Engaged To The Love Of My Life And The Army

My fiancé and I are engaged we look to be married as soon as possible he's deployed in japan right now, and I miss him like crazy but I'm okay! My only worry is that his commander and chain of command will not allow him to take leave to come and marry me and bring me back! I talk to him almost everyday! He such a good man. ..... Am I wishful thinkin to think his commander will let him take leave so early in deployment? Or is their hope?
