On August 5, 2005, PFC Vance left Cherry Point and went to Al Assad Air Base to help with Operation Iraqi Freedom. As part of his Public Affairs job, he rotated to different forward bases controlled by US Marine Combat Forces. He went to Al Taqaddum, Al Qaim, and Al Ramadi, among others.

Original 21 year old (born 8-2-84) JD possibly died in Iraq in 2005, and someone has taken over his identity?

He is the first US senator from Ohio without previous government experience since John Glenn, who took office in 1974.

This is not a believable career trajectory.

Who might have been in need of a new identity that was around 6 feet tall? Just saying.
