Upon visual acquisition of the target, the Sentry Turret will come to full alert, and the machine guns will emerge.

Sentry Turrets often speak in a sweet child-like, artificial voice similar to GLaDOS and a lavatory bowl within the Enrichment Center.Sentry Turrets are commonly seen serving as (rather ineffective) guards in the maintenance areas of the Enrichment Center, and during testing as an obstacle to the Test Subject. The Aperture Sentry Turret has a single red eye, sleek appearance, and predominately white color scheme common to most Aperture Science technology.The Sentry Turrets are voiced by opera singer and voice actress Ellen McLain. In Portal 2, however, Turrets will only follow the player behind glass. In Portal, Turrets will shoot the glass when the player is on the other side. Additionally, the Discouragement Beams or Emancipation Grills can be used to completely destroy them. This can be done by picking them up and dropping them, or using any object to tip them over. The most common method is knocking them over, causing them to flail and fire wildly before deactivating. Turrets can be avoided, disabled or destroyed in a number of ways. If the latter occurs, Turrets will briefly search for the test subject (as indicated by the movement of the targeting laser), after which they will revert to a standby state. They will continue to fire until the target is dead or moves out of sight. Moving into their angle of sight however, will cause Turrets to deploy their guns shortly after greeting the unlucky individual before opening fire. When test subjects are out of sight from the Turret's presence, they will maintain a standby state and will remain motionless with their guns retracted. Almost all of the space within the Turret is devoted to storing the ridiculously stacked ammo, explaining the nearly infinite supply of ammo when firing. The central part of the chassis holds their red eye, which emits a targeting laser. They are seen as incapable of independent movement, but can open each side of their chassis (their 'arms') horizontally in order to reveal two gatling guns. It is possible that the machine gun is electric powered, as it stops functioning when the power is low.Sentry Turrets are tripod robots that appear in every game in the Portal series.

The Conscript of the sentry gun will sometimes suddenly disappear when the structure is destroyed.When selected, he will quickly drop the bottle, only to pick it up again once unselected. The conscript manning the sentry gun will drink from a bottle (which uses the same model as the Molotov cocktail) when idle.The conscript inside is immune to weapons that would normally kill a conscript out in the open, including anti-garrison weapons, and will only be killed if the sentry gun itself is destroyed.These structures offer a somewhat cost effective resistance against lone commando assaults ( Natasha's laser sight has less range than its machine guns), but are out-ranged by artillery units and defenseless against aircraft.

The machine guns appear to fire armor-piercing bullets, as it is very deadly against both infantry and light vehicles, and can even be a threat to tanks in large numbers. It is basically three heavy machine guns on a 360-degree turning mount, surrounded by brick and mortar and manned by a single Conscript. The Sentry Gun was the Soviet Union's basic base defense structure during the Third World War. Please refer to the talk page for further discussion.
