German ace Werner Mölders and Vierfinger or “finger four” formation

During WWII pilots were still trying to figure out what is the best tactic to use during dogfights. The lone wolf tactic wasn't helpful because it usually turns into a 2v1 contents; the tight formation and everyone for themselves doesn't work because again its easy to be 2v1. But during the war German ace Werner Mölders figured out the "finger four" formation. Even though it is up for debate as to who was the first person to actually create it, there is no doubt how important this aviation tactic has become.
