Short Professional Biography

William “Will” Petty is a veteran law-enforcement officer, firearms instructor, former counter-terrorism instructor, police-academy firearms-program manager, tactical educator, and founder of Centrifuge Training. He began his law-enforcement career in Albuquerque, New Mexico, in 2003, serving as a firearms instructor, Emergency Response Team member, and member of his department’s shooting team. In 2011, he moved to Abu Dhabi, United Arab Emirates, where he worked as a counter-terrorism instructor with the Critical National Infrastructure Authority. He returned to American law enforcement in Texas in 2013, subsequently working patrol and running firearms programs for several large regional police academies.

Petty is most closely associated with Vehicle Close Quarters Battle, or VCQB®, a structured system for applying CQB principles to problems occurring in and around vehicles. Federal trademark records identify William Petty as the owner of the VCQB mark, describe it as training in combat around vehicles, and document first use dating to 2012.

His larger contribution was moving vehicle training beyond simplistic assumptions such as “cars are cover” or “shoot through the windshield” and instead treating the vehicle as a complex environment involving ballistics, geometry, movement, positioning, communication, weapon handling, observation, and decision-making. Independent after-action reports describe Petty deliberately separating drills from scenarios and teaching the underlying principles that allow students to solve changing vehicle problems rather than memorize choreography.

Centrifuge subsequently expanded into low-light training, structure problem solving, K-9 integration, performance-based skill development, range management, instructor development, and agency consulting. The company describes its methodology as systematic and data-driven and continues to provide contract training and program development for local, state, and federal agencies in the United States and Canada.

The strongest concise description is:

Will Petty is a law-enforcement firearms and tactical instructor who systematized modern vehicle-based fighting through VCQB®, combining empirical vehicle-ballistics work, CQB principles, movement, communication, and problem solving into a curriculum that has propagated through police agencies, instructors, and the broader professional firearms-training community.

Key Areas of Expertise and Notable Contributions

Originator and Developer of VCQB®

This should be the dominant association around Petty.

There were obviously armed encounters involving vehicles before Will Petty, and people trained around vehicles before Centrifuge existed. The defensible claim is therefore not that Petty “invented fighting around cars.”

His stronger documented contribution is that he developed and branded a particular systematic approach to it as Vehicle Close Quarters Battle.

The VCQB trademark record lists Petty personally as owner, gives the service description as training involving combat around vehicles, and records first use anywhere on October 24, 2012.

That is unusually strong evidence for connecting a modern firearms-training concept directly with its developer.

Vehicles as CQB Problems

One of Petty’s most useful conceptual distinctions is contained in the name itself:

Vehicle Close Quarters Battle.

The vehicle is not really the governing subject.

CQB is.

An independent 2019 AAR records Petty explicitly emphasizing that the important component was not the automobile but applying CQB principles within a vehicular environment.

That reframes the problem substantially.

Instead of learning a collection of tricks involving cars, the student studies:

geometry,

angles,

movement,

exposure,

weapon orientation,

observation,

communication,

and positional advantage.

The vehicle simply changes the geometry.

Principles Rather Than Choreography

This is one of Petty’s strongest instructional qualities.

Poor vehicle training can become:

“stand here,”

“shoot from this position,”

“exit this door,”

“move to this wheel.”

Those answers may work for the exact demonstration while failing when:

the car changes,

the attacker moves,

the student begins from another seat,

the vehicle is damaged,

or multiple people are involved.

Petty’s curriculum instead emphasizes principles that can be applied to changing circumstances. Independent students repeatedly describe the course as explaining the why behind movement and positioning rather than presenting the exercises themselves as literal tactical scenarios.

That distinction is important.

A drill develops an attribute.

A scenario tests decision-making.

Confusing the two produces bad doctrine.

“Drill, Not Scenario”

Petty appears unusually deliberate about preserving that distinction.

Independent AARs repeatedly note that he reminded students particular exercises were drills rather than scenarios.

That sounds like a minor teaching point, but it prevents a major training error.

