Wikipedia states that:

The Congress of the Confederation created the current United States Army on 3 June 1784.

But how much was it truly a federal force? I assume it had one central command from the start, but on the lower levels, how much was it really a federal force, as opposed to individual US states' armies?

My recollection, from movies, is that during The American Civil War, from 1861 to 1865, the units were still drafted and organized at a state level; you have 1st Ohio Infantry, 3rd Missouri Infantry, etc. And that is nearly a century after independence!

More details on Wikipedia: list of American Civil War units by state versus US regular army; if the latter can be considered the truly federal army then it was clearly a minority.

And then you have movies from Korea and Vietnam, where the units were put together from all corners of the US, no more Ohio or Missouri infantry. When did this transition happened?

Are there still remnants of some per state divisions today?

I am mainly asking because if the EU Army is ever going to happen, how much far behind it would be compared to the US ;-)
