Too bad we allow illiterates to be elected to serve in positions where they can influence the creation of legislation. Letters of Marque and Reprisal allowed cannons at the time. The 2nd amendment says "arms". It places no restriction on the nature of "arms" aside from the suggestion that they are useful objects for a militia whose purpose is to maintain a "free state" i.e. one free of tyranny from foreign or domestic enemies.

and “well regulated” means well supplied and trained.
