Does Mirko Cro Cop Train In Kickboxing?

Hello, I have always thought that Mirko Cro Cop is a Kickboxer and that his main style of striking is Kickboxing. But I went on the Pridefc and the K1 offical websites and saw that his main form of striking is Muay Thai. So is his main form of striking Kickboxing or Muay Thai?
