Of course military planes do NOT have civilian registration schemes. (Except for some planes, usually transport, meant ot fly internationally quite often, and where a civilian reg will help get an allowance / reduce paperwork. )
As for tour “example” on us planes: you will have different numbering for usaf (YY-XXXX where YY = Fiscal year of ordering, XXXX being a sequnece number), and the navy, with BuAer numbers. And so on.
If you could now stop trolling, I’d greatly appreciate it.
