Class Overview:

The MASS Close Quarter Battle (MCQB) Method provides one basic, principle-based method
of searching and building entry suitable for a variety of situations up to and including
“High Threat” missions.  Our system evaluates the need for both cautious and
aggressive entry as needed still using a tactically superior position using behavior-
based methodology.

The same basic principles and techniques are used at varying speeds to deal with all
types of Close Quarter Battle situations: deliberate, dynamic, stealth, and hostage
rescue. MASS Close Quarter Battle (MCQB) is suitable for solo operators, clearing you
house with your spouse, and small teams to multi-team operations with foundational
techniques that span the capabilities of the entry-level law enforcement. 

MCQB gives personnel the skill and confidence needed to address the simplest or most
serious threats while maintaining superior survivability and operational flexibility leading
to decreased liability.  The behavior-based nature of the program means that personnel
are not required to abandon their common sense or intuitive survival sense, forcing
them to use a close-range “kill or be killed” tactic that is often provably abandoned upon
contact with a determined defender, or worse, forcing a shooting situation when none is
required.  This class is taught in a two day/evening format to teach low light clearing as
well. Class runs 12 noon till 5pm with a 3-hour break then reconvenes from 8pm till 1
am both days.

The course culminates in a series of interactive scenarios using training weapons against role
players. This course is interactive, making use of shot indicating laser training pistols and
training projectiles (airsoft) against real people, and does not include live weapons or
ammunition in the training.
