Our percentage, we say, is about 2% to 5% per every crew coming back from the missions.
We have suffered so far. I served as a commander of the German PRT in Kunduz in north Afghanistan for eight months. I brought home with me four deaf soldiers and 32 soldiers who suffered from post-traumatic stress syndrome.
But you have to always bear in mind that the stress syndromes are not always seen during the mission or directly at the end of the mission. This is a long-term disease. We still have soldiers who were on missions in 1999 in Kosovo who are starting to have post-traumatic stress syndrome today. We have also had to learn to deal with them, because it was not an accepted disease in our society, and nobody thought about those syndromes that came up. It's always the same with those new social diseases, like so-called burnout syndrome or something else like that. We have had to learn to deal with those things.
In 2000, when we had our first facts on those soldiers, we started to do an international study. We had access to the American studies of PTSD. Then we started to educate doctors and also those guys who deal with mental diseases...I'm sorry, I do not have the word for them at the moment. They are trained to deal with those soldiers psychologically as well as on a preventive basis.
