A Security Column is a Building found on the Sub level and Pleasure decks. It is a tower that tracks nearby Peeps and fires on Criminals, Spies, Vermin and enemies. When at War with other sections, turrets will automatically target and fire at enemies, but during peace time you have to manually assign them as targets.
Their range depends on the skills of the security force working in the Security Control.
If you are worried about Skrasher attacks you may want to place these near Sick Bays.
The Ward-N Crimgon 1000 is a state-of-the-art column containing sensors, monitors and detectors. Tough and resistant to attack, a few well-placed Security Columns will make any Station a safer place, and will reassure all law-abiding visitors.
