Mount Vernon Militia Men

From The Dan VS Wiki
I've got me a musket

The Milita Men are characters from George Washington, serving both as replicas of the real militiamen of the revolutionary era, and as guards of Mount Vernon

They are first seen when Dan attempts to blow up Mount Vernon, Elise taking careful note of their patrol cycles and informing Dan of when a gap opens(though she had already tampered with his explosives prior and turned them into fireworks)

An entire brigade of them show up at the end of the episode to attack Dan and Chris, managing to encircle them. They would have succeeded if not for Elise helping them make a getaway.
