I know this is completely off topic but Im curious...Are Marines really allowed to own, hold, and brandish personal firearms?
where I live all adults who have not been convicted of a felony are allowed to own, hold and brandish personal firearms under lots of conditions, including in a personal residence.
in addition, they are also allowed to shoot you if you are coming into said residence and there is reason to believe that they are in "grave danger of death or serious bodily injury" at your (the trespasser's) hands.
breaking down my door with a sledge hammer certainly met those conditions.
