Next Protoss Unit: Observer
Previous Protoss Unit: Stalker
Sentries are combat drones that are equipped with force field generators and holo-projectors. These deadly automatons are used to bolster the dwindling numbers of the protoss race, and to manipulate the outcome of major battles. Sentries can deploy massive guardian shields that protect friendly units, and reduce the damage they take from ranged attacks. They can also project force field barriers to stall or split up opposing forces. Sentries also have the ability to create hallucinatory images that can draw enemy fire while a real protoss strike force maneuvers into position to deliver the killing blow.
Previous Protoss Unit: Stalker
Units
Sentry
General Strategy
- Light support unit that can attack both air and ground targets.
- Excellent unit to complement your Zealots and Stalkers.
- Can project a Guardian Shield that reduces incoming ranged damage.
- Able to deploy a Force Field that blocks movement. This is very effective to block choke points and separate enemy troops.
- Can be warped into the Battlefield by means of a Warp Gate.
Upgrades
- Hallucination: Allows Sentries to create illusory copies of other units. The copies cannot deal damage and die more easily.
Countermeasures
VS Terran
- Reapers make short work of Sentries; be careful of their Force Fields however.
- Use the Siege Tanks’ range to pick them off from a distance.
- Have a Ghost fire an EMP round at them to drain their energy.
VS Zerg
- Spawn Roaches and use the burrow move upgrade to sneak under the force fields and unburrow on top of Sentries.
- Surround them with Zerglings that have the Metabolic Boost upgrade.
- Use Hydralisks to attack from range.
VS Protoss
- Use Stalkers and focus fire. Sentries are not particularly hardy.
- Researching the Blink ability for your Stalkers will give you a tactical advantage over Sentries’ Force Fields.
- Zealots can kill them quickly, but getting to them can be tricky. Researching Charge helps.

i want ask how working "guardian shield" ?
Thanks
One particular tactic that I've used to great effect great effect is to get a robo bay up, get a warp prism up freom it, and warp in 3 sentries and a zealot. Then drop them behind enemy lines and destroy their production line. If it works, it will cripple them badly. I would say this can be achieved at about 10 mins with moderate timing. This harrass was on the Day9 daily, and was put into practice by a player called SaSe.
while i kill u with my zealots and stalkers
