Founder of Close Quarters Defense,
Duane Dieter

Developed over nine years by founder and President Duane Dieter, CQD® is an operationally focused system providing the most practical, effective training available. It is based on Mr. Dieter's establishment of various tenets of the system and the belief that a moral consciousness and a positive purpose are an essential foundation in one's life.

tenets of CQD

  1. the system must be designed for the high-risk environment – not sports contests or choreographed actions

  2. when CQD® skills are used, they must be justifiable and used with appropriate force control

  3. all armed and unarmed skills must integrate with no contradictions 

  4. all skills must be accountable and sustainable 

  5. tactics and techniques must be validated under realistic pressure of the encounter, as they are taught

  6. skills must be effective in every situation and environment

As the system evolved, Dieter knew that these skills should only be utilized with conscience, purpose, and for lawful and righteous reasons. He also recognized the inherent value, capability, and advantages that the CQD skills provided and undertook various measures to keep the techniques private and out of the hands of criminals or those who would use the skills inappropriately.

CQD was first utilized operationally when Drug Enforcement Administration (DEA) agents recruited Dieter as a member of the newly formed Organized Crime Drug Enforcement Task Force, which was investigating cocaine trafficking on the Eastern Shore of Maryland. He was locally deputized by the Talbot County Sheriff’s Department and federally deputized by the DEA. Using the CQD System to fight the drugs that degraded his community, Dieter worked with a variety of local and federal agencies. The force control elements inherent in CQD served Dieter well. During many dangerous and violent encounters, not one person whom Dieter trained on the task force was injured, nor was any suspect.

He came to realize that law enforcement was only one part of the fight against drugs. As a result of directly seeing the devastating effects of drugs on children through his DEA service, he established The Youth Club as a way for underprivileged children to be encouraged to develop a positive attitude through activities, guidance, and educational opportunities. His primary concern in creating the Youth Club was the safety of these vulnerable children, so they would not fall prey to the peer pressure and use of drugs so prevalent in their community. The children were exposed to role models within the community who inspired them to become good citizens, teach them self-respect, as well as, respect of others, and give them a true feeling of self-worth.

By the end of the nine-year period, Dieter had developed the CQD System as a fully operational and integrated system organized into Six Divisions, with ten levels and twenty weeks of training. CQD encompasses all aspects of tactical fighting from unarmed, armed, prisoner and suspect control, shooting, internal development and ethos training, physical exercises and conditioning into a Full Circle approach to the individual and team’s tactical capability. The efforts undertaken in developing CQD resulted in a more efficient and effective way to defend against a motivated attacker, while utilizing the appropriate levels of force. Ultimately the system was adopted by some of our nation’s most elite military and law enforcement personnel, and Dieter personally utilized these skills in numerous high-risk situations while attached to multiple federal agencies, both domestically and abroad.
