The bomb explosion is very large, and will kill any nearby players, friend or foe. This explosion is strong enough to destroy any vehicle, such as
The Bomb spawns at the attacking team's spawn and is used to arm the defenders' M-COM stations. As players do not respawn in the mode, the bomb will not disappear after a certain amount of time if not picked up. Much like in Obliteration, the bomb's explosion will inflict a large amount of damage to anyone or anything nearby.
- The bomb package resembles that carried by PLR operatives throughout the level "Comrades" in Battlefield 3.
- In Battlefield 4, when the bomb-carrier enters a vehicle, the bomb will be attached to the outside of the vehicle (example: on the back of the Quad Bike). As soon as the carrier leaves the vehicle, the bomb appears on the carrier's back again.
