Melee: The ODSTs get the edge here, for the stun baton to have a full effect it would have to hit the unarmored portions of the ODSTs, granted the same could be said for the combat knife but it is actually capable of killing.

Close Range: ODSTs again. the 12.7mm round will hit with so much more power than the 9mm round in the combine's USP. Also it helps that by the time the ODSTs are around propellants in the weapons vastly outclass the propellants that we use today.

Mid Range: Draw. The ODSTs have the all around better weapon that is more versatile but the fact that the mp7 has a grenade launcher evens it up.

Long Range: ODSTs. Their weapon is actually an anti-material rifle that the UNSC loves to use as a marksman's weapon. Also the fact that the combine's rifle actually gives away their position, before the shot, is a massive disadvantage.

Special: ODSTs. the M90 uses 000 8 gauge magnum shells where the buckshot, iirc and may be wrong, are DU. Basically the shotgun hilariously outclasses the 00 12 gauge that the spas uses.

Equipment: Eh, the ODSTs get the edge, only because lobbing a grenade that your enemy can quickly spot and avoid is a bit of a drawback

X-factors: Pretty even with a minor edge towards the Helljumpers. Brutality without training is actually a serious drawback. Not to say the combine aren't trained, they clearly are but letting yourself be consumed by a fight can actually hurt more than it helps. Also I'm willing to bet that the armor of the ODSTs are more adavanced, especially in their HUD and comms department.

Overall: The ODSTs take this one pretty handidly. Their wepaons completely outclass those used by the combine. As well as the fact that they hold virtually every edge there is.
