Halo 3 Mission 4 First Objective Tips Anyone?

[The Apprentice Programmer]

I'm on the fourth mission of Halo 3 on the first objetive - to remove those wraiths from the picture. However, I suck at the game.

I'm stuck in the last bit of that objective. Theres a cave full of Brutes and two ghosts driving around, and I cant kill them. I can the brutes most of the time, but then the ghosts kill me. I cant kill them because I cant shoot the drivers.

HELP?
Forgot to mention, I'm on normal...

easiest way to take care of a ghost is to throw a grenade at it. when they go for you, jump and throw one of the sticky ones at the same time. if they're shooting you, take cover and throw normal grenades till they either go for you or die. btw, what difficulty are you doing it on?
