Make a civilian a black op

[Milwot]

How and where do you configure the mission file to designate a civilian as a black op, so that the civilian will be able to hide bodies?

[Kammak]

One way is to edit the config for the unit in question and add the line

"HideBodies=true" (or something similar, don't remember off the top of my head)

Or, you could add the action through scripts to any character, then script moving the body lower and lower in depth whenever it is called.
