Bazookas, so 1940 tech. How about Javelins or a M142 HIMARS set up? Or a M1A3 MBT? Heck, I’m sure someone would demand the right to a Russian TOS-1A since AK-47 are plentiful or even a AK-74M.
During the revolution, private citizens had warships with cannon. Heck, Paul Allen had a bunch of tanks and war planes.