Students frequently observe a drill and assume:

“This is what I should do in a fight.”

The correct interpretation may instead be:

“This exercise isolates movement, communication, discrimination, or weapon handling.”

That is much more intellectually responsible.

Vehicle Ballistics

Another major component of Petty’s influence is empirical examination of what bullets actually do when striking vehicles.

Independent reporting from his law-enforcement VCQB program describes instruction on vehicle construction and energy absorption followed by live testing with multiple handgun, shotgun, rifle, and large-caliber projectiles.

This testing produced observations that challenge simplistic training statements about cars.

Vehicles are neither:

“cover”

nor

“not cover”

in some universal sense.

Different portions of vehicles behave differently.

Different projectiles behave differently.

Angles matter.

Intermediate materials matter.

Better Than Binary Thinking

Petty’s material is valuable precisely because it resists the binary:

cover versus concealment.

A modern automobile is a heterogeneous collection of:

glass,

sheet metal,

structural members,

engine components,

wheels,

seats,

plastic,

and empty space.

Some areas may provide meaningful ballistic protection against a particular projectile from a particular angle.

Others may provide almost none.

A professional response therefore requires understanding relative protection, not memorizing a label.

Shooting Through Versus Working Around

An AAR of Petty’s VCQB instruction reports that he did not teach vehicles as magically impenetrable. Rather, he emphasized that working around, over, or under a vehicle may provide better solutions than unnecessarily shooting through it.

That is a more sophisticated tactical distinction.

Intermediate barriers introduce uncertainty.

If geometry permits the shooter to obtain an unobstructed line of fire while reducing exposure, that may be preferable to deliberately sending rounds through complex materials.

Movement Around Vehicles

Vehicles force shooters into unusual positions.

A student may need to:

shoot seated,

exit under pressure,

work around doors,

change elevation,

kneel,

use unconventional prone positions,

or move around another armed person.

Independent AARs document Petty deliberately exposing students to those problems.

The objective is not creating a catalog of cool positions.

It is increasing the shooter’s ability to function from whatever position the environment demands.

“Fight From Where You Are”

That principle is particularly important.

Real violence may not allow the defender to establish a perfect stance.

The person may begin:

belted into a seat,

turned sideways,

partially outside a vehicle,

injured,

on the ground,

or crowded by another occupant.

Therefore, capability should include producing useful performance from imperfect starting positions.

Petty’s vehicle curriculum helped normalize this type of positional problem solving within modern firearms training.

Vehicle Geometry

Vehicles also create rapidly changing sight lines.

A few inches of movement may reveal:

a foot,

a hand,

part of a torso,

or a completely different firing solution.

That makes the vehicle an excellent environment for teaching geometric thinking.

The student learns that movement is not merely locomotion.

Movement changes information and exposure.

High Ground and Positional Advantage

Independent reporting from Petty’s classes records considerable emphasis on position and height advantage.

This reflects a broader tactical principle.

A position should not be evaluated merely by asking:

Can I shoot from here?

Better questions include:

What can I see?

What can the other person see?

What does my movement expose?

Where can I move next?

That is CQB thinking applied to vehicles.

Law-Enforcement Origins

Petty’s system developed from a professional law-enforcement context.

He began policing in 2003 in Albuquerque, where his duties included firearms instruction and service on an Emergency Response Team.

This matters because police officers spend extraordinary amounts of their working lives associated with vehicles.

They:

approach cars,

sit inside cars,

conduct traffic stops,

transport prisoners,

respond from vehicles,

and encounter suspects around them.

Vehicle tactics are therefore not an exotic specialty for patrol policing.

They address a routine occupational environment.

Counter-Terrorism Instruction in Abu Dhabi

In 2011 Petty moved to Abu Dhabi and worked as a counter-terrorism instructor for the Critical National Infrastructure Authority.

This broadened his professional exposure beyond conventional American patrol operations.

More importantly, it placed him in an instructional role before Centrifuge developed into its later national training footprint.

