IOW, more of the same old crap. I haven't read the articles yet, but I'll bet they're going to be National guard, so Governors of "Blue States" can veto the use of "troops" from their states, like California.
A couple hundred "support personnel" has been done before, and we already know it's not enough.
ETA: I read the articles. Mattis not saying where the "troops" are coming from, so I strongly suspect I'm correct: Not Regular Army, but National Guard. SSDD.
