My Army service was in a medical capacity. My experience belies any claim that the United States government cannot supply quality medical care. United States military medical treatment is the equal of any other, and the trauma care is the most advanced in the world.
In the military model economy of scale is paramount. As the nation's largest customer for medical supplies, the military has tremendous purchasing leverage. Treatment is standardized, everyone has the same training, and all hospitals are on the same networks.
A military hospital has is no billing department, which occupies about 25% of the staff and the space in a civilian hospital, to pay more people in office buildings elsewhere. There are no stockholders or HMO executives in the chain of command demanding a cut for handling a transaction. Every alcohol swab is not a $5 line item on a bill. If you are on active duty or a dependent and you need care, you get it and all you need to show is an ID card.
Ironically, this is also the national medical model used by every industrial nation other than the United States. This means that other countries are in a position to deal with every infected person during a pandemic, while ours assumes that tens of millions of people who can't afford medical insurance will avoid treatment and continue to be a pool of undiagnosed and untreated pathogens.
