The aircraft below are flown by the Marine Corps. The top one is the new Osprey that takes off like a Helo, but the props rotate forward and it flies like an airplane.
All the helos shown below after the Osprey were flown in Vietnam. The aircraft below the Osprey is the CH-53 that is the largest that the Marine Corps flies. Below that is the CH-46 which is being replaced by the Osprey. The Huey and Cobra are below that.
