It is not the only tool we have. I think my colleagues were very articulate in saying that we have put in many checks and balances. There's the periodic health examination every two years. There's the pre-deployment screening. There's the immediate post-deployment, if there's anything they want to report right away. And then there's the enhanced post-deployment screening that happens three to six months after they have returned, because we know that not everybody will identify immediately or manifest it immediately. But we put in another opportunity to be able to diagnose that, and the questions are geared to identify it.
