So, you know how sometimes people take pictures of themselves without clothes on? Well, some people in the United States Armed Forces did that, and then they shared those pictures with other people online. This is not allowed because it goes against the rules that the Armed Forces have.
These pictures were shared on a website called Marines United, and some of them were of female Marines. That means that people were looking at pictures of women without their clothes on without their permission. That's really not fair or nice to them, and it's also against the law.
The people who shared these pictures are getting in trouble now because they did a bad thing. They hurt the feelings of other people and broke the rules. The Armed Forces are investigating to make sure that this doesn't happen again. It's important to treat others with respect and kindness, even online.
