Security Station (Apocalypse)
Should a base come under attack a Security Station will act as a defensive buffer which can assist Agents in defensive fire. Heavy Plasma Gun emplacements are directed down adjacent corridors. The Security Station is designed so that it will not obstruct the smooth functioning of the base. From: Apocalypse Ufopaedia

A security station is used to attack base invaders without having to expose X-Com agents to hostile entities.
An important facility to limit an enemy from exploring your base, and if any are present, limit the chance of losing technical personel. A single base can only support three Security Station facilities at any time during a base defense mission. Any more than three, the active stations will be chosen randomly at mission start, and if those are destroyed, other security stations will not become active.
An ideal placement of security stations would be to surround the Access Lift. If a Vehicle Repair Bay is used, disect the base by having all important facilties away from these two 'entry-points' divided by a choke point of security stations.
A base which does not have any X-Com personel, barracked or visiting, will be immediately destroyed if infiltrated or raided.
