A Syringe is a simple piston pump consisting of a plunger that fits tightly in a tube. It is used for many medical procedures that consist of injections, and is usually used with a needle.

The Syringe is a gadget featured in the Battlefield: Bad Company 2: Vietnam expansion, issued to the Medic kit. It is equivalent to the base game's defibrillator, and like the defibrillator, it can be used as a lethal melee weapon.
— In-Game Description
The Medical Syringe is an available gadget featured in Battlefield 1 for the Medic kit. Similar to its use in the Bad Company 2: Vietnam expansion, the Syringe is used to revive downed teammates. It has no effect on active teammates.
When a teammate is downed, a skull icon (colored blue for ally, colored green for squad) will appear above his head. The time remaining to revive him is represented by a draining circle surrounding the skull. After emptying, there are about 3-5 seconds left to revive the player before they cannot be revived anymore and are sent back to the Deploy screen. If the skull is flashing, the player may be skipping revive, and will disappear in 3 seconds.
To revive, the medic must simply stab him with the syringe. No charging is required, allowing for a rapid revive. There is a delay before the user may revive another downed teammate; this delay can be shortened if an Ammo Crate is placed nearby.
Revived players are fully healed and recover to the prone or crouching position, depending on surrounding space. If the player is killed too soon after reviving (estimated to be around 10-15 seconds, or after the revived player earns a kill), they will not be revivable and can immediately skip to the deployment screen. After the penalty period, a killed player may be revived again. Players that can be revived will see the "Next Deployment" option filling, and are shown the distances of friendly medics (capable of reviving the player) on the left side of the HUD.
When a teammate is down, a medic may spot the skull icon to alert the downed teammate that they seek to revive them. The downed teammate will receive a voice signal on their killcam, and the name of the medic will be moved from friendly medics into another list above it named incoming medics.
The syringe is also capable of killing enemies if sufficiently charged, similar to the Battlefield: Bad Company 2: Vietnam variant. This is far less reliable than a melee weapon, however, as it will not always register hits on enemies. An early patch restored damage scaling, allowing the syringe to inflict less-than-lethal damage if it is not fully filled.
Notably, damage from the syringe completely ignores body armor. It is possible to use the syringe for an easy one-hit-kill on Elite Classes.
- Prior to the Battlefield 1 December 2016 patch, the syringe could revive multiple teammates in quick succession, similar to the defibrillator's behavior in Battlefield 3.
