A look is not sexual assault in the real world. But we're not talking about the real world. We're talking about law, and military law to boot.
Punitive Articles of the UCMJ -- Article 120, Rape, sexual assault, and other sexual misconduct.
A look is sexual assault if the victim claims the look placed her in "
a state of fear". At best the "
perpetrator" is looking at an article-15 for indecent conduct. More sever penalties if the look was sustained, shared by buddies, if alcohol was involved, if physical gestures or comments were included; and the state of stress the "
victim" either experiences or can convince her superiors she experienced, and the political swing of those superiors.
This is how the law is carried out. If a female complains that you looked at her, you're in deep ****, even if you never did look at her at all
(God help you if you did something and she's taking it out of proportion...she will be believed every time, and you will be punished for more than what you actually did).
Of course all of this does absolutely noting to help further integrate women into the service.
