El Alamein's Edges:

 Infantry:  Okay, well... let's take a look at the grunts and footsoldiers marching into this battle, then, shall we? The Unggoy and the Buzzers seem equally useless in this fight, but for different reasons. Apparently the Unggoy require a breathing apparatus to survive outside of a primarily methane-based enviornment. As a result, I would hazard a guess that methane levels would be insufficient to meet their respiratory needs in a setting described as "Earth-like." If their breathing apparatuses are compromised, they're done for. Not only that, but their weapons don't have a lot of range on them anyway and they're treated like cannon fodder. Meanwhile, the Buzzers are almost exclusively melee units that are deployed in a similarly suicidal fashion with little to no preservation instinct. These two warrior classes will drop by the droves. Another group of infantry that I think will prove to be little more than cannon fodder is the Disintegrators - at least if they engage in infantry combat.

The Kig-Yar seem to bring a level of frontline competence to the Covenant army. Their abilities to be employed as skirmishers with decent ranged weaponry will prove invaluable if they harass or otherwise hinder the advance of the Scrin military. Since they carry carbines and rifles, they could theoretically inflict a significant amount of damage if they strike hard, fast, and then scatter. The first type of Scrin infantry that seems combat competent, then, is the Shock Troopers, who can hold their own against not only infantry, but also armor and aircraft. It seems that both of these armies' standard troopers have slightly different roles (skirmishers vs. anti-vehiclular combat), but they can do them equally well, making this part a draw.

Next, the Sanghelli and Brutes bring a level of combat competence so far unrivalled on the battlefield. Not only are they sentient, proud warriors, but ones very adept at responding to fluid situations as they occur on the field of battle. The Ravagers seem to function more similarly to the Kig-Yar than anything else, with their projectile-based sort of combat leaving me with the impression that they'd be better suited to ranged skirmishing. The Masterminds seem highly specialized, again, as an anti-vehicular sort of warrior, which could prove useful if the Covenant relies too heavily on their armor in a fight.

Overall, though, the Covenant infantry is much more combat capable in a head-on fight. They aren't nearly as specialized and seem to have a higher level of cohesion and intelligence that will speak volumes for their ability to coordinate and respond to situations mid-battle. I think that will be the tipping point that will have them outmaneuver their Scrin opponents.
