Crazy Joe is incorrect and is misleading the public. If.. IF you have the money you can buy a disarmed F-15 (or other military aircraft), M1A1 Abrams tank (or any tank for that matter) and you CAN buy fully automatic weapons. Plenty of civilians who go through the ATF, jumping through hoops own these types of weapon systems…
Go to any airshow and you will see military aircraft OWNED by civilians. I have to use celebrities as an example because they have the money but Arnold Schwarzenegger owns a tank…
Michael Dorn (Star Trek TNG) owns an F-86 Sabre 
Biden is dead wrong.
