I don't know - but I do have a friend who was sad that he had been promoted to trainer just before Operation Desert Storm and never had the opportunity to fly a sortie in his bomber. We
are trained to do something, or we have acquired the right tool for something, and that training or tool wants to be used. the more we have invested in the training/tool, or the more in our way it is, the sooner we are likely to put it to use.
Nearby steel mills remind me of the shipping and oil that passes through this area that has fueled Chicago since its founding. Protecting oil is why we engaged Iraqi troops twenty years ago.
