Tech. Sgt. Catherine Nelson, 921st Contingency Response Squadron security forces squad leader, poses for a photo Dec. 14, 2020, at Travis Air Force Base, California. When she began her career in security forces, she knew the job had been traditionally male-dominated in the past. And although this has changed over the years, Nelson said gender stereotyping can still happen in the military. (Photo by Master Sgt. Liliana Moreno)
