The new logo was revealed through a YouTube video titled "LOGO ANIMATION." In the video, you get a buildup until you see two logo's, one for BTS and one for ARMY.

If you inverse the ARMY logo, it becomes one/connects with the BTS logo.

Shortly after the reveal, BTS wrote on their official Twitter: "I really like the new BI [Brand Identity]. I can't wait to show you. Above all, us and army becoming one together has so much meaning that it makes us feel good."

??? BI? ?? ??? ???. ? ?? ???? ???? ???? ?? ????? ????. ???? ??? ??? ??? ??? ???? ?? ??? ?? ??? ????!!
