    It refers to a 9 line, which is a type of radio comm standard used for casualty evacuation and close air support strikes.

    Making a shirt out of it is a bit strange to me.

      Recruits get hazed in to memorizing the 9 Line in various idiotic ways during basic. Unless you’re in the air force where it’s just strongly encouraged. Regardless, as a result it’s a type of cultural flagstone for service members.
