(QUOTE)
America is a continent and "Americans" cover quite a lot of peoples from varying countries. So since we all have to be so formal and afraid of everyone's feelings, we need to be clear in that it's USN/USAF/USMC for a reason and substitute the often used "American" with "US citizen" or "US warplane."

True, in the sense there are Asians and Africans and Europeans and Australians (dual continent/country) and Americans in the more specific sense of North Americans and South Americans and Antarcticans in the sense of penguins.
But unless there are other nations with "America" in their name, the only Americans based on national name come from the United States of America. It's really USA, not just U.S.
Fun to see official entire names of nations, e.g.,
United States of America
United Kingdom of Great Britain and Northern Ireland
Kingdom of Belgium
Canada
Republic of Finland
French Republic
Principality of Monaco
Union of Myanmar
Sultanate of Oman
State of Qatar
Most Serene Republic of San Marino
Swiss Confederation
Russian Federation
Federal Republic of Germany
Japan ...
and that's where the thread got hijacked (taking fingerprints)....
