On June 5, BTS unveiled a new logo!
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 [BTS Logo?]. 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."
