CRepublic of Korea Staff Sgt. Kwon, Minzy, infantryman with the ROK’s 21st Division, tests on the chemical, biological, radiological and environmental lane during the Expert Infantryman Badge competition on Camp Casey, South Korea, Oct. 22. Minzy along with Staff Sgt. Kim, Min Kyoung are the first women to earn the badge in the ROK. The EIB is a grueling two-week course that has historically only been offered to males in combat arms specialties. With current policy changes and many women now filling combat roles, women are now eligible to compete for the badge.
