Soldier is a character who makes a one-time appearance in the Season 2 episode titled "Firestorm".
"Soldier" is the nickname of one of the customers of the desert bar run by Angie where Eddie Donahough hung out. When Eddie started babbling to himself about there being "something out there in the desert", he sees "soldier" and accuses him of staring at him. "Soldier" tries to avoid trouble and tries to calm Eddie down but Eddie comes up to him and grabs him so he pushes Eddie down onto the floor. Eddie gets back up and they almost get into a fight but Dominic and Hawke arrive just in time to separate them. "Soldier" explains the Hawke that he was just minding his business and that Eddie started the fight.
