Q: Context: The Mil Mi-2 (NATO reporting name Hoplite) is a small, lightly armored turbine-powered transport helicopter that could also provide close air support when armed with 57 mm rockets and a 23 mm cannon., In military tactics, close air support (CAS) is defined as air action by fixed or rotary-winged aircraft against hostile targets, that are in close proximity to friendly forces, and which requires detailed integration of each air mission with fire and movement of these forces., The PZL W-3 "Sokó" (en: Falcon) is a Polish medium-size, twin-engine, multipurpose helicopter manufactured by PZL-widnik (now AgustaWestland widnik)., PZL widnik S.A ("Wytwórnia Sprztu Komunikacyjnego PZL-widnik S.A.") is the biggest helicopter manufacturer in Poland. Its main products are PZL W-3 Sokó and PZL SW-4 Puszczyk helicopters. In early 2010 the factory was acquired by AgustaWestland (since 2015 became part of Leonardo-Finmeccanicas Helicopter Division). , A helicopter is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward, and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of VTOL (vertical takeoff and landing) aircraft cannot perform., The Mil Mi - 3 was a Soviet light - utility helicopter originally designed in the 1960s as a heavier and larger version of the Mil Mi - 2 helicopter . It is also a Russian designation for the Polish - Soviet co-operation on larger helicopters based on the Mi - 2 that could replace the Mi - 4 from 1971 . The project never passed the stage of design . Due to problems in this cooperation , the Poles decided to build a completely new helicopter on their own , designated as PZL W - 3 Sokó . Another helicopter designated Mil Mi - 3 was improved Mil Mi - 1 with four bladed main rotor ., NATO reporting names are code names for military equipment of Russia, China, and, historically, the former Eastern Bloc (Soviet Union and other nations of the Warsaw Pact). They provide unambiguous and easily understood English words in a uniform manner in place of the original designations, which either may have been unknown to the Western world at the time or easily confused codes., Subject: mil mi-3, Relation: subclass_of, Options: (A) aircraft (B) code (C) engine (D) english (E) equipment (F) factory (G) falcon (H) helicopter (I) military equipment (J) military tactics (K) mission (L) name (M) part (N) rotorcraft (O) takeoff and landing (P) time (Q) transport (R) transport helicopter (S) turbine (T) type (U) western (V) world
