Does anyone have a good use for cruise missiles? I've only ever built one to see what the animation was like. They seem like a waste of shields since they are a disposable unit. I'd rather use bombers for lethal land since they are not expendable and have greater range (although they can be shot down). The only advantage I see with them is if your opponent has massive AA defenses and you'd rather not lose a bunch of bombers to kill a few units.
