Check it out the second part. The Bell AH-1 Cobra, called the "Huey Cobra," "Cobra," "Sea Cobra," "Super Cobra," or "Snake" (depending on the model), is an attack helicopter, designed by Bell Helicopter Textron. It shares a common engine, transmission and rotor system with the UH-1. It is now fully replaced by the AH-64 Apache in US Army service, but upgraded versions continue to fly with US Marine Corps, US Navy and several other users. (video downloaded from militaryvideos.net)
