Which was the first RTS game that introduced Hero Units?

I’m obsessed with the Hero Units in Real-Time Strategy games. They are such powerful characters and have helped me to win several battles. But I'm curious, which game had the Hero Units? I just want to know a bit of the history. Thanks.

If I'm not mistaken, I think some old games like Herzog Zwei and Warcraft started the Hero Unit idea first. But the game that made them popular is Warcraft II. The Hero units have unique powers and are so helpful in intense battles.

It's got to be Warcraft II. It makes Hero Units a big deal. Another game that used the Hero unit in the early days is Age of Mythology. You can choose some heroes like Achilles and Odysseus. They're super strong and can be used to boost your army's spirit.
