The Sentry is an Elite Class featured in Battlefield 1.
A kit geared towards survivability and attacking enemy infantry, Sentries are outfitted with thick armor plating that protects the wearer's face, torso and arms from small arms and shrapnel, allowing them to soak up a large amount of damage, but prevents them from equipping a Gas Mask or utilizing iron sights. In addition, as with other elite kits, players will have to stay out of combat for 45 seconds in order for them to start regenerating health on their own.
Following intense air defense, Luca must discard his armor and proceed towards Ferro Fortress. From this point on, he carries a Villar Perosa. At the fortress, Luca encounters enemy Sentries.
The Sentry kit is a Battle Pickup available in certain multiplayer maps.
The primary weapon is either the MG 08/15 (on maps that involve the German Empire, the Austro-Hungarian Empire or the Ottoman Empire), a belt-fed, water-cooled machine gun that is capable of sustained fire, allowing the user to effectively kill or suppress any infantry caught in their path, or the Villar Perosa (on maps that involve the Kingdom of Italy), a twin-SMG arrangement with a low magazine size, compensating through an incredibly high fire rate. Both these weapons, however, are almost ineffective to kill at long range, making it necessary for Sentries to get close to enemies to kill them.
In the Battlefield 1: They Shall Not Pass DLC, the maps Verdun Heights and Fort Vaux offer a selection of elite kits—including one of each Sentry type—in place of the Behemoths featured on other maps.
In multiplayer, the Sentry kit appears in the following locations:
Conquest: Flag B in the camp.
Rush: can be found in the first and second sector.
Conquest: In the ballroom flag C, near the flag.
Conquest: Flag E in the alleyway
Conquest: Flag C beside a wall
Conquest: Near one of the entrances to either bunker.
