Pfc. Monica Brown earned a Silver Star in March for repeatedly risking her life to shield and treat her wounded comrades, displaying bravery and grit. She is the second woman since World War II to receive the nation’s third-highest combat medal. Within a few days of her heroic acts, however, the Army pulled Brown out of the remote camp in Paktika province where she was serving with a cavalry unit — because, her platoon commander said, Army restrictions on women in combat barred her from such missions.
