And he's writing a web diary for CBBC Newsround.
In his latest, he tells us about visiting a hospital ship.
Diary entry 20:
I got off the ship! Only for three hours.
We went to the hospital ship Argus which at the time was just a short distance away. A 10 minute flight.
It is like a floating district hospital. Imagine your local town hospital, floating in the sea. It's a bit like this.
Only the staff say they're possibly better equipped than most hospitals.
They can treat almost anything on board. A whole range of injuries.
There are British forces on board. Also Americans, and Australians. All part of the coalition forces.
But there are also Iraqis. Prisoners of war, and civilians.
Prisoners of war
There's a 12-year-old boy on board. With a bullet in his chest. Caught in the cross fire. He's being treated for his injury. His mum is there too.
