Dispatcher

You may also know Dispatch as The Combine Overwatch, Which you will hear over and over in the Half-Life 2 Series, You know that combine are near when you hear a computer-like voice [sounds strangley like GLaDos] talking, usually saying the reason they are traking you. One good example of it is when you get out of the crashed train in Half-life 2 Episode 2, when you get to the buidling that has the communications in it, after Alyx talks with Eli Vance at White Forest [and old military missle base] and the communication are broken you can hear the Combine Overwatch say something.
