This eliminates inappropriate responses thereby greatly reducing civil and financial liability and instances of abusive actions.

Officer Readiness Training

“Operational” means that all skills taught within initial and advanced CQD courses are applicable to high-risk situations and can be functionally utilized for both personal defense and all aspects of an officer’s duties. Upon completion of the course the individual has attained “operational readiness” and is capable of using the skills appropriately within the scope of the level achieved.

For all courses, CQD provides a high level of accountability and quality control through its Validation/Accountability Service. This service utilizes various methods to undeniably evaluate the capabilities of each officer under the realistic pressure and chaos of the high-risk situation. These methods ensure all personnel undergo the same training and evaluation allowing for true assessment and subsequent remediation and produce a greater depth of understanding and confidence. Various Maryland law enforcement agencies have utilized this Validation/Accountability Service for pre- and post- engagement assessment as well as to evaluate the student's suitability for duty.



Sustainment Training

Sustainment Training is available for course graduates who wish to maintain and strengthen their skills. These courses provide a greater depth of knowledge and include the addition of new skills and drills to ensure the advancement of the officer is continually evolving. Time is allotted throughout the course for questions on all topics, as well as clarification on points that may arise from a change in operational objectives.



Sustainment Representative Program

For law enforcement groups that have an established program, CQD offers training certifications that enable vetted course graduates to become Sustainment Representatives (SR) for their organization in order to maintain CQD readiness at their own facilities. Students will participate in an intense training program designed to provide a deeper comprehension of CQD theories and techniques thereby providing integration and interoperability among all personnel within their unit.  SR’s provide a resident expert to reinforce, sustain, and advance components of the CQD system, thus ensuring a high level of quality and accountability.




Instructor Training and Licensing Program

For those law enforcement agencies that choose to make a commitment with personnel and facilities, CQD has established the Instructor Training and Licensing Program. This program certifies selected and fully vetted individuals to teach components of the system and is designed to provide a progressive, operationally focused, and standardized program of instruction for an entire organization. 

Though the skills of CQD may be utilized as a student learns it, the system is complex to teach with the depth of knowledge necessary to maintain a high standard of excellence. Therefore, CQD employs an in-depth process to produce the highest quality instructors. This process develops the candidate professionally, and instills an ethos in each instructor. In the standard CQD Instructor Training Program, prospective students undergo Forging, Instructor Training, and Validation/Accountability Training, followed by periodic Sustainment Training.



Outstanding. More officials would survive if they had this training. This should be mandatory! – I have been in law enforcement for 22 years and this is the best training I have ever received. As a former training officer I am ashamed at some of the information I have passed on. Thank you.

In my 38-year law enforcement career, I have not been exposed to a more relevant or necessary system of training that will not only develop our officer’s technical capability to its highest level, but also provides character and ethos development...the character and integrity of the program and
its cadre are unmatched.
— D. S.
Outstanding. Best training I have had in my life. Never thought an attack could be trained for with such realism. – Once again, this is the best training that I have experienced. Very job oriented and personally oriented. I would like to continue with the training to advance with further skills.
— B. H.
This training was a true eye opener. I wish we had this training before. Each officer should learn some portion of this training to help them survive on a daily basis.

Dialing up and down” is crucial for law-enforcement and I felt this drill not only tested your ability to respond immediately to the given situation – it also helped us to control bleed-over emotions that often affect us on the street.
— J. W.
The training itself focused on integrated and highly effective techniques that could be executed quickly in extremely stressful situations…The end result is a gained confidence in core skills that allows for an “internal dial” to administer the appropriate force to a particular situation due to reduced stress and much less fear during an encounter. This is exactly the confidence and mindset that is needed for any officer working today.

Great training. I learned more in this week than over the last 20 years of police work.

Over the last four years, NSW Combat Fighting Course instructors have trained with many national and international martial arts experts to insure that we are providing the best training possible. While these experts are top of their field of competitive or “sport fighting” only one offers a system that has relevance to actual NSW mission requirements. That instructor is Mr. Duane Dieter... His CQD system is already being used exlusively by Naval Special Warfare Development Group...
— NSW Official Training Justification
Mr. Dieter has worked closely with law enforcement agencies and personnel for many years. In 1988, he was recruited by the DEA to be an integral part of drug enforcement efforts. He was chosen due to his tactical expertise, his close relationship with local law enforcement personnel, and his extensive knowledge of the area and the community…I cannot emphasize enough what an important and valuable asset Mr. Duane Dieter is to all levels of law enforcement.
