True that. We don’t “bear arms” when someone is entering the domicile; we come out firing. And all militia are expected to provide their own rifle for a reason... so that they will always be handy.
YES 7 of my ancestors brought their own muskets to Bunker Hill; one was 70 years old. 7 others rushed to Saratoga in 1777 with their own muskets and pitchforks [automatic bayonet weapons]. They were farmers from Massachusetts.
