How do you add style to units?

Units are given faces randomly. If you wish to give a unit a particular face, use the setFace command. A unit's face can be changed at any point in the mission. If you wish to give a unit a particular face you need to add this code to the description.ext.

class CfgIdentities {
   class John_Doe {
      name = "John Bartholemew Doe";
      face = "Face20";
      glasses = "None";
      speaker = "Dan";
      pitch = 1.1;
   };
};

Notice that there are no spaces in the class name John_Doe. You can then set a unit's identity using the setIdentity command.
