WMG / Children VS Wizards

There would soon be a Harry Potter fanfiction based on the premise of this film

However, the fanfiction would instead be about the Hogwarts Guard, a non-magical military/security unit which would serve as Hogwarts's analogue of the HAOS Security Force in the fanfiction, defending Hogwarts from Russian agents who are trying to infiltrate the school and abduct its students.
