It really depends on what factions your dealing with. If it were Covies vs. The Rebel Alliance, Covies would roll em over. If it were The Empire vs. The Covenenant in an all-out space battle… thats a tough one. Im a huge fan of both series, Ive played all the games for both franchises, and as far as space combat goes, Empire all the way. On the ground however, dem Scarabs would eat the AT-AT’s alive. That’s my opinion, please don’t kill me for it.
