Any weapon that can be carried by an infantryman including crew served machine guns is covered by the 2nd Amendment.

The Constitution doesn't limit the right to bear arms to "any weapon that can be carried by an infantryman". Saying that this must be what the Founding Fathers intended, when they easily could have said exactly that if they'd wanted to (but didn't), isn't any different from any other crackpot interpretation that finds no support in the language of the 2A itself.

No, it doesn’t. But any other larger weapons are generally covered under the clause that allows the federal government to issue Letters of Marque.
