ACE COMBAT 7 - (Mission 9) Easier way to get S Rank in ace difficult

1. Using LACM shooting upper cloud target from long distance away 2. Find warehouse, one LACM can blow up them together. 3. When you kill enough targets, the named F/A18 will showing up. Shoot it down and then finish first part mission. 4. Finish second part ASAP. 5. In my experience, I had been taken 11:51 and got 14250 score. I still got S Rank. So the time spending is not too big problem.
