Well, just because I'm tired of all the "Pre-Marian or Post?" and the "Pre-Mede or Post" questions, I'm going to take a whack at this with a few assumptions.
First Assumption: We are talking the Imperial Roman Army of the Julio-Claudians and beyond, but before the 3rd Century CE.
Second Assumption: We are using the Morrowind and Post-Mede organizations of the Imperial Army (Oblivion either being an anomaly or an example of some sort of Praetorian Home Guard)
Regarding armor, the designs are superficially similar, which is obvious. It's all Pteruges (Skirts) to protect the legs, with greaves and manica (armguards) rather than gauntlets, and either simple tunic/leather combinations, mail (lorica hamata) or plated armor (lorica segmentata). All helmets are... roughly similar to the Roman ones, except the full-face, horse-hair crest Imperial Helmet which looks more Corinthian (300 Helmets). The blades aren't truly gladii, used mostly for stabbing, as they're significantly longer and more adabtable, but we'll put this down to the Legions' nordic ancestry. Shields in skyrim are entirely different, being in the kite shape of your stereotypical viking or englishman.
Regarding organization, again, the links are superficial. Morrowind's inclusion of a knightly order and nobility to the legion actually made it more correct. Equites (literally meaning 'horseman') were the Knights of Rome, placed at some level between plebs and patricians. They formed the cavalry of a Roman legion and were more likely to hold officer positions (centurions, etc.) Before the Marian and Imperial reforms, in the time of the Polybian legions, only knights had access to certain military offices, such as the tribunum militum, the actual commanders of any Roman Legion. Military Tribunes (tribunum militum) were the 'generals' of Legions. The title of Legatus or Legate was that of a Roman General of the patrician class. Social status meant he out-ranked the military tribunes and could command the legions instead. Legates were often chosen to be military governors. The title of 'general' that Tullius has is therefore rather silly. Like this one, Quaestor is also nonsensical. Not because there was no such thing as a Quaestor, but because it was a civilian title given to a civic official that handled financial matters. Auxiliary was the term given to any allied forces helping the Legion that were not proper Legionaires. The commanders of one hundred legionaires were called Centurions. This means, if Skyrim wished to be true to Rome, the rankings should have been as follows: "Auxiliary (you are, after all, an ally in the beginning), Legionaire, Centurion, Tribune, Legate." And all the "Legates" in Skyrim should have been demoted to Tribunes.
In the end, what this boils down to is that Morrowind's Legion was closer in spirit to Rome, even if Skyrim is closer in its terminology. Morrowind's Legion was comprised of troopers commanded by knights, all in military roles. Skyrim's legion is a mish-mash of latin words, led by a general (perhaps a legate or consul?).
When it comes to fighting style and tactics, I believe the fault lies with the limitations of the game. All NPCs are given the same fighting style, so they all tend to look the same and get into a big, chaotic jumble, spinning around each other and limping away as they fight. If the Imperial Legion really was to be Roman, they would march as one and face the enemy with their shields, stabbing more than chopping, and prefacing each charge with javelins (perhaps sustained arrow fire, without thrown weapons). Instead, most legionaires charge into the melee and are promptly decimated by the heavier weapons of Stormcloaks. The tank that was the Roman legion could perhaps have been emulated in spirit if all Legionaires were decked in heavy armor, but instead they mostly share light armor, similar to Stormcloaks, and are therefore easily defeated in most confrontations.
Hope this helps.
