Very easy to do:
1) 2 harrier fleets setup: 2 beams lasers lvl2, 1 trit armor lvl1, 1 laser shield lvl3
2) 1 ranc fleet 2-3 ranc's and a gen setup: ranc 4 Plasma batteries lvl1, 1 shock shield lvl1 and what ever armor you can fit: gen setup no weaponds just armor and shields.
First attack with the harrier fleet then in battle run away until the fast ships almost catch you turn and kill them you will have to do this with the second fleet also.
Now that the only ship's left are the battleships attack with your ranc fleet turn the ranc to the side then strafe away from the enemy battleships fly the gen ship passed the right or leftside of the enemy battleships to draw there fire while your ranc get into postions.
done easy now you can insta fix the harriers and the gen that dies take just over 6 minutes to repair -5minutes so realy just over a minute to repair.
