The Mandalorian Code, as I see it, living life as a Mando in the mundane world, as we know it. (Please take this witha grain of salt)
Being a Mandalorian, means family by blood and by “adoption” become one. We all have people in our lives that are not our blood, that if it came to it we’d take a bullet for. Clan means a willingness to tell the truth to each other, even in the face of judgment. As a clan we reserve judgment in the face of ALL the facts. As a clan we keep each other’s secrets.
Being a Mandalorian means taking responsibility for your actions and choices. It also means you carefully measure the choices you make against the effect they have on the other members of your clan.
Being a Mandalorian means learning to defend yourself to the best of your ability, within the context of your life, and beyond. Familiarize yourself with the weapons and equipment available to you in your life. This means anything from a bat to a bazooka, all depending on access. At the least it means that you learn to stay out of places that jeopardize you or the safety of your clan.
Being a Mandalorian means being active socially and politically, supporting those people and policies that will guarantee the future freedoms of your fellow Mandos.
Being a Mandalorians means facing life head on, free, sharing it, honorably and honestly.
