UNSC. Spartans are armies within them selves... A squad of them transferred a high priority package across a planet and another saved a planet... Plus UNSC weapons and vehicles are stronger than Terran Republic's... Also the high power sniper rifle the UNSC use can severely damage a tank or even aircraft.... Now if they were facing Vanu that's like almost facing the covenant which i think the UNSC would lose against....
