"One more problem with increasing the size of the Army: where do you put all those troops? A good number of the bases where troops were stationed during the Cold War simply aren't there anymore. Ft. Ord, CA, the former home of the 7th Infantry Division, for example, is now part of the Cal State University system. And the bases in Germany that once housed elements of 5 divisions are, or soon will be, gone, with a just a couple of exceptions.
Even going halfway back to the roughly million-man Army we had during the Cold War would mean adding another 250,000 troops, requiring another 5-10 major installations. Not sure where you're going to find that-and when you do expect enviro-socialists to protest turning the habitat of the southern tigerspotted swamp tree newt into a tank range. And people who don't want to live next to the sounds of gunfire and artillery, or low flying helicopters."
