Tactical alert

From Memory Alpha, the free Star Trek reference

Recognizing the need for a heightened state of readiness aboard the Enterprise (NX-01) in dangerous situations, tactical alert is an alert signal first suggested by Enterprise armory officer Malcolm Reed. When the captain gave the order for tactical alert, the ship's weapons were armed, the hull plating was polarized, and critical systems such as the warp drive were secured. In addition, the ship's crew would report to battle stations. An impact on the hull would also trigger this alert automatically. While in the process of naming the new condition, the terms "Reed alert", security protocol and condition red were suggested. The term "Reed alert" was sarcastically suggested by Commander Tucker the name for the new tactical alert system Reed was working on. It was later dismissed by Lieutenant Reed as being "a bit narcissistic," whereas security protocol was deemed "not very dynamic." (ENT: "Singularity")

By the 23rd century, tactical alert was replaced in Starfleet by the red alert and yellow alert conditions. (Star Trek III: The Search for Spock, et al.)

The Pralor Automated Personnel Unit's utilized the tactical alert status aboard their vessels during the 2370s. (VOY: "Prototype")
