The Luftsturmregiment 40 (LStR-40) "Willi Sänger" (English: Air Assault Regiment 40) was a unit of the German Democratic Republic's National People's Army. It was formed in 1986 by expanding the existing Parachute Battalion 40 with additional air assault companies and support capability. It was directly subordinate to the Land Forces Command (Kommando Landstreitkräfte) of the East German Army. Like its predecessor unit, Luftsturmregiment 40 carried the added title "Willi Sänger," in honor of a famed German Communist and resistance fighter against the Nazis.
