I'd like to point out that in Alien, the corporation has no name. It is simply the corporation; though the name for the corp in the sequel film apparently comes from a can with the label Weylan-Yutani (yes, no d); I forget whether or not this was an intentional reference at the time. It doesn't really need a name either - it's the corporation of the military-industrial complex; we know exactly the role such an often ambiguously defined entity plays in a morality play like Avatar.
Also, stj's assertion that the reference to freedom fighters is racist is fairly absurd, for two reasons, the first of which being is it's certainly intentional as ironic (fitting in with, well, every single reference to American foreign policy in the film -terror with terror, shock and awe, humane, it's the language these people use) and also because even if sincere it's not racist.
You can call it jingoist, ultrapatriotic, directly descended from the racial predicate of the White Man's Burden (a poem written in response to America acquiring the Phillippines and an injunction by Kipling for the Americans to follow the British in being responsible imperialists, regardless of how thankless the task is, mind), you could even fairly call it a culturalist prejudice but that prejudice is not a racial prejudice anymore than a prejudice against women is. It can indeed be inclusive of nonwhite races also and that's pretty much the barometer. If black soldiers can impose order on a white populated area like Kosovo, well, we've wandered far off the beaten track of this racist identity.
Also, Mr. Laser Beam, if we gave the film a positive depiction of soldiers we would be introducing moral ambiguity. The film proceeds upon the stark black/white lines you like so much: The only way the soldiers can be seen as good people is if they're fighting on the right side, as indeed Vasquez is (I've just seen the film for a second time, first time I've done that for a movie in theatres since ROTK, did she ever get a name?). I fighting on the side of the bad guys they need precisely as much sympathy as a stormtrooper gets, no? They know what they've gotten into; I can see them smiling when discussing the destruction of the Tree of Souls. At least the corporate sleazebag gets a few close-up shots of remorse so we don't feel too bad that he survived.
Also, I don't know if anyone pointed this out, but the original TNG Vasquez-ish role was in fact Tasha Yar. Hence the 'ethnic' name and origin story for a blonde-haired all-American girl (Marina Sirtis had been cast in this ethnic role but famously the actresses were switched.)
Oh yes, damn, and I love this movie. 3D does strain the eyeballs though, if I see it a third time (possible) it'll be in 2D. In every respect, including the preachy environmentalism, this is a film I would have made as a kid. (Hey, I was a kid of the nineties, raised on National Geographic magazines, Pocahontas, Ferngully, save the whales, that whole shebang. The film's tendentious earnestness itself makes me feel nostalgic.)
