Tacmed Shield 4Distributed Security, Inc. is an NAEMT (National Association of Emergency Medical Technicians) Training Center with the ability to offer tactical medicine training worldwide. 

An NAEMT TRAINING CENTER is an organization (which may be public, private for-profit, or private non-profit) that provides initial and/or continuing education to EMS practitioners and other prehospital healthcare providers that has been approved to conduct NAEMT courses. DSI will offer TCCC, TECC, and LEFR-TCC. Tactical Combat Causality Care originated from lessons learned from the wars in Iraq and Afghanistan.

Below are the courses we currently offer. 



  • Target Audience: Non-medical
  • All DSI Students
  • General public
  • Level:Tier 4
  • Duration:1-2 hours

Today we live in a world where terrorism (decentralized/distributed/asymmetric war), the actions of unstable people, and the dangerous impulses of friends and relatives are very real and becoming increasingly more frequent.

Massive bleeding from any cause, but particularly from an active killer or explosive event where a response is delayed can result in unnecessary death. Similar to how the general public learns and performs CPR, the public must learn proper bleeding control techniques, including how to use their hands, dressings, and tourniquets. Victims can quickly die from uncontrolled bleeding, within five to 10 minutes.

However, anyone at the scene can act as an immediate responder and save lives if they know what to do. Distributed Security Inc. supports the Presidential policy directive for national preparedness (Presidential Policy Directive 8), which targets preparedness as a shared responsibility of the government, the private and nonprofit sectors, and individual citizens.

Bleeding control or B-CON was initially part of NAEMT’s curriculum. The program has now transferred to the American college of Surgeon’s group “BleedingControl.org”. DSI offers an expanded version of B-CON as part of all of its Tier 4 training courses to address the most common causes of preventable death. We can also offer B-CON as a standalone course.



  • Target audience: “Combatants” including DSI Students, security personnel, law enforcement, and military
  • Level: Tier 4
  • Duration: All Combatants (AC) Non-medical 8 hours/Medical personnel (MP) 16 hours
  • 4/5 days when combined with our Tier 3 Individual Tactics reality based training or "RBT"

The Tactical Combat Casualty Care (TCCC) course introduces evidence-based, life-saving techniques and strategies for providing the best trauma care on the battlefield. DSI offers TCCC conducts TCCC courses under the auspices of the NAEMT and its PHTLS program, the recognized world leader in prehospital trauma education.

DSI’s TCCC courses use the PHTLS Military textbook and are fully compliant with the Department of Defense’s Committee on Tactical Combat Casualty Care (CoTCCC) guidelines. It is the only TCCC course endorsed by the American College of Surgeons.

The TCCC-MP (TCCC for Medical Personnel) course is designed for combat EMS/military personnel, including medics, corpsmen, and pararescue personnel deploying in support of combat operations. DSI also offers Tactical Emergency Casualty Care (TECC) for civilian tactical EMS.

The TCCC-AC (TCCC for All Combatants) course is designed for non-medical military personnel and includes first responder skills appropriate for soldiers, sailors, airmen, and marines.

DSI’s NAEMT TCCC course is accredited by the Continuing Education Coordinating Board for Emergency Medical Services (CECBEMS) and recognized by the National Registry of EMTs (NREMT)



  • Target audience: Civilian tactical EMS; any EMS practitioner called upon to respond to a mass casualty or active shooter event.
  • Level: Tier 4
  • Duration:2 days
  • 5 days when combined with our Tier 3 Individual Tactics reality based training (RBT)

DSI offers TECC which was developed by NAEMT’s Prehospital Trauma Life Support (PHTLS) Committee. The TECC program is based on the guidelines from the Committee on Tactical Emergency Casualty Care (Co-TECC) and the Tactical Combat Casualty Care (TCCC) program. TECC uses lessons learned from our military and applies them to the civilian world of tactical medicine.
This 16-hour course covers topics designed to decrease preventable death in the tactical situation.  Topics include: Hemorrhage control; surgical airway control and needle decompression; strategies for treating wounded responders in threatening environments; caring for pediatric patients; and techniques for dragging and carrying victims to safety.

At the core of the TECC program are three distinct phases that have been well-proven by TCCC-trained personnel in the war against terrorism in Iraq and Afghanistan. The phases are as follows. 

● Direct Threat Care: Care that is rendered while under attack or in adverse conditions.
● Indirect Threat Care: Care that is rendered while the threat has been suppressed, but may resurface at any point.
● Evacuation: Care that is rendered while the casualty is being evacuated from the incident site.

TECC focuses on the medicine during these phases of care and provides guidelines for managing trauma in the civilian tactical or hazardous environment. While TECC has a tactical slant, it takes an all-hazards approach to providing care outside the normal operating conditions of most EMS agencies, such as responding to a mass casualty or active killer event.


