A Colorado man was arrested on April 3 after attempting to enter Peterson Air Force, home of U.S. Northern Command and NORAD, in what law enforcement officials characterized as a “minivan loaded with propane tanks” — the latest in a series of bizarre security incidents involving military installations across the United States in recent months.

El Paso County Sheriff’s Office spokeswoman Jacqueline Kirby told Air Force Times that the suspect in Tuesday’s incident barricaded himself inside his vehicle amid a “mental health crisis,” and that police did not identify any “explosive material” beyond propane tanks strapped to the van’s roof when the vehicle was stopped a half-mile away from Peterson AFB’s north gate.

But the incident came less than two weeks after 51-year-old Hafiz Kazi, a legal immigrant from India who has lived in the United States since 1993, drove a burning vehicle loaded with propane tanks and one-gallon containers of gas to the main gate of Travis Air Force Base in California. (The FBI told Task & Purpose that there was no evidence to suggest any connection to overseas terror groups.)

Indeed, several military installations across the continental U.S. have endured alarming threats or attacks of various intensity in recent months:

  • On February 14, three men managed to breach a gate that leads to the National Security Agency’s main complex at Fort Meade, Maryland — the Army base that’s home to the NSA, U.S Cyber Command, and Defense Information Systems Agency. Authorities said there was no terror connection.
  • On February 22, an unidentified man rolled up at the front gate to Naval Base Kitsap in Washington State, claiming that both his SUV and his body were loaded with explosives. The idiot was immediately apprehended, but it’s worth noting that Kitsap is home to the DoD’ssingle largest arsenal of strategic nuclear weapons, as well as its single largest fuel depot; a month later, the Trump administration would announce the closure of the Russian consulate in nearby Seattle, explicitly due to its proximity to the installation.
  • On February 28, first responders rushed to Joint Base Myer-Henderson Hall in Virginia after an “envelope containing an unknown substance” ended up sickening at least 11 personnel with symptoms ranging from burning sensations to nosebleeds. The letter, “described as irate, and at times unintelligible” according to Time magazine, was reportedly addressed to the base’s commanding officer.
  • On March 27th, federal law enforcement officials arrested 43-year-old Thanh Cong Phan on suspicion of sending several suspicious packages containing explosive materials to multiple military installations in the Washington area, including Joint Base Anacostia-Bolling; Fort McNair; Fort Belvoir; and the Dahlgren Naval Surface Warfare Center. Law enforcement officials described Phan to Fox News as “emotionally disturbed and no stranger to federal and local authorities.”

Including the Tuesday kerfuffle near Peterson AFB and the fiery crash at Travis AFB, that’s six alarming incidents in just over six weeks at CONUS military facilities. And while none of these examples appear connected to any sort of foreign terror, the frequency of such bizarre incidents may leave some service members (and their families) on edge.

It’s unclear at this point if the DoD has pursued any policy changes regarding these recent incursions. The last time NORTHCOM publicly altered its force protection condition for a non-specific threat was in May 2015.

When reached for comment by Task & Purpose, a NORTHCOM spokesman said he would examine existing guidances distributed by the command in recent months to see if military leaders had explicitly addressed the uptick in incidents.
