Not sure why you're making such a big deal out of tanker crews going to WIC.
Given the extensive emphasis placed by the school on 'problem solving' excercises, and on the planning and succesful execution of large-scale air operations, it matters little whether those attending fly the pointy-nose jets that drop bombs and fire off missiles, or tankers etc..
Why does it not make sense to prepare aircrews for war - whatever their MDS - to the best of an air force's ability?
