I have the M47 Dragon completed. This is the ultimate in AI/vehicle destruction. I can take out Peace Walker custom in about 5 minutes with it and the custom vehicles are a breeze. Currently developing the minigun. I have maybe 90% of the weapons either finished or ready to research.
With the Fulton Launcher and Battle Dress w/Helmet I can basically run around, Fulton all the escorts in a vehicle mission, pop the vehicle a few times with the M47, and cap the leader with the Fulton Launcher. Easy S Ranks.
