Rather than calling out the troops, who after all are also humans who can spread disease, why not think about money the government could spend in less destructive ways? They could pass a law that allowed CDC to designate particular counties "at-risk" for particular periods. Any resident of such counties whose cell phone records document that she or he didn't leave her or his home for a whole week during the period could get paid say $1000 tax-free for that week. Sure, it wouldn't be 100% effective, but it would be more effective and probably cheaper in the long run than violent national guard police actions.
