A Schwarm was a flight of two "Rottes".
The Schwarm leader was foremost with his wingman to port.
To the leader's starboard, was the "element leader" (or secondary Rotte leader) and to the element leader's starboard, was his wingman.
A Schwarm was four aircraft, a Rotte was two. But formed up, appeared as an offset "V" from above (or below).
