If its surrounded by Asteroids how did they get the units on the planet. I know this one, transports with the beam things but cant the zerg scourges blow up on them and kill them and then they have the infested terrans which kills just about any unit in 1 or 2 hits. So the zerg makes those and the Halo people are done. And wuld the zerg side with the Flood because their almost the same.......... and if a Scorpian=Siege tank scorpian can kill MC in 1 or 2 hits. Infested Terrans kill siege tanks in 1 or 2 hits, and a scorpian kills a halo marine in one hit, same with a shot in the head. So wouldnt the Zerg win right there? Scourges can destroy the Cov Ships because there is so many they cant possibly shoot them all down before they hit especially since they only have that big beam cannon.
Not to mention a dark archon mind controlling an entire ship full of people and a zealot is ten times stronger than an elite. Their shields can take multiple tank shots and since a scorpion is equal to a seige tank then two zealots would easily be enough to take out two or three tanks. As for zerg the zerglings would crush grunts. Zerglings don't run away and they move really fast. Not to mention that they are just plain scary and will rip anything in their way to shreds. Dark templars are another powerful tool. They are completely invisible and can kill anyone with a single strike. A few of those getting behind enemy lines would cause havoc.
In the air the combined power of the terrans, zerg, and protoss will crush anything. A carrier has at least enough fighters to destroy numerous UNSC ships and probably a few covenent before it is destroyed. As many people have mentioned scourges can take down ships with ease and it only takes about five or six scourge to blow up any one capital ship. Considering the zerg would probably be able to throw hundreds of them at an oncoming fleet. There might not be any covenent or UNSC ships left to engage.
Protoss technology is better than Covenant seeing they can survive nukes easily. The Nukes in the games cannot be used as reference because everything is out of scale as far as size goes. I mean, a tank is almost as big as a Star Port and those things are HUUUGE.
But the zerg would completely own this. As I said before, a single Zerg brood, a small one at that, almost completely blacked out a planet. From space, all you saw was a black sphere, no planet. There are simply enough zerg to do that. Terran BC's would most likely beat most UNCS cruisers seeing as they are loaded with nukes, as well as a Yamato cannon. Plus they have rapid fire laser turrets, all that. Yada yada... Zerg take this, sheer number. As in several trillion.
some Calc for Halo ships

Of course, the MAC probably could acceelerate at 12,000 gees and get away with alot fewer of the problems I postulated previously. Momentum is still pretty brutal (3.6e12 kg*m/s 3600 gees acceleration in the opposite direction) but if the hsip is moving at relatavistic speeds, it might offfset that some. KE would be 2.16e19 joules - about 5 gigatons.

According to Wong's asteroid destruction calculator, the AJ guns that melted/vaporized the 3km asteroid fired plasma energy ~200 Gigatons, iirc. That's not including the energy that fired out the side, considering the plasma was changed from a ball into a beam
As stated before Protoss technology is far more advanced than the Covenants,
Think about it:
Siege = Scorpion
Scorpion kills 1+ group of elites in one shot and wounds all nearby the explosion
Siege kills 1 zealot after a couple shots
that means that the Zealots are a shitload more powerful than the Elites
and the Dark Templar cloaking is way better than the Elites as well,
It still just bends light, but it cant be deactivated, only slighty altered...
if you hit an Cloaked Elite they instantly become decloaked
They're blades are also twice as powerful, the only down factor is the elites can lunge
and in space,
the yamato cannons on the BC (also standard laser cannons)
the interceptors on the carriers
and the scourge
can more or less take on the entire Halo fleet and win asteroids or not,
the yamato cannons blast through anything... including rocks...
the interceptors are so fast and manuverable they cant be shot down right away or crash easily
and there are so many scourge they cant all be taken out
long story short, Halo forces would be wiped out right away...
but I say we wait for Halo Wars before we make any more major judgements
the halo forces have no chance 😆
who says a scorp tank is as good as a Terran tank, the Terran Tank first has two barrels, combined with the fact it can transform into siege mode to launch long range blasts of energy, the Terran tanks would simply annhilate almost all Halo opposition on the ground with all the siege guns fireing, also on the ground Protoss Dark archons and Dark templar stealthing around absolutly destroying any elites or covenant infantry. Terran marines are a lot like space marines in Warhammer, their badass, dont mess with them, their like super soldiers.
in Space like said before, Zerg=trillions...the numbers alone would be overwhelming not to menstion scourges can bring down caps in no time, yamoto guns on BC would erase most Halo ships.
Starcraft take it...also if you enter the new Starcraft 2 protoss beam ships and the mothership, then Halo can say its prayers
If anything, in space the Covenant would severely annihilate the protoss. Consider this: Your normal extermination fleet consist of 300 ships. If the Covenant actually want to commit to extermination they send around 500 ships. The offensive forces that were present on Chu Sara in Starcraft were only some 70 ships. To add on to that, the Covenant have a nasty tendency to have point defence weaponry fire at ranges of 300,000km + at the absolute bare minimum. Why is this a bare minimum? Because velocities of point defence weapons on a covenant cruiser are actually stated to be 300,000 km/s while plasma torpedoes have velocities of 150,000km/s. Not only would they have vicious superiority in range they do however have the harrowing firepower necessary to field massive firepower. Remember, most planetary bombardments occur with conventional weaponry. That is to say that each projectile has to have a massive amount of energy to be able to penetrate the crust, burn up the atmosphere, vaporize oceans etc etc. Now most would most likely jump up saying that there not allowed to glass a planet. But do I state that they are glassing a protoss occupied planet? No. I'm merely benchmarking the relevant firepower capabilities of covenant ships(i'm well aware of the OP's "no planet killing" rule). It's not like that kind of massive firepower would only work on planets. Its more then suffice to say that it would have absolutely devastating effects on a protoss ship or even a mothership(which as of Blizzcon has severely hit nerfbait with timebomb, black hole, planet cracker removed). To add on to that the Covenant have vicious sensors, vicious enough to actually smell a ship in slipstream from billion of kilometers away. It's simply more then suffice to say that the Covenant pack a severe superiority in space.