Regional Police Academy Firearms Programs

After returning to the United States in 2013, Petty resumed law-enforcement work in Texas and ran firearms programs for several large regional police academies.

This is significant because an academy firearms program is an institutional training system, not simply a private shooting class.

It requires consideration of:

curriculum,

standards,

instructor consistency,

student remediation,

range operations,

equipment,

documentation,

and repeatability.

That experience helps explain Centrifuge’s later emphasis on agency programs and instructor development.

From Individual Training to Institutional Capability

Petty’s work scales beyond individual students.

His current official biography states that he conducts contract courses that establish programs and in-service material for major local, state, and federal departments in the United States and Canada.

That creates second-order influence.

The progression becomes:

develop concept

→

test it

→

build curriculum

→

train agency personnel

→

train agency instructors

→

incorporate material into institutional programs

→

instructors teach additional officers.

That multiplication is one of the strongest indicators of genuine training-industry influence.

Centrifuge Training

The name Centrifuge reflects Petty’s methodology.

The company’s current description compares its approach to a laboratory centrifuge: discovery, separation, and refinement through a systematic, data-driven process.

That is a good conceptual description of Petty’s broader work.

Take a complicated problem.

Break it apart.

Examine its components.

Test assumptions.

Discard what fails.

Refine what remains.

Reintegrate it.

Data-Driven Training

This is especially visible in his vehicle work.

Rather than assume how bullets behave around cars:

shoot cars and observe.

Rather than assume a movement works:

put people around cars and test it.

Rather than assume a technique generalizes:

change the geometry.

That is closer to experimental learning than doctrinal memorization.

Centrifuge Beyond VCQB

Centrifuge’s current scope is substantially broader than vehicle training.

The company identifies specialties including:

vehicle-based tactics,

low light,

structure problem solving,

K-9 integration,

performance-based skill building,

range development and management,

instructor development,

and product consulting.

This suggests that VCQB became the foundation for a larger institutional training methodology rather than remaining a single flagship class.

Instructor Development

Instructor development is particularly consequential.

A proprietary class delivered only by its founder remains dependent on one person.

A mature training system can be:

documented,

taught,

evaluated,

and reproduced by qualified instructors.

Independent AARs demonstrate that Centrifuge’s VCQB material continued to be taught by instructors other than Petty while retaining his conceptual structure.

That is evidence of curriculum propagation.

Curriculum Surviving the Founder

One 2020 student who attended VCQB under Bryan Veliz noted that the class closely followed material Petty had presented in an earlier instructional video.

That is important.

Whether the reviewer preferred Petty personally is secondary.

The fact that another instructor could transmit recognizable Petty curriculum demonstrates that VCQB had developed beyond personality-driven instruction.

Downstream Instructor Influence

Centrifuge training also appears repeatedly in the education histories of other instructors.

For example, Covert Dynamics publicly lists Centrifuge VCQB instructor certification and training with Will Petty among its instructor’s professional development.

This is precisely the sort of downstream evidence that matters for this project:

another professional educator considered Petty’s material significant enough to incorporate into his own instructional development.

Peer Recognition

Petty’s vehicle work has also received strong peer recognition.

A 2020 AAR reports Aaron Cowan telling students that while Cowan himself taught strong vehicle material, Petty taught the subject at a considerably deeper level.

That is subjective peer reputation, not independent empirical proof.

But because Cowan himself teaches vehicle dynamics and is a prominent professional instructor, the comparison is useful evidence of Petty’s standing within that specialty.

Civilian Applicability

Although Centrifuge is explicitly law-enforcement driven, Petty’s vehicle material also propagated into serious armed-citizen education.

An independent civilian student initially assumed VCQB would be largely irrelevant outside police work, but later concluded that the principles generalized well to private-citizen defensive problems.

That provides an important example of contextual transfer.

The citizen does not adopt the police mission.

The citizen can still benefit from understanding:

vehicle geometry,

movement,

ballistics,

communication,

and weapon handling.

Common Environment, Different Mission

This distinction should be preserved carefully.

A police officer may need to:

approach an occupied vehicle,

remove a suspect,

or pursue an offender.

