Staff Sgt. Jackelyn Walker enters the ring to fight Pfc. Gregory Langarica in the bantamweight championship of the finals of the Ft. Hood Combative Championships in Killeen, Texas, on Feb. 16. Langarica won the fight when it was called off in the second round. Walker had to be carried off on a stretcher. Fights during the finals take place in a cage with advanced rules. The Army still doesn't allow women to fight in combat but does let them fight against male soldiers at mixed martial arts tournaments at Army bases all around the country.