K9 TACTICAL EMERGENCY CASUALTY CARE (K9-TECC)  This course is under development

  • Target audience: Civilian tactical EMS; K9 law enforcement officers and handlers
  • Level: Tier 4
  • Duration: 1 day
  • Prerequisite: TECC, TCCC-MP or TCCC-AC

Currently, there are currently no “official K9 TECC courses” or K9 TECC provider/instructor certifications.  We have developed a K9 TECC course that follows the guidelines developed by the Committee on Tactical Emergency Casualty Care (C-TECC) and adapted by the K9 TECC Working Group.

The resources developed by the K9 TECC working falls under the purview of the Committee of TECC (C-TECC).  The K9 TECC guidelines are open source and non-proprietary.  There C-TECC and K9 TECC working group believe that, though there are universal “principles” of high threat response, the application must be tailored for individual agencies based upon local resources, political climate, budget, and operational experience. 

K9 TECC is not dogma, and the principles are meant to be applied uniquely by each agency that uses it, depending on that agency's provider levels, the scope of practice, culture, patient population, risk assessment, etc. We consider the K9 TECC guidelines to be a pile of bricks; take only the bricks that fit into your operational culture and build a response program that is unique to you. Just don’t change the individual bricks. Similar to TECC, the principles of K9 TECC are not difficult to teach as the actual MARCH interventions such as pressure dressings, needle decompression, etc. are similar to those skills already learned for managing human casualties. The uniqueness of K9 TECC is taking the skills and knowledge medical providers already have for treating human casualties and knowing how and when to apply them to a K9 casualty. In most regards, this comes down to understanding the species differences in anatomy and physiology.

More information will be forthcoming once this course is finalized.

Training Philosophy

The Industry Standard Vs. The DSI Standard

Using military, law enforcement, and common private industry training standards as a gauge we want to give you a sense of how the DSI standard compares to the "industry" standard.

The industry standard focuses on range safety and artificiality by using tightly controlled, on-line, square range drills or movement under tightly controlled drills (such as "box" drills), in order to focus on draw speed and hits in a given area under a certain time limit. This type of training is often accompanied by hours in the classroom presenting declarative knowledge, which eats into the available live fire training time. When critical topics like use of force are taught in a classroom, rather than on your feet in the sudden, uncertain, violent and chaotic setting of combat (real or simulated) students are more likely to either overreact, or to hesitate and be afraid to apply the appropriate level of force.

DSI begins by looking at reality: the actual conditions of a gun fight. We believe that firearms skills must be integrated at the earliest possible moment with maneuver (movement with purpose). We believe that most of the declaratory knowledge can be absorbed by the student through readings, narrated videos, and dry practice drills on his schedule and on his own premises, before he ever sets foot on a range - especially if he has access to instructors to answer questions that may arise. We believe that your paid, on-range, supervised training time is a precious resource that should be maximized.

To be able to defend yourself, DSI believes you need to be killing enabled. Regardless of your technical skills, if you have not processed the issues surrounding deadly force well before the moment of crisis, if you cannot kill another when it is necessary to save yourself or other innocents, then you will fail.

Furthermore, one can only make proper decisions in lethal force engagements by way of orientation in the sense of Colonel John Boyd’s OODA Loop, and orientation only comes via experience under conditions as close as possible to those that will exist in a gunfight. Orientation relies on experiential knowledge, which cannot be attained only by reading or talking about scenarios. Nor can you survive a lethal encounter if your conscious mind is distracted from vital decisions to engage in every choice of action or technique. DSI’s training techniques develop sound, reality based semi-conditioned responses to maintain your situational awareness, maneuver safely, and react aggressively to contact. Your trained gun handling skills will take care of themselves, and the higher level conscious decisions – whether to shoot, how and whom to shoot – are fast, focused, and uncluttered. You will train this way from the start in both dry and live fire drills, and then reinforce that learning through challenging RBT (Reality Based Training) scenarios in our tactical training programs.

Solid curricula that pre-loads the declaratory knowledge, and then teaches integrated firearms and tactical skills in a reality-based environment will produce individuals and teams more capable than most military and police units. We base this statement on our personal experience of having trained thousands of military and law-enforcement personnel over 25 years). Operational police and military units (those units actively kicking in doors day in and day out) may be able to outperform our clients in certain aspects, based on that all-important factor of experiential learning (basing actions and decisions under stress on a fund of prior, applicable experience). But DSI can develop and implement effective training faster, applying the best and latest techniques and lessons-learned; and present it in a more compressed, highly effective format, because we have neither bureaucratic hoops to jump through, nor institutional inertia.
