PROELIA Defense & Arrest Tactics

PROELIA Defense and Arrest Tactics is a complete system for all law enforcement, loss prevention and security personnel developed by working cops and based on the needs of the end users; the officers and deputies on the job who use it. It has been taught to law enforcement recruits and in-service personnel with great success for several years.


PROELIA Defense and Arrest Tactics is a constantly evolving and adapting system based on Human Performance Science, how the body reacts and performs under real world conditions. It is not an overly complicated system of multiple techniques dependent on fine motor skills. Rather, it was designed to facilitate the application of gross motor skills, and is based upon reoccurring principles that can be applied to a wide variety of situations. It has been proven effective with officers regardless of size, strength, gender and level of training.

The techniques and methodologies of PROELIA Defense and Arrest Tactics are currently being taught at several law enforcement academies including the San Jose Police Academy and the South Bay Regional Public Safety Training Consortium. Several bay area agencies have adopted PROELIA Defense and Arrest Tactics for their in-service training.
The developers of this system have decades of real law enforcement experience including patrol, special operations units, covert investigations and more. They have been instructing defense and arrest tactics to academy level and in-service personnel for over 10 years. They have been nationally published in use of force and defense & arrest tactics in both magazine and on-line articles.
PROELIA Defense and Arrest Tactics is much more than a list of techniques. We have a philosophy and methodology that emphasizes developing a strong foundation in the basics through multiple drills and learning activities. The system allows the officer to grow in skill level as the officer becomes more skilled in the basic competencies.

Client Testimonials

Ed Flosi is the consummate professional with a strong work ethic, high moral standards and an eye for detail. Ed has established himself as an expert in his field and a go to person for law enforcement subject matter expertise. His retirement from the San Jose Police Department is their loss and the private sector’s gain.

I give Ed Flosi my highest recommendation as a defensive tactics and crisis intervention team (CIT) trainer. He truly grasps the interface between public and officer safety, particularly as it applies to the emotionally disturbed and the mentally ill.
