If it helps any...
My nephew Dustin (ARMY) was stationed in Okinawa for 8 months. He went there for training and loved it. He kept in touch via Skype & email. His home base is in Hawaii and said he would rather be in Okinawa...so it cant be too bad
He is actually home for pre-deployment leave right now - he is being deployed to Iraq on July 17th. I know how it sucks every time they leave...but this one feels worse IMO. I'd rather have him go to Okinawa again.
I will keep your brother in my thoughts....with the rest of our soldiers
