BTS is a popular K-pop band with a fandom name called ARMY. ARMY stands for "Adorable Representative M.C. for Youth". The name was established and announced via social media on July 9th, 2013 KST, almost instantly after the release of the bands first single "2 Cool 4 Skool". According to USBTSARMY.com, the fandom name "ARMY" also relates to the meaning of BTS full name, "Bangtan Sonyeondan," which translates loosely to "Bulletproof Boyscouts" in English. ARMY is the military while BTS is the armor, which is a metaphor for how the band and fans will always be together. The fandom has over 40 million members who subscribe to BTS YouTube channel, and more than 30 million follow both the member-run Twitter account and Big Hits official BTS Instagram account. ARMY is known for its mobilization with an unrivaled level of organization, driven by a desire to see the seven members of BTS leave their mark in territories previously uncharted by any other pop act from South Korea. Since BTS debut, ARMYs have used their power for social and political action around the world, raising money to regrow rainforests, feed LGBTQ+ refugees, and more.
