That's an interesting question because it has an interesting answer. I was deployed as part of Roto 4, in 2007 and I was in theatre at the time when I was told I was going to become part of the trauma system. Initially, I didn't know what it was about.
So I left theatre, and within 24 hours I left Kandahar and was in San Antonio, Texas. I went there on a three-week course, where we were taught about performance improvement and the trauma registry. Then I was delivered back to theatre, where I continued for a nine-month tour.
