The Maschinengewehr 18 Tank und Flieger or MG 18 TuF, is a German dual-purpose heavy machine gun that was designed to fill both anti-tank and anti-aircraft roles. Developed at the end of the First World War, it fired the same 13.25 × 92mm SR or tankpatrone 18 armor-piercing round later used by the Mauser 1918 T-Gewehr anti-tank rifle.
