This may already have been answered, but my quick search turned up nothing.
When did the US Army integrate? Conversely, when did the Navy, Marine Corps, Air Force, etc. integrate?
Thanks.

In theory, it started July 26, 1948 with Executive Order 9981, but it took quite a while for all the forces to achieve integration and some units already were integrated in the Navy.
