How are subsequent Combat Action Badges Awarded? - orders for the combat action badge

So I have two trips to OEF. My first mission, I got a taxi. The second was wounded in combat and received a Purple Heart, but my unit was told that you have a car I do not have. Now I understand later the fight against the plates were stars. So my main question is ..... My unit should submit the documents to get a "2" to cabinet? Do we need to use the stars? Please quote reference thank you.
