A video posted to YouTube by user Finest Pupil shows the female military police officer, who is addressed as a "commander" by a voice speaking off-camera, getting into position on the ground as part of an apparent firearms training exercise.

The woman is shown to be bleeding in the video, but the uploader wrote in the description that she was not seriously injured. "The drill instructor could have warned her, and everyone knew that what was about to happen, but nobody said anything," the uploader wrote. "This is how you shouldn't operate a gun," the video's title reads.
