Bring many anti-Alien units and Barrier Breakers, such as Catellite, Seafarer Cat, Chill Cat, etc. Remember to bring some Long Distance or Wave Attack units because there are several backliners, such as Corporal Weyland. Golfer Cat is a good choice to break Ribbo's Barrier due to his Long Distance ability.
