Making enemies "flock" to gunfire

[ValentinBk (DayZ) 0]

Hey all, I'm thinking of making a stealth type of scenario and one thing I'd like to do, not sure if that's possible, is making enemies that hear gunfire "flock" to that location and engage any hostiles. Basically I want to put up some stationary units, some patrols, and get them to respond if something is happening in their area, regardless of what their waypoint at that time may be.

Would appreciate help making that, or something similar happen

As far as I have seen around, this script seems to me the one which offers the closest to what you'd like:

Ravage has a "Gunshot Reactions" feature within the Settings module, I guess you could check out it's FiredAlert function for reference.
