Conqueror Oklahoma Drill Problems (Please Review)

Don't hold your breath. To EA, the fact that a handful of people have beaten the drill is proof that the difficulty does not need to be lowered. You'll have to, as they say, "git gud."

Honestly, don't beat yourself up over it. The whole series is one big cheesefest. It has a lot more to do with exploiting flaws in the AI than it does skill.
