Korean sensation BTS celebrated their 10th anniversary in June. Their global fanbase is called ARMY - short for Adorable Representation MC for Youth. The fandom was formed 10 years ago on this day and hence July 9 is celebrated as 'ARMY Day' by fans across the world.

BTS take it upon themselves to wish ARMYs on this day and reminisce on their many memories and enduring bond. The group has been on hiatus since last year to pursue personal travels and musical projects. Two of the members, J-Hope and Jin have also enlisted in their mandatory military service tenure. However, the artists fondly remembered ARMYs' 'birthday' and shared sweet messages for their fans on social media.
