Attack Helicopters

I have heard a lot about the Apache, Tiger, Hind, Hokum, Havoc, and Mangusta. However, I haven’t heard much about the Rooivalk. I believe that it is from South Africa. Does anyone have any infromation on the helicopter? Who uses it? How does it compare the the helicopters listed above?

Here is a link to a photo (I hope it works).
