Does not work. Even tried
car addBackpackCargo ["us_patrol_pack_ep1", 2]
it adds the backpack to the cars cargo, but you cannot take it. What I am looking for is some way of setting a config in my missions description. Also I am using Haris press, and a functionary from the chernarus side.

Here is a demo of what is wrong. When you activate the trigger for the civilian nothing happens, but when you activate the trigger for the military unit, he gets a backpack.
