The Sentinel Ballistic Whiteboard™ is the ideal ballistic protection product for the classroom, conference room, or lobby.  Designed to prevent active shooters from seeing through, shooting through, and forcing their way through doors and other points of vulnerability, Sentinels can also be used to block a hallway while students or employees evacuate, and provide ready-to-use rolling ballistic shields for school resource officers and other first responders.  When not called on for such emergency service, the Sentinel makes a great teaching aid or announcement board for everyday use.

For those of you who are not ballistics geeks like we are, permit us to share some basic information about active shooter threats.  The two main families of assault rifles used worldwide are the AR-15 which typically shoots the 5.56x45 mm cartridge and the AK-47 which typically shoots the 7.62x39 mm cartridge.  5.56x45 mm bullets are light and fast and can be a significant threat to steel armor due to their high strike velocity.  7.62x39 mm bullets are slower and can be more easily stopped.  The 7.62x51 mm round, specified by the National Institutes of Justice as the threat round for Level III (non-armor piercing) rifle protection, is primarily used in deer rifles, tactical “sniper” rifles, and belt-fed machine guns – all of which are fortunately very rarely used in active shootings.  The AR-15 is far more common than the AK-47 in the United States such that the 5.56x45 mm is the centerfire rifle cartridge most often used during active shootings.

All Sentinels are manufactured from premium mil-spec ballistic steel.  We do not use the cheaper AR500-type steel designed for dump truck beds and bulldozer blades.  Because of this the Sentinel can withstand the 5.56x45 mm full metal jacket round at an impressive 3100 fps.  This is by far the most common type of 5.56x45 mm cartridge and it can be a significant threat to steel armor due to the bullet's high strike velocity which can punch through a steel panel before the material has time to yield and absorb the bullet energy.  NIJ Level III steel panels typically perform poorly against this round.  Hence most manufacturers perform additional testing and rate their products as “NIJ III+”.  However this additional testing is entirely up to the manufacturer, and knowing which threat rounds are tested and at what velocities is critical to understanding the product’s capabilities.  If a product does not explicitly state that it can stop the 5.56x45 mm full metal jacket (M193) round with at least a 3000 fps velocity in their ballistic certification it may not reliably stop AR-15 bullets in a real world shooting.  Also ensure the testing was done at an outside laboratory per NIJ test protocols, not by the manufacturer.  Some companies have been known to use short barrels and known cheap/low energy ammunition to help their products "pass" testing.  The 5.56x45 mm M855 green tip cartridge features a slower bullet and was designed to penetrate sheetrock, car bodies, plywood, etc. but breaks up upon striking hardened ballistic steel.  Ballistic certification against this round is NOT an adequate substitute for the M193 projectile if you want to stop AR-15s, although many manufacturers seek to cover inadequacies vs the M193 by testing against the M855.  Ask to see their ballistic test certifications.  Note that a significant portion of active shootings are carried out using handguns or shotguns which will be easily stopped by any rifle-rated product.
