your forgetting that the unscmc is a self supporting unit with armor/tanks and aircraft support from fighters and bombers as well. so IG infantry alone is screwed against  the marines because all their support is independent of the unsc navy. although i do amit the unscmc has far less aircraft than the navy but its still much better than the IG infantry who has to rely on other IG units for armor and artillery, And the Imperial Navy for air support  which means the IG alone against the UNSCMC would end with the IG being bombarded to death from the air by the marines  aircraft. which would take air superiority due to being unopposed by the Imperial Navy which is the only reason the marines could take air superiority. because lets face it the UNSC has better designed aircraft than the imperium but lack the numbers to elimanate all the imperial navies aircraft in dog fights. so yeah the IG gets screwed by its lack of an airforce to protect them.
