In my reading about the German pilots, I've noticed that Georg Strasser is often refered to as the wingman of
Julius Buckler. I'm curious about what is meant by that status. If they frequently flew together, then presumedly they used specific tactics to exploit their individual strenghts. My question is whether they were an early example of the WW2 rotte, that is, one of them being the shooter and the other the protector. Also, were there other two man teams other than the famous Luke/Wehner combination?
