The contra-rotating rotors eliminated the need for an anti-torque vertical rotor, allowing all power to be used for lift and thrust. Its top speed of 170 knots (196 mph, 315 km/h) was faster than 1960s, and even many contemporary, utility and attack helicopters. Its primary roles included troop movement, artillery emplacement and battlefield resupply. There is a wide loading ramp at the rear of the fuselage and three external-cargo hooks.
Chinooks first saw extensive use during Second World War by both Allied and Soviet as infantry transports and ordnance delivery units. After the Second World War, they remained in service of the Global Defense Initiative and Brotherhood of Nod during First Tiberium War, which overhauled their design and made them even more powerful, capable of delivering tanks to the battlefield. Due to cost cutting measures to keep Chinooks cheap enough for battlefield construction, they could only carry a maximum of 5 soldiers.
After the First Tiberium War, the CH-47 and the CH-46 were decommissioned in favor of the Orca Transports. Nod however had decommissioned these units completely.
