I agreed in part. The problem is scale and the fact that unfortunately, while the Spartans might be able to be a threat to 1 Company of Ultramarines (maybe 1 Chapter), that's not who they'd be fighting. Same goes for the Covenant. They'd be fighting the Guard on the planet and the Imperial Navy in space, not just 1 Company, or even a whole Chapter of Space Marines. Neither Halo army is surviving the sheer enormity of firepower and numbers the mainline Imperial Navy and Guard are putting down. Only Starcraft armies might be able to hold and respond against the Imperium. However, there is a good reason for that...
