Hey I got it!
But I did it a little differently...
Force Power: Speed
weapon:Imperial Heavy Repeater
Strategy: Used the force, then ran out IN FRONT OF R5 ( to slow 'im down)
Then fired at the LOW mines, and crawled under the high ones.
I hope this helps any other people, because this is tough area ( until you get it, then it looks easy...)
People who call me 'paranoid' are probably in on the plot.
