Hey fellas, sorry I've been off of here for a while. The "Metro Dive Team" is a shared resource group between Westminster "Dive 1," West Metro "Dive 2," and South Metro "Dive 3." When South Metro Dive 3 is in district it's referred to as "Dive 31."
Dive Alert Levels are used anytime the Metro Dive Team responds to a call. A Dive Alert 2 classifies any non-human rescue or recovery situation i.e. an animal in the water, unoccupied vehicle in the water, evidence search etc.
A Dive Alert 3 is a human rescue situation where all 3 Dive Units respond emergent. If Dive Operations determines that there's no hope for a person missing in the water, the Rescue will be downgraded to a Recovery and become an Alert 2.
