No. Don't waste your time on this. Find his unit or base and call his commander. I guarantee you will be receiving an extremely prompt payment. In fact I would make one last call/text to the soldier that he has 24 hours to delivery payment otherwise you will be taking the issue up with his commander. I don't think civilians understand the ramifications of a phone call to his commander. Its far far far worse than some nobody small claims court judge could ever fathom bringing down on him.
