The Mil Mi-24 (Russian: Миль Ми-24; NATO reporting name: Hind) is a large helicopter gunship, attack helicopter and low-capacity troop transport with room for eight passengers. It is produced by Mil Moscow Helicopter Plant and has been operated since 1972 by the Soviet Air Force and its successors, along with more than 30 other nations. In NATO circles, the export versions, Mi-25 and Mi-35, are denoted with a letter suffix as "Hind D" and "Hind E". Soviet pilots called the Mi-24 the "flying tank" (летающий танк; letayushchiy tank), a term used historically with the famous World War II Soviet Il-2 Shturmovik armored ground attack aircraft. More common unofficial nicknames were "Crocodile" (Крокодил; Krokodil), due to the helicopter's camouflage scheme and "Drinking Glass" (Стакан; Stakan), because of the flat glass plates that surround earlier Mi-24 variants' cockpits.
