What about tanks? Say you had one that was fully functional, what would they do to you? Asking for a friend.
There’s quite a bit of functional historic vehicles in private collections.
Quite a bit.
There’s an outfit somewhere here in Texas where you can go and drive and fire tanks.
So, to answer your question: nothing. Assuming you have any required (albeit unconstitutional) paperwork.
People own fully functional tank and enjoy shooting off their cannons at meets like Knob Creek at West Point, KY.
