Many of the 3rd generation's most talented male K-Pop idols are currently away from the music scene for a short while, carrying out South Korea's mandatory military service, required of all males born in the country who are deemed healthy and fit enough. Those who do not meet the physical examination requirements to carry out their duties as active duty soldiers are often assigned to public service roles for a similar duration of time. 

Here's a status update on the military service completion progress of all 3rd-generation K-pop boy groups. Interestingly, two groups from this generation stand out for not having any members who have begun their mandatory duties as of 2024:
