According to Lieutenant colonel Dave Grossman, author of "On Killing: The Psychological Cost of Learning to Kill in War and Society", Israeli soldiers reacted with uncontrollable protectiveness and aggression after seeing a woman wounded. Further, Islamic militants rarely, if ever, surrender to female soldiers, lessening the IDF's ability to take prisoners. Iraqi and Afghan civilians are often not intimidated by female soldiers. However, in socially conservative environments, female combat soldiers can search female civilians, while children and women are more likely to talk to female soldiers than to male soldiers.
