Warning if player kills civilian

[Binary]

Hey folks !

I'm wondering what would be the best way to go about this..
I have a mission with a bunch of civilians placed around the map - and I'd like to display a sidechat message if one these are killed..
Just a simple:
"A CIVILIAN HAS BEEN KILLED ! CHECK YOUR FIRE!" or something.

Is there some way to associate this with every civilian ?

Edit: Anyone ?? 
Sorry to bump - I'm just really unsure how to achieve this

add an eh to every civilian


ie   this addEventHandler["killed",{_this execVM "warning.sqf";}];

warning.sqf

Code: [Select]

_killer = _this select 1;

_killer sideChat "STOP KILLING THE CIVILIANS";


[Binary]

Sounds like a sensible option

What about performance impact, if using it on a lot of units?
It would only really take up resources, once the unit is killed, right ??
