Why the odd ritual? Because, as Reuters notes, as the most divisive presidential election in recent memory nears its conclusion, some armed militia groups are preparing for the possibility of a stolen election on Nov. 8 and civil unrest in the days following a victory by Democrat Hillary Clinton. While the “threeper” security force say they won’t fire the first shot, but they’re not planning to leave their guns at home, either.

An hour south of Atlanta, the Three Percent Security Force started the day around the campfire, taking turns shooting automatic pistols and rifles at a makeshift target range. They whooped with approval when blasts from one member’s high-powered rifle knocked down a tree. The group operates independently, but is affiliated with a national armed movement that calls for members to defend individual rights in the face of what they see as an overreaching federal government. The movement draws its name from the notion that no more than 3 percent of the American population fought in the Revolutionary War against Britain.

Amid the war games, Hill weighed plans for a possible armed march on Washington if Clinton wins.

He said he doesn’t want his members leading the way, but they will defend the protesters if need be. His group will not hesitate to act if a President Clinton tries to disarm gun owners, he said.

Trump’s campaign has energized militia members like Hill, who admire the Republican mogul’s promise to deport illegal immigrants, stop Muslims from entering the country and build a wall along the Mexico border. Trump has repeatedly warned that the election may be “rigged,” and has said he may not respect the results if he does not win. At least one paramilitary group, the Oath Keepers, has called on members to monitor voting sites for signs of fraud.

“I will be there to render assistance to my fellow countrymen, and prevent them from being disarmed, and I will fight and I will kill and I may die in the process,” said Hill, who founded the militia several years ago.

Trump’s candidacy has emboldened armed vigilante groups to speak more openly about challenging the rule of law, said Ryan Lenz, a researcher at the Southern Poverty Law Center. “Prior to this campaign season, these ideas were relegated to sort of the political fringe of the American political landscape,” he said. “Now these ideas are legitimized.” Over the past week, some prominent Trump supporters have hinted at violence.

“If Trump loses, I’m grabbing my musket,” former Illinois Representative Joe Walsh wrote on Twitter last week. Conservative commentator Wayne Root fantasized about Clinton’s death while speaking at a Trump rally in Las Vegas on Sunday.

Armed paramilitary groups first gained prominence in the early 1990s, fueled by confrontations in Ruby Ridge, Idaho and Waco, Texas, culminating in a militia sympathizer’s 1995 bombing of a federal office building in Oklahoma City that killed 168 people. Their numbers dwindled following that attack but have spiked in recent years, driven by fears that President Barack Obama will threaten gun ownership and erode the power of local government.  The result has been a record surge in gun background checks: a proxy for firearm purchases.

In recent years, armed groups have confronted federal authorities in a series of land-use disputes in the western United States. Federal officials fear more clashes could come after seven militants were acquitted on conspiracy charges for occupying a federal wildlife refuge in Oregon.

The reason for the dramatic spread in militia groups is that many fear Clinton would push the county further to the left. ”This is the last chance to save America from ruin,” Hill said. “I’m surprised I was able to survive or suffer through eight years of Obama without literally going insane, but Hillary is
