The centrifuge is a simple yet effective machine. It can be found in laboratories rotating at high speed utilized as a process of discovery, isolating and refining its contents. It is this same systematic, data-driven approach Centrifuge, LLC utilizes in delivering pragmatic solutions to the modern problem solver.

Vehicle CQB is an accelerated shooting class focused on positional shooting and a critical look at how we have historically fought in and around vehicles.  Students will push the boundaries of “traditional” cover and concealment utilizing various cars and trucks in a true 3D environment. Drills will incorporate critical weapon employment while engaging threats in, around, from, over and under vehicles with a heavy emphasis on problem solving. Live ballistic demos with a variety of ammunition will be conducted as the class explores ballistic deflection, deformation, penetration and terminal effect in direct correlation to various vehicle mediums. Both days of this course will be long days, so come prepared.

There are bad days at the office… and then there are really, really bad days at the office. “Well, That Sucks” explores the latter. Students will learn to employ the handgun and carbine while problem solving different simulated injuries. Improvised aide, TQ application and evacuation are worked through then performed on demand under stress. Communication, teamwork, movement, accelerated manipulations and task vs. priority all play a major role in this course. This is NOT a basic or beginners’ course and is physically demanding; please come prepared.
