In the army, the medical files will follow the soldier. As a soldier deploys to his unit, the paperwork that comes with him will come with his medical file. It follows him throughout his tour and is returned with the soldier back to his unit. So there is care of the file from start to finish. It is used consistently as the repository for all medical issues. The medical files are available at all times.
As he transfers from unit to unit, that medical file will also follow him. It is your file that will follow you, from the paper perspective, wherever you go.
As Commodore Bennett has indicated, as we begin to migrate to an electronic system, that will be made even more efficient. There are, of course, issues where sometimes things get lost. It's not unknown that certain medical files do get lost, but they're always found in our system.
That's how we do it in the army.
