The ROTC program at the University of Kansas is graduating its first female combat arms officer since the Pentagon lifted the ban on women in combat.

The Lawrence Journal-World reports Madeline Wilcox enrolled in the Army ROTC program at the University of Kansas four years ago when women weren’t allowed to be combat officers. So she planned to go into military intelligence. But that changed when the Department of Defense lifted the ban on women in combat.

Her superiors were so impressed with Wilcox’s leadership and athletic abilities they assigned her to be a field artillery officer. On Monday, the 21-year-old Wilcox becomes the first female combat arms officer to be commissioned by University of Kansas ROTC under the military’s new rules.
