Dr Passey, some time ago, during the mission in Afghanistan, soldiers were sent into combat for a six-month rotation, and then they came home. However, I have heard that the rotation period is longer today. It is nine months or even longer. So there are two approaches. I think this is because it is difficult to recruit new military personnel and because the mission has been extended until 2011.
In your opinion, is it better to have six-month rotations, and to repeat them more often, rather than having nine-month rotations? What do you think would be the better approach to reduce cases of post-traumatic stress disorder?
