Alternate timeline
In an alternate timeline in which Nazi Germany won World War II and eventually conquered Africa as a result of the Seventh Doctor and Ace accidentally leaving laser technology in Colditz Castle in October 1944, the Luftwaffe was sent in to quell the Mau Mau Uprising against Nazi rule in Kenya. They proceeded to carpet-bomb the tribal areas and wipe out most of the native population. (AUDIO: A Thousand Tiny Wings)

In the real world, the Luftwaffe were part of the Wehrmacht. This, however, has not yet been explicitly stated within the DWU.
