In the course of traveling in groups or large vehicles, an alert status is used by leaders of service and military organizations to communicate to all members of a unit when readiness for action is needed.

Starfleet[edit | edit source]

The Earth Starfleet began without an alert status system until one was suggested by Lieutenant Malcolm Reed aboard the prototype Enterprise, an early starship that had a larger crew and a greater need for reaction time during crisis situations. Lieutenant Reed's tactical alert utilized audio announcements, including a siren noise which was initially displeasing to other Enterprise personnel. (ENT episode: "Singularity")
