By far the most famous unit was JG 3 "Udet" - during the bloody September heavy
bomber raids in 1944, the Magdeburg area was defended by JG 3 wearing exactly
this coloration. 10./JG 300 Mosquito Jägers, stationed at Jüterbog in the
summer-fall 1944 used the same low contrast camo, for night defense of Berlin
from Mossies. Not sure if this unit continued to fly sky blue a/c following
their transfer to NJG 11, but I doubt they bothered to repaint the birds after
the paperwork transfer.
