Seems to be part of their ongoing strategy to "not pay any taxes ever no matter what". Which answers the question of which the Septics love more, their endearingly bloated armed forces or their historically low top-bracket tax rates. Who needs an actual army when you can watch movies of your countrymen saving the grateful rest of the world by heroically blowing up flying saucers for a much lower price!
"So yes, our military will be leaner," Mr Obama told reporters, "but the world must know - the United States is going to maintain our military superiority with armed forces that are agile, flexible and ready for the full range of contingencies and threats."
They don't really need the Army anyway, they are surrounded by oceans, friendly powers and whatever Mexico is. Anything they want to blow up they should be using sea-launched Tomahawks, B2s or submarine-borne SEALs for. The Marines can do extraction of friendly nationals if some place goes tits up. The US Army is just there to give dumb politicians even dumber ideas.
With a Marine Corps of 250,000+ they will still be able to "generate " global influence, the national guard(army) seems set to be getting a bundle of brought home kit, that's if it makes it back through the supply chain!
