First person in an RTS game?

Recently I've been obsessed with the thought of being able to switch from RTS (or strategy) to some sort of first person mode. I mean especially in 2 ways:

1. An RTS game where you can play as a hero, as if the game suddenly became a hack n slash or FPS game - A game like "Rise and fall: civilizations at war"

and

2. An RTS / strategy / sim game where you can drive a vehicle in first person (Or the very least third person) - A game like "Jurassic Park: Operation Genesis" where you play as a normal zoo tycoon kinda game, but you can fly around and shoot out of a helicopter you control.

Can anyone give some good suggestion for games that have these components? I know games like Battlezone is from a first person view and with RTS elements, but thats not what Im looking for. It has to be closer to the examples mentioned above. Would really appreciate any suggestions!

@jun_aka_pekto: yeah I was gonna say that too. Mind you, the first person combat is bad. But it is still fun to zoom into your base and get your hands dirty

Only FPS/RTS i know of is Natural Selection. But that's more, one player is playing an RTS, everyone else playing fps
