It picks randomly from this selection of phrases:
“Unit down at [location] [location number].”
“Unit down at [location] [location number]. All teams respond code three.”
“Lost bio-signal for Protection Team unit [unit name] [unit number].”
“[Unit name] [unit number] unit deserviced. Remaining units contain.”
“[Unit name] [unit number] unit down at [location] [sector number].”
[Location] is the name of the area that you’re in, gathered from key words used in the map name.
[Location number] is a random number applied to the map.
[Unit name] is a random name given to the squad from a selection, and [unit number] is a random number given to the cop himself.
I think it’s:
“Attention please. Unidentified person of interest: confirm your Civil Status with local Protection Team immediately.”
and
“Attention Protection Team. Status: Evasion in progress in this community. Respond. Isolate. Enquire.”
