While much remains unknown about the man who carried out an attack in New Orleans on New Year’s and another who died in an explosion in Las Vegas the same day, the violence highlights the increased role of people with military experience in ideologically driven attacks, especially those that seek mass casualties.

In New Orleans, Shamsud-Din Jabbar, a veteran of the U.S. Army, was killed by police after a deadly rampage in a pickup truck that left 14 others dead and injured dozens more. It’s being investigated as an act of terrorism inspired by the Islamic State group.

In Las Vegas, officials say Matthew Livelsberger, an active duty member of the U.S. Army Special Forces, shot himself in the head in a Tesla Cybertruck packed with firework mortars and camp fuel canisters, shortly before it exploded outside the entrance of the Trump International Hotel, injuring seven people. The explosion immediately raised questions over whether it was politically driven, given the location in front of the Trump hotel and president-elect Donald Trump’s ties to Elon Musk, the CEO of Tesla. Investigators, however, have yet to reach any conclusions.

Service members and veterans who radicalize make up a tiny fraction of a percentage point of the millions and millions who have honorably served their country. But an Associated Press investigation published last year found that radicalization among both veterans and active duty service members was on the rise and that hundreds of people with military backgrounds had been arrested for extremist crimes since 2017. The AP found that extremist plots they were involved in during that period had killed or injured nearly 100 people.

The AP also found multiple issues with the Pentagon’s efforts to address extremism in the ranks, including that there is still no force-wide system to track it, and that a cornerstone report on the issue contained old data, misleading analyses and ignored evidence of the problem.
