A former Army National Guard member linked to ISIS was arrested after plotting a mass shooting at a U.S. military base in Michigan.

FBI Director Issues Stern Warning After Plot Thwarted

The FBI has disrupted a planned mass shooting at a U.S. military installation in Michigan, arresting a former member of the Michigan Army National Guard with alleged ties to the Islamic State (ISIS). The suspect, 19-year-old Ammar Abdulmajid-Mohamed Said, had allegedly been plotting an attack on the U.S. Army’s Tank-Automotive & Armaments Command (TACOM) center at the Detroit Arsenal in Warren.

FBI Director Kash Patel confirmed the arrest and issued a sharp warning to anyone conspiring against the U.S. military. “Let this be a warning: Anyone who targets our military or conspires with foreign terrorist organizations will be found, stopped and prosecuted to the fullest extent of the law,” Patel said.

According to federal officials, Said coordinated with undercover FBI agents he believed to be fellow ISIS supporters. He reportedly conducted drone reconnaissance over TACOM, provided armor-piercing ammunition and firearm magazines, and instructed the agents on constructing Molotov cocktails. He also laid out details on how to breach the facility and which buildings to target.

Said is charged with attempting to provide material support to a foreign terrorist organization and distributing information about a destructive device. Each count carries a maximum sentence of 20 years in prison if convicted.

Drone Surveillance and Operational Planning Cited in Charges

The Department of Justice detailed that, in April, Said assisted what he believed were fellow operatives with preparations for an ISIS-directed attack. He encouraged the use of heavy ammunition and made logistical recommendations for the assault. One message quoted in the criminal complaint advised, “Everyone have about seven magazines because you don’t want to be in there and run out of ammo.”

The criminal complaint also revealed that Said enlisted in the Michigan Army National Guard in September 2022 and began basic training at Fort Moore in Georgia. He was later assigned to the Taylor Armory before being discharged in December 2024.

Communication between Said and undercover FBI personnel began around June 2024, marking the start of a months-long investigation that ultimately led to the arrest. Investigators say Said believed he was assisting a real ISIS plot and acted with full awareness of the attack’s intended impact.

Director Patel commended the swift and coordinated actions of the Joint Terrorism Task Force and other law enforcement agencies. “Our agents, intelligence teams, and partners acted quickly — and they saved lives,” he wrote on social media. “Well done to all on executing the mission.”

Said is currently in custody as federal authorities continue to evaluate the broader threat environment. The case underscores ongoing concerns about domestic radicalization and the use of military experience to facilitate terrorism-related plots.
