That's nonsense in my opinion.
Only possible if only a few are left.
With millions unvaxxed, you can't do that, because when too many defend themselves, the squad gets smaller and smaller over time. "Just doing my job"-types are stupid, but aren't that stupid to not notice that they will be next. It doesn't work that way.
Always remember Afghanistan not only beating the Russian military, but also the US military with a few AKs.