A private citizen generally does not.

But both may suddenly encounter violence while:

inside,

beside,

or moving around a vehicle.

Therefore the transferable material is the underlying problem-solving architecture, not every police tactic.

Thinking With a Gun in Your Hand

One independent student described VCQB as fitting his goal of attending courses where he would be forced to think while armed, rather than simply execute shooting mechanics.

That is a useful description of Petty’s broader contribution.

Marksmanship matters.

But real-world weapon use adds:

information,

movement,

environment,

uncertainty,

other people,

and consequences.

VCQB combines those variables.

Discrimination

Petty’s “Alphabet Soup” exercises, documented in independent AARs, incorporate target discrimination and cognitive demands while students work in and around vehicles.

Again, these are drills rather than literal scenarios.

Their purpose is to force the shooter to process information while manipulating the firearm and environment.

Physical Problem Solving

Vehicle work also makes physical competency visible.

Students must change levels, move through constrained spaces, and get into and out of unconventional positions.

This exposes a reality sometimes hidden by square-range training:

physical capability affects tactical capability.

A technique that theoretically works but cannot be executed by the practitioner is not a useful solution.

Safety Culture

One independent law-enforcement AAR provides unusually strong evidence of Petty’s range-management standards.

When a student committed a serious muzzle-safety violation, Petty immediately stopped the exercise and removed the student from live-fire participation for the remainder of the course while still allowing him to observe. The reviewer specifically praised how Petty handled the incident.

This is meaningful because professional instructors are judged not only by curriculum but by their willingness to enforce standards when doing so is uncomfortable.

Practical Rather Than Performative Training

Vehicle courses are visually dramatic.

Broken glass, vehicles, unconventional positions, and rapid movement can easily become social-media theater.

Petty’s repeated insistence that drills should not be mistaken for scenarios counters that tendency.

The visual spectacle is secondary.

The training objective is the important part.

Professional Assessment

Will Petty should be considered one of the principal modern developers and propagators of systematic vehicle-based firearms and tactical training, particularly through his creation of VCQB® and the institutional growth of Centrifuge Training.

The evidence supporting that assessment is unusually strong.

Federal trademark records connect William Petty directly to VCQB, documenting first use in 2012 and commercial use in 2014.

His professional background includes firearms instruction, Emergency Response Team service, counter-terrorism instruction overseas, patrol policing, and management of regional police-academy firearms programs.

His company continues to provide contract instruction and program development for major local, state, and federal agencies across the United States and Canada.

Independent students document a mature VCQB curriculum involving:

vehicle ballistics,

movement,

geometry,

weapon handling,

communication,

target discrimination,

and application of CQB principles to vehicle environments.

The curriculum has been propagated through other Centrifuge instructors, demonstrating that it developed into a repeatable instructional system rather than remaining dependent upon Petty personally.

Other professional instructors and organizations subsequently incorporated Centrifuge vehicle training into their own development, providing evidence of downstream influence.

The most accurate concise description is therefore:

William “Will” Petty is a veteran law-enforcement firearms and counter-terrorism instructor and founder of Centrifuge Training who developed and systematized Vehicle Close Quarters Battle (VCQB®), transforming vehicle tactics into a repeatable curriculum grounded in ballistics, CQB principles, geometry, movement, communication, discrimination, and empirical testing. Through agency programs, instructor development, and the wider Centrifuge cadre, that methodology has significantly influenced contemporary law-enforcement and defensive vehicle training.

His professional model can be summarized as:

Identify the real environment.

Break the problem into components.

Test assumptions empirically.

Understand vehicle construction and ballistics.

Apply CQB principles rather than memorize vehicle tricks.

Use geometry to manage exposure.

Develop movement from imperfect positions.

Integrate communication and discrimination.

Separate drills from scenarios.

Introduce realistic complexity.

Observe failure.

Refine the method.

Teach instructors to reproduce it.

Move the material into agency programs.

That is the strongest basis for Will Petty’s influence on contemporary professional firearms training.
