Manning the US border doesn’t require a massive number of new border agents. Reposition some regular force units near the border and make border patrol part of their training and responsibility. Maintaining a perimeter is a vital defensive skill as we’ve seen in Iraq and Afghanistan (and sadly we’ve seen the tragic consequences of infiltrations into the “green zones”), so the training won’t be wasted.
