That's a total red herring.
I'm not sure the Army, Navy, Air Force or Marines wants a 68-year-old guy with two replaced hips. They didn't take those types in WWII. But I certainly would do my part for a real war, not a manufactured, hopeless fiasco like Vietnam or Iraq.
I also think they could just round up all those so-called patriot whackjob poll watchers/governor kidnappers/Capitol invaders who love wearing camo and carrying their assault rifles with them everywhere they go. If they're so interested in protecting their freedom, maybe they should serve and support the country instead of trying to overthrow democracy.
