How to make an Arc Projectile that is Guided?

[Live4evil]

I want to make a grenade that that is targeted on a unit however I want the projectile to be ballistic so it looks like it is lobbed into the air while still being guided so that it will follow the enemy unit on the way down

I messed around with the mover for like an entire day and i still have no idea how to do this.

Check out the reapers gernade weapon. It tosses in a arc if I recall.
