Our History with Active Assailant Research and Training

​

​

• 200,000+ responders trained

• 50,000+ hours of active assailant research

• 15 documented planned attacks prevented following Threat Suppression training and consultation

• 15 documented active assailant incidents where agencies reported applying Threat Suppression concepts during the response

 

Threat Suppression is dedicated to the systematic study of active assailant incidents and the development of evidence-based preparedness, response, and recovery programs. Our work focuses on improving operational performance during high-risk incidents through integrated coordination among law enforcement, fire, EMS, emergency communications, healthcare, and emergency management.

​

Unlike many training organizations, Threat Suppression personnel are not only researchers of active assailant incidents, but also responders. Our personnel have commanded and responded to active assailant attacks, terrorist incidents, and other complex critical events. This operational experience forms the foundation of every training program, exercise, assessment, and consulting engagement we provide.

 

Since 2005, Threat Suppression personnel have conducted more than 50,000 hours of structured research on active assailant incidents, offender behavior, emergency response, and targeted violence. During that time, we have designed and conducted more than 125 integrated full-scale exercises involving law enforcement, fire, EMS, emergency communications, healthcare, and emergency management agencies, including exercises at major international transportation hubs. We have also facilitated more than 150 tabletop exercises for public safety agencies, educational institutions, healthcare organizations, critical infrastructure operators, and private-sector leadership.

​

In 2006, Threat Suppression personnel began delivering one of the nation's earliest formal lecture series on integrated public safety response to active assailant incidents using non-special operations personnel. Since then, we have trained more than 200,000 public safety professionals and military personnel representing more than 5,000 agencies across five continents. Our personnel have also provided consulting services to hundreds of agencies developing or refining integrated active assailant response programs.

​

In 2015, Threat Suppression personnel published the world's first doctoral dissertation focused on integrated active assailant response. Titled Analysis of Records that Demonstrate an Active Shooter Response Plan Utilizing 32 Large-Scale Exercises (Northcentral University), the research examined empirical data from full-scale exercises to evaluate integrated response models and interagency coordination.

In 2025, Threat Suppression, in partnership with Guidepost Solutions, was selected by Oakland County, Michigan, to support development of the independent after-action report for the 2021 Oxford High School shooting. The project involved nine months of structured research, document review, interviews, and subject matter expert analysis. The completed report has become a significant resource for agencies evaluating active assailant preparedness and response. This report is available here.

​

Threat Suppression maintains a vendor-neutral approach to all equipment and technology evaluations. Our personnel have assessed law enforcement equipment, emergency medical equipment, ballistic protection, breaching tools, weapons platforms, acoustic gunshot detection systems, lockdown technologies, mass notification systems, behavioral threat assessment tools, and intelligence collection platforms. More than 100 companies have sought Threat Suppression's input during product research and development. We do not endorse products or accept compensation tied to product sales.

​

Threat Suppression personnel have also supported behavioral threat assessment and management efforts involving individuals of concern within educational institutions, government agencies, and other organizations. Based upon formal documentation provided by partner agencies, Threat Suppression training and consultation have contributed to the prevention of at least 15 planned acts of targeted violence, including planned school attacks.

​

Government agencies have also formally documented that Threat Suppression training provided operational guidance during at least 15 active assailant incidents. These acknowledgments are based on after-action reports, agency correspondence, and direct feedback from incident commanders and operational personnel. In many cases, agencies have advised that concepts taught during Threat Suppression training were directly applied during real-world incidents and contributed to successful operational outcomes.

 

Our company’s flagship course, "Joint Public Safety Response to the Active Assailant" is a structured, research-based program supported by more than 600 cited sources, including a substantial body of peer-reviewed literature. Agencies across the United States and internationally have adopted this course as a required component of responder training.
