Rape is VERY widespread amongst the military. I'm not just talking about in Iraq, I'm talking about wherever a US military base is located, across the world, rape occurs. There is even widespread rape and sexual assaults against our own female military personal as well.
Just the other day a coworker of mine was laughing about when he was stationed in Japan, one of his comrades put a gun to a Japanese girl and forced her to perform oral sex on him. This is common. Rape, hookers, drugs, alcohol, violence, etc. is common wherever US military bases are located.
