Another key advantage our military has is training. Our training budgets are much larger than other countries. As a result, our soldiers, sailors, airmen, and marines are substantially better at their jobs than most of our threat-countries (if not all). I forget the exact numbers, but, for example, USAF fighter pilots in Korea fly hundreds of hours per year--more in a month than North Korean pilots fly in a year. It's not just the number of personnel, it's the quality.
Even before the "Global War On Terror," our services spent a lot of time in high-quality training environments. Now, as the GWOT winds down, the services are full of experienced professionals who know how to fight. This isn't something we would aspire to (the 18-year wartime footing), but it has had the benefit of further honing a professional fighting force. Part of knowing how to fight, is knowing how to supply and how to communicate. These are things that our military is currently very good at. It's one of the reasons that the military supply experts are, as I understand it, involved in helping with the COVID-19 distribution of medical resources.
