This applies to businesses too, not just the armed forces. Here in the US, I'd bet you many businesses, even those that have some measure of emergency disaster preparedness, had not made any plans around a plague disrupting their China-originated supply lines, much less that same plague hitting this continent. But some had. I can't find the link ATM, but a month or so ago, there was an article here on HN, about how a grocery chain in Texas had managed to keep their stores stocked and their supply chains running, in part because they had gamed out a pandemic scenario and made plans accordingly. Some businesses in my have area managed to become (more-fully) operational sooner than others as local COVID-related restrictions have been eased. And others are still completely shut down, even though they could start operating partially again under the current restrictions. Dollars to donuts, I'll bet the many of former had gamed out pandemic or similar scenarios, and planned accordingly, while many of the latter had not.
