Joining US army for papers is no different and should not be any different than Joining Microsoft for papers. You do not join micro soft for the love and loyalty for that corporation. Microsoft is willing to sponsor you for the labor you are willing to give them and US Army is also willing to sponsor your papers if you are willing to give them your labor for the way they want it.

I hear too much crap about love, patriotism, emotions, and pride. Its a business and should be treated as a business transaction. Weigh out your risk/reward and make a decision.
