Starfleet Jedi

War:
United Federation of Planets (24th Century) vs. Terran Dominion (SC) vs. Rebel Alliance vs. Twelve Colonies (nBSG) vs. Corneria.

Space Battle:
As far as I know, the UFP wins in the space battle of all of these. Having antimatter weapons and phasers, as well as the longest ranges of any of these factions, they can zap the other sides' ships from very far away. The Terran Dominion has a few surprises up its sleeves, with the EMP shockwaves and Yamato Guns, which are nuclear blasts concentrated into an energy beam. The lasers on most TD vessels shouldn't do much to UFP ships, but the plasma beam weapons on the newer battlecruisers would so something. Not to mention cloaked Wraiths. The Rebel Alliance has only a few ships at its disposal, and the loss of the personnel at Hoth was considered a major setback. However, their commanders are competent, and the Rebels have often shown the ability to improvize with technology. The Colonial fleet gets shithammered. Every other faction here has directed-energy weapons, and at least some form of deflector shield. The only thing that the Colonies might have going for them is commander competency, and even that won't help. The Cornerians have Arwings, which are great fighters, and can take a lot more hits than X-Wings, but they don't really have much else. And their millitary (at least in space) was shown to be woefully inept. They relied on four pilots, only two of which were worth a shit, and one who was like Wesley and Jar Jar morphed together to fend off Andross's forces when they were all but overwhelmed.

Space Battle Results:
1st Place: UFP
2nd Place: Terran Dominion
3rd Place: Rebel Alliance
4th Place: Corneria
5th Place: Twelve Colonies



Ground Battle:
Here, the UFP is at a disadvantage. The only ground vehicle we've seen is the Argo Dune Buggy, and that was a very light craft. Granted, they make up for it with phasers, TR-116s, tetryon pulse launchers, isomagnetic disintegrators, and photon grenades, but there's only so much they can do without extreme damage to themselves as well. The Terran Dominion would DOMINATE in ground combat. Not only do they have the Siege Tanks and Goliaths, but also the Thor. That walker is so huge, an SCV has to build it in the game (SC2). The Rebel Alliance is at about the same level of advantage as the UFP, but has the bonus of snowspeeders, which could attack from the air. Twelve Colonies once again have the disadvantage, as I can't say I've seen any ground vehicles. And while the Terran Dominion also gives their troops machine guns, theirs are a lot more powerful than the Colonials'. Corneria, when it comes to ground combat, fares better than they did in space. Aside from a wide variety of infantry weapons, they also have the Landmaster, which is a tank that can also fly and shoot down aircraft.

Well, that's just my take on it. What's yours?

For starters, on the ground, the Rebels may have access to those rare units we only see in the EU. It will give them an edge, along shields and other sensor suites, to attack low tech groups such as the Colonials. However these guys also have typical anti-heavy weapons and their basic rifles are a thousand times more accurate than any crap seen in Star Wars.
The Rebels simply have no choice but guarantee air superiority and move with their heaviest units to blitzkrieg any battalion or pocket of Colonials.

Corneria lacks numbers. Their tech is advanced though, but they just don't have enough of them. It's pitifully low so unless I missed evidence of a huge army, their toys won't help them much. Furries, down.
Starcraft clearly comes out on top here, notably with powerful infantry weapons and support of mechanized units. The UFP is right behind, and phasers will prove problematic. That said the UFP may never find itself isolated in some places like it happened during DS9 if its enemies are so few. The largest foe I can think of in this scenario is the Terran C. and they're not exactly that numerous either.

In Space, Cornerian forces may be able to own some Colonial warships, but from what I saw, even their shields are of limited used. The Colonials simply have enough number to swarm the few Cornerian forces with enough weaker fighters and bombers.

The Alliance fleet isn't particularly huge, and I don't see their fighters ever proving to be a danger to an UFP capital ship (that's a view diametrically opposed to those of SDN).
The TC don't strike me as super advanced in terms of warships, although they have those missiles of doom so eventually they may be able to destroy a few worlds if they get anywhere close to them.

First - Rebel Alliance
Second - UFP
Third - Terran Dominion
Fourth - Twelve Colonies
Fifth - Corneria

Reasoning/Opinions:

Alliance (first vs second)
1. Mon Calamari Star Cruisers outgun most of the federation ships over 3 to 1. The larger Mon Cal ship classes overpower the starfleet vessels by an even greater margin.
2. A squadron of Alliance fighters can overpower the most powerful of Starfleet vessels using far less resources and personal than it's counterpart.
3. The the Alliance manufacturing centers at Mon Cal and Correllia can keep up with anything the Feds can dish out.
4. In ground combat the combination of fighters, speeders, hover tanks, and apparently (sadliy) ewoks...I mean Wookies, plus their large supply of volunteers from around the galaxy gives the Alliance the needed hardware and personal to fight any ground campaign.
5. Ground targets can be softened by planetary bombardment

Federation (second vs third)
1. Starfleet vessels in TNG era have greater range and firepower than the Dominion vessels; the Dominion Battlecruiser is about as strong as the old Federation Constitution at max. Battlecruisers have to move into an atmosphere to engage ground forces while the Fed's or the Alliance can bombard from space.
2. As far as ground infantry firepower goes the advantage goes to the Federation over the Dominion, although the Dominion's heavy calvary weapons are a major threat to Federation infantry, the federation air superiority and transporters will nullify Dominion heavy armor.

Dominion (third vs fourth)
1. The Dominion space fleet is on par with the 12 colonies as far as "standard" firepower goes, however the advantage goes to the Dominion because their fighters can cloak, they use temporary forcefields to protect their forces, and the Yamato cannon tips the firepower category in the Dominion's favor
2. The Dominion's ground forces will crush anything the Colonials have

12 Colonies (fourth vs fifth)
1. They have space superiority with their capital ships vs Corneria's none and a numerical advantage in fighters (that aren't piloted by poor AI)
2. Air superiority will crush the few landmasters that Corneria has

Well, you have to remember that SW ship's weapons ranges are absolutely pathetic. The UFP could zap Alliance ships before they even got in range. ST has planetary bombardment, 30% of the Founder's Homeworld's crust was destroyed in three seconds by just 20 ships. And remember that the Founder's Homeworld was pretty much the size of Earth, so that's no small feat.
I seriously doubt that a squadron of Alliance fighters could overpower a Sovereign or Defiant-class starship. Federation Attack Fighters are more than a match for the sub-kiloton weapons seen on SW Fighters.
As for the Alliance beating the UFP in ground combat, well, ya got me there.

And StarCraft's weapons ranges aren't nearly as pathetic as the game mechanics show them to be. The novels - which are canon - show Battlecruisers carrying out orbital bombardment, and having sensors that can detect small arms fire on a planet several AU away. So don't rule out SC just yet.

As for Corneria's position in this battle, I think I'm going to adjust my opinion on that, seeing how one Aparoid that was taken out by Star Fox (just four starfighters mind you), also destroyed an entire Cornerian fleet. Yeah, Corneria's moving to dead last, because their military redifines woefully inept.
