Royal Prussian Jagdstaffel 46 was a "hunting group" (i.e., fighter squadron) of the Luftstreitkräfte, the air arm of the Imperial German Army during World War I.
It mobilized on Christmas Day, under command of Leutnant Rudolf Matthaei, brought in from Jasta 5 for that purpose.
Leutnant Creutzmann was then assigned in from Jasta 43 and survived and served until war's end.
[1] The Jasta flew the Albatros D.Va and Pfalz D.IIIa, but the Fokker D.VII[2] was the predominant aircraft used by the squadron.
[1] The only known surviving aircraft from Jasta 46 in the 21st century appears to be the restored Albatros D.Va owned by the Smithsonian's National Air and Space Museum, noted as being from Jasta 46 due to the squadron's characteristic pine green and yellow diagonal striping on the rear fuselage and tail surfaces uncovered through restoration and vintage photos.
