Hi,
I posted the question without being registered first, then i registered in the Forum.
I don't have a context. I just wanted to know the rule how to use it and at what times. Could you please help me with the rule?
THanks!

It's still going to depend on context. However, some examples:
(First, personally, I would always use a full stop after each letter, but I expect you'll get a lot of differing commentary on this.)
I live in the U.S.A.
The item in question is made in the U.S.A.
That piece of clothing is U.S. Army issue.
As you can see, if you were to use the word "the" in speaking, it might well fit when writing.
In the third example, your full term would be United States Army. The word "the" is not needed in that sentence. However, by comparison:
The U.S. Army recruits many young people.
That one does need "the."
I'd suggest trying both, and attempting to judge the result on how it sounds read aloud. It won't solve everything, but it will help guide you to some extent.
Good luck!
