A rare snow day in Puget Sound, Washington State called for an epic snowball battle between Duvall police officers and a group of local kids.

The video of the showdown, which has since gone viral, shows policemen pulling up to the scene in squad cars. The officers repeat “No mercy, boys, no mercy!” as they take on a “group of hostiles” but eventually retreat as the kids’ firepower turns out to be too much for the cops.

Check out the video, which was posted on Duvall PD’s Twitter page, below:
