Modules of instruction will include:

Friday Evening (1800-2100):

INTERACTING WITH UNKNOWNS (Managing Unknown Contacts): Enhancing Safety in Daily Life
The vast majority of people encountered in our daily lives are of no interest or concern to us at all. A tiny percentage are actively malevolent and mean us harm no matter what we do and must be actively managed with applied defensive skills. However, a much larger fraction exist in an ill-defined space between: a space where interest, concern, risk, and threat exist in and emerge from a fluid universe of signs and signals. In a series of controlled exercises, attendees will learn a simple, practical, and robust method for determining the appropriate course of action with unknown subjects. No prior experience or training in defensive tactics is required, no special physical gifts are necessary and the material is presented in a from-the-ground-up approach to allow conceptual understanding and physical grasp of an intuitive skill-set in a relatively short time.

Saturday (0800-1700):
UNTHINKABLE is, in brief, a tour of the dark side of our society: criminal violence. In one very full day, attendees will undertake a fast-paced and interactive overview of how Violent Criminal Actors think as they decide whom to victimize, focusing on our demeanor and behavior for cues that we appear easily victimized. Hands-on training will introduce robust, effective techniques for managing interactions with unknown contacts, who may or may not intend us harm, including disarming an assailant armed if necessary. The day will finish with an in-depth review of the psychological and social development of VCAs, with particular attention paid to incorporating this knowledge into a powerful, adaptive mindset of self-protection.

Attendee Feedback
“I wish everyone important to me would take this class.”
-UNTHINKABLE attendee, 2015

William Aprill is one of the most important thinkers in the defensive shooting world today. His insight into what makes criminal attackers “tick”, as well as his understanding of the psychological aspects of training and response, are valuable to everyone who has a firearm for personal defense.
-Grant Cunningham, educator and trainer (

“If I could go back in time I would trade every moment I’ve ever spent in a carbine course to listen to William Aprill’s lectures in the Unthinkable class because THAT information was the kind of stuff I needed.
-UNTHINKABLE attendee, 2014

The gun is certainly a wonderful and very powerful tool, but it’s not wise to pin your survival strategies only upon the possession of that tool. “Unthinkable” arms you with information. Critical, crucial knowledge that may not be needed every day, but if the unthinkable happens it gives you enough exposure to know there is almost always something you can do to improve your situation. The exposure opens your mind…

Course Description:
• How do violent criminals think of us, and how do they target us?
• How are human monsters made, and born?
• What do we do when faced with unknown threats, even against a drawn gun?

All these questions recall threats that any reasonable person would avoid at any cost. So why would anyone pay to spend a day immersed in exploration of those threats and more? Simply put, there is no way to develop an effective and adaptive defensive mindset without spending time in some fairly dark places.

This course will explore the above domains and skill sets, guiding students to the next step in developing their ability to protect themselves and those they love.

For participants in this course, a systematic approach to enhancing personal safety will be undertaken in an engaging and fast-paced format over a very full day of training.

Since defensive awareness is rooted in realization of risk, and since defensive preparation adds the commitment to mitigation of threats, unifying those elements in defensive decision-making will be the emphasis of this course.

It is the goal of the instructor to drag awareness of risk from the back of the mind to its very forefront, ensuring that an actual life-threatening scenario will not be the first time participants have honestly faced what will be necessary.

Participants in this course will be presented with some challenging truths about the world as it is and asked to make serious, personal changes in how they prepare for that world.

Classroom components will include intensive, interactive lecture including:
Fatal Choices: Understanding VCAs and Victim Selection
In this fast-moving and interactive lecture participants will be led through contemporary theories and current, curated data on the process by which violent criminal actors select their targets for violent aggression. Particular attention will be paid to the internal mechanisms in play within the criminal psychology, the universe of signifiers around “good guy” behavior, demeanor, and attributes which may actually make selection for attack more likely, as well as considerations for responsible armed citizens to mitigate this risk. Previous iterations of this material have been presented to law-enforcement agencies and private citizen groups across the US as well as international LE educational events.

Violent Acts & Actors: A Conceptual and Practical Overview
Many instructors present material on surviving physical attack, some address the aftermath of that defensive violence, however the preparation for being placed at risk or even physically attacked is given limited attention at best. This “pre-kinetic phase” is, in contrast, the entire focus of this course. In this wide-ranging and fast-moving program, attendees will be introduced to current understanding of the scope and scale of criminal violence, typologies of such violence, and an in-depth tracing of the developmental path of those who inflict such violence on others. Significant attention will be paid to translation from academic concepts and theories to actionable material with relevance at the street level. Attendees may hope to leave with a far greater understanding of the origins of and motivation for the seemingly senseless violence that wreaks havoc on so many communities, as well as greater insight into steps necessary to maximize their capacity for self-protection.

Sunday (0800-1700):
Learn to overcome a violent assault and advance to safety by building your ability to control a situation: Featured in several national and international magazines, Paul Sharp’s MULTI-DISCIPLINARY OPTIMIZATION COURSE (MDOC) is a comprehensive training program that takes a systematic approach to integrating and instructing Mixed Martial Arts and combative sports for those working in a weapon-based, Extreme Close Quarters environment. This course will introduce students to a foundational set of self-preservation principles and easily-replicated drills for future training.

Expanded Principles of Initiation and Escape

Attached Striking

Expanded In-Fight Weapons Access (IFWA)

Required Equipment: Comfortable clothes, wrap-around eye protection, mouthpiece, cup.

Recommended Equipment: Training drones of preferred EDC tools as well as support gear such as holsters or magazine pouches. A red or blue dummy gun is acceptable. NO LIVE WEAPONS ARE PERMITTED IN THE TRAINING ENVIRONMENT.
