Most successful helicopter

What do you people think is the most successful helicopter of all time. I think that it is the Bell UH-1 Iroquois aka, the Huey. This chopper is the DC-3 of the helicopter world. Just think how much combat it has seen and how many roles it has performed. With the new UH-1Y upgrade, the Huey is going into the 21st century with new engines, weapons, sensors, and new looks. In short, it is going in with style.
