Part of the difference between title X and title 32 is the money. However it is more along the lines of what set of rules you operate under. Title X is federal active-duty service which has rules that are different then title III to active-duty service. Title 32 allows military to work with local civil authorities and report to a governor.
United States code, title X and the title 32 are the two titles you'll hear most often. However there are titles for every jurisdiction. For example the Coast Guard has a title, which I don't remember what it is, that allows them to have a legal jurisdiction in their operating area.
Another US code that I'm familiar with his US code title 50. This is the US code that you must operate under one collecting intelligence from foreign entities.
Sorry if this post is hard to read, I am using speech to text, while driving, while sharpening my knife, while reciting the Airmans crede.
I will see you all down there, good luck everyone.
