Second Generation Collapsible Defense System

The SOB II is an evolution of the legendary collapsible defense system pioneered by Special Ops Bunker. It is designed for efficient transport and quick deployment. After all, armor is worthless if you can’t take it with you.

Our unique patented design allows the SOB II to collapse into a single compact unit, small enough to fit in the trunk of a patrol car for transport or storage. It’s even more compact than the original SOB! When you need the SOB II it can be fully deployed in one minute or less. This makes the SOB II ideal for a broad range of tactical deployments.

The SOB II comes standard with modular side shields that can be quickly removed to function as hand-carry shields. The side shields are hinged so they can swing back, offering added protection on the sides; this also allows the SOB II to pass easily through a single doorway. When placed in the forward position the side shields offer a wider overall ballistic protection area.

The SOB Armor System is rigorously tested and certified to exceed NIJ Level IV requirements. Wheels, axles, and run-flat tires can also withstand multiple gunshots.
