But I think in CivIV they should give 2 or 3 UU.
America:
Minute Man
SEAL
F-15 (or something)
Rome:
Legionairre
(something else)
Modern Legionairre (what if Rome had made it to the modern age)
Byzantines:
Dromon
Cataphract (replaces knight)
(something else)
ect, ect, ect

I would go for either a minuteman or the Supercarrier. Most of the units you talk about are not really unique to the U.S. (even the F15 isn't unique, really, just arguably one of the best jet fighters). B52 wasn't unique, USSR had long-range strategic bombers. Same with Flying Fortress. Tomahawk is just a cruise missile, several other countries have them, they just don't use them as often as we doThe only truly unique units are the super carriers and Stealth Fighters/Bombers, which we alone have, but are included as a kind of 'future tech' that anyone could develop.
Carriers would be a good choice, as no one else even comes close, since WWII most countries have one or 2 carriers at most, and even then only carry a small squadron of planes (12-24 aircraft), whereas our Nimitz-Class and newer carry 72-100+ aircraft. Also, they certainly are a symbol of American power, and coincide with the "Golden Age" of Pax Americana, and are one of the main reasons we are able to project power around the world. Disadvantages are, of course, it would be even harder to trigger a GA than with the F15, and they would be of limited use on a pangea-type map.
Minuteman would be a good one also, as it would probably better replicate the "rise" of america in the early industrial. I would make it a variant Rifleman, and would trigger a GA right around the introduction of Steam Power and Industrialism (Industrial Revolution coinciding with America's westward expansion), very useful, and no other UUs in that time frame. Probably either standard stats, but cheaper (70?). Not really much advantage, a little cheaper upgrade, but then you pay more to upgrade to infantry. I would increase the attack, either 5-6-1 or even 6-6-1 (Guerilla stats) and defensive bombard (First shot since they were expert at ambushes). A good all-around unit, not resource dependent, and draftable, which does replicate the "minute's notice" idea. Actually I really like the 6-6-1, basically an early Guerilla, which they were, to an extent, but draftable and upgradeable into infantry. Pretty historical, and since it is modeled on an existing unit, just earlier, it shouldn't be too unbalancing.
