Mobile Suit Gundam: Zeonic Front - Simulation 12: New MS Data II S Rank

This is a bit risky my way of doing it, but basically I have 3 teams of Doms and just have them obliterate the enemy intantly. These may be the toughest enemies in the game barring the White Base crew but 9 Doms will absolutely destroy them in seconds. Just act fast and spraybeam what you can for those extra points and you can get an S rank in a minute.
