Very true, but IME the real military don't hold up the lines nearly as much as the kids from the Missouri Military Academy. I've been stuck behind them at security, and they are a nightmare, because they wear tunics with no real shirt underneath, and their shoulder cords and buttons are STAINLESS STEEL! They always end up trying to remove the chains rather than removing the tunic because they don't want to go through in an undershirt; it takes forever. However, I looked up their calendar and the OP is safe this year, they leave on the 20th.
I hadn't heard about the impending closing of the second B concourse security checkpoint (95% of my travel is through the East Terminal), but it really doesn't surprise me. That line never did get much action, and with so many fewer flights departing through that terminal, it's probably a luxury Lambert can no longer afford.
